1.3 Introduction
The piccolo xpress™ chemistry system is compact and easy to transport. The system consists of a
portable analyzer and single-use disposable reagent discs. The analyzer contains the following
features and components:
■ a variable-speed motor to spin the disc
■ a photometer to measure analyte concentrations
■ two microprocessors to control testing and analytical functions
■ a thermal line printer to print out results
■ a VGA color touchscreen for communicating with the analyzer
■ optional data functions for more detailed analysis information
Each reagent disc is self-contained clear plastic, 8 cm in diameter and 2 cm thick, and containing
an aqueous diluent in its center and dry reagent beads in cuvettes around its edge. All blood sepa-
ration and sample diluent mixing is performed within the disc itself.
To perform an analysis, the operator needs only to collect a blood sample (lithium-heparinized
whole blood or plasma, serum), place the sample in the reagent disc, put the disc into the analyzer
drawer on the front of the analyzer, and input patient information. When analysis is finished, the
results print automatically.
Results are printed on thermal paper with adhesive backing for inclusion within the patient's med-
ical record. Five USB ports are provided so data can be sent to an external printer, computer,
memory stick, or laboratory information systems/electronic medical record systems (LIS/EMR).
The entire analysis requires ~100 μ L of sample and is capable of providing results in about
12 minutes.
Note: This manual includes a number of analyzer screens and computer
screen captures. The analyzer screens are illustrations only, not exact
duplications. All screens represent typical use and installations, and
may differ in some minor details from the screens on your system.

2.4 piccolo xpress™ System Description
The piccolo chemistry system consists of a portable analyzer and
disposable single-use reagent discs. Each reagent disc contains all
the reagents needed to perform a panel of tests on a single sample.
Be sure to become familiar with the system before running samples .
The piccolo xpress™ analyzer uses centrifugal and capillary forces to process heparinized whole
blood samples and distribute diluted plasma to the reaction chambers (cuvettes) in the reagent
disc. Serum and heparinized plasma samples are processed in a similar manner. The analyzer opti-
cally measures the chemical reactions and calculates analyte concentrations from these measure-
ments and from encoded calibration data contained on the bar code ring on the reagent disc.
Results are stored in memory, and can be printed using the built-in thermal printer or downloaded
to an external personal computer for data management.
2-4 Setup and Description
Page 13
The touchscreen display provides easy communication with the analyzer. The touchscreen shows
procedural instructions, indicates the status of the analyzer, and presents any error messages. For
details, see Section 2.5.
The reagent disc drawer slides out from the front of the analyzer, and transports the reagent disc
(see Section 2.6 ) into the analyzer and automatically positions it for analysis.
The analyzer prints results on adhesive-backed thermal paper tape, through its internal printer.
The external power adapter changes the electrical outlet voltage to DC voltage required by the
analyzer. Two power supply cords are provided: one cord is connected to the power adapter and
plugs into the back of the analyze, while the other connects the power adapter to a surge protector
designed for use with a computer.
The analyzer has several USB connectors. Use the top USB connector for connecting to an exter-
nal computer (see Section 10, “Connecting a Computer/Printer” for details).
The analyzer is easy to carry using the recessed handle incorporated into the top of the unit.

2.6 Reagent Discs
Disc structure and function
In the piccolo® system, all chemistry reactions are performed inside clear plastic reagent discs,
8 cm in diameter and 2 cm thick, specially designed to perform all the steps required to convert a
few drops of whole blood, plasma, or serum into a panel of test results. Each disc contains all the
components and reagents needed to perform one or more tests on a single sample.
A total of 30 cuvettes are located around the periphery:
■ four system cuvettes contain QC reagent beads for
instrument and chemistry quality control
■ a minimum and a maximum absorbance cuvette are
used to calibrate the spectrophotometer
■ a specially designed cuvette detects whether sample
volume was sufficient
■ a cuvette verifies that sufficient diluted sample was delivered to the reaction cuvettes
■ an empty cuvette captures excess fluids
■ 21 cuvettes contain test-specific lyophilized reagent beads.

The bar code ring attached to the top of the reagent disc contains calibration data for the specific
chemistries in the disc. It also contains the disc identification code, lot number, and expiration
date. The analyzer automatically checks the code and rejects any expired disc. The bar code ring
also protects the optical surfaces of the cuvette from fingerprints and debris, and helps minimize
contamination of the analyzer by capturing small drops of blood that may be on the disc surface.
The sample port , marked by an arrow pointing to a molded circle on the disc’s upper surface,
provides access to the sample chamber. When sufficient sample has been loaded into the sample
chamber, the sample fill line forms between two molded arrows on the disc surface.
A sample diluent is sealed in a container inside the center of the disc. At the beginning of the
reaction cycle, the analyzer opens this container and releases the diluent.
The analyzer separates a lithium-heparinized whole blood sample by centrifugation inside the
disc. Plasma and serum samples are unaffected. Precisely measured quantities of sample and dilu-
ent are delivered to the mixing chamber. Centrifugal and capillary forces then deliver the diluted
sample to the cuvettes, where it dissolves the reagent beads and initiates the chemical reactions.
Reaction products in the cuvettes are then measured photometrically.

Disc Storage and Handling
CAUTION: Discs are fragile — always handle with care. Do not tap discs on the table or
work bench to empty the sample port. Do not use a disk that has been dropped.
Inspect every reagent disc for damage before use. Never use a damaged disc.
■ Store each reagent disc as described on its label. This keeps the disc’s reagents stable
until the expiration date printed on the disc’s foil pouch and encoded in its bar code
ring. The analyzer automatically rejects any expired disc.
■ Discs can be used directly from the refrigerator (stored at 2–8 °C) without warming.
■ A disc can remain in its sealed pouch at room temperature for a cumulative period of
48 hours. Longer time at room temperature can cause suppression of chemistries and
disc cancellations.
■ Do not expose discs — in or out of their foil pouches — to direct sunlight or to tem-
peratures above 32 °C (90 °F).
■ Inspect the unopened foil pouch for tears and punctures. A torn or damaged pouch
can allow moisture to reach the disc and reduce reagent performance.
■ Open the disc pouch at the notch on the top right edge of the package.
Note: You must use the disc within 20 minutes of opening its pouch.
■ Once the pouch is opened, do not place the disc back in the refrigerator for later use.
■ Keep discs clean. Handle them only by their edges to avoid smudges on the optical
surfaces. Use a lint-free tissue to remove any spilled blood from disc surfaces.
■ Optional: Write the patient identification
number on the disc surface in the space shown
Write patient
ID here
at right. Do not write anywhere else on the
disc, or on the bar code ring.
■ Hold reagent discs flat after introducing the
sample or control to avoid spillage.
WARNING: BIOHAZARD: Used reagent discs contain body fluids. Follow good labora-
tory working practices. Handle all used discs as if they are contaminated
with hepatitis or other infectious diseases. Check with the appropriate state
agency regarding disposal regulations. For more information, see
Section 1.2, “Universal Precautions,” on page 1-1.

3.1 Sample Requirements
■ The piccolo xpress™ chemistry analyzer accepts lithium-
heparinized whole blood, plasma, or serum samples.
■ Lithium heparin is the only anticoagulant recommended
for use with the piccolo xpress™.
Note: When collecting the sample in lithium heparin
collection tubes, fill the tube at least half-way
so the anticoagulant does not become too
concentrated in the sample.
■ If using CLIA '88 Waived reagent discs: only lithium-
heparinized whole blood can be used as a sample.
■ If performing a Basic Metabolic Panel Plus: only lith-
ium-heparinized plasma or serum can be used as a sam-
ple. Heparinized whole blood cannot be used.
■ A sample size of 90–120 µL is required.
■ Whole blood must be analyzed within 60 minutes of col-
lection, or separated into plasma or serum.
■ To prevent hemolysis, do not refrigerate or shake whole
blood.
■ If not analyzed immediately, plasma or serum can be
stored at room temperature for no longer than 5 hours
after centrifugation. If storage for more than 5 hours is
required, refrigerate the sample in the stoppered tube at
2–8 °C (36–46 °F) for no longer than 48 hours, or store it
at –10 °C for up to 5 weeks in a freezer with no self-
defrost cycle. Under these conditions, there will be no
clinically important changes in most analyte concentra-
tions.
■ For accurate interpretation of glucose results, the patient
should fast for at least 12 hours before the sample is col-
lected.

Step 1 — Dispense the Sample
Use a micropipette (one is included with the piccolo xpress™) or other transfer device to dispense
approximately 100 µL of sample into the disc via the sample chamber.
Write patient
ID here
CAUTION: Wear powder-free gloves while handling reagent discs or operating the ana-
lyzer. Powder can disrupt the analyzer’s optical components.
a. Fill the sample chamber.
1. Using the Piccolo 100 µl volume pipette, firmly attach a new tip to the end
of the pipette. DO NOT touch the tip (this could cause a false elevation of
amylase).
2. With your index finger or thumb, push the pipette button to the stop posi-
tion and hold it down for sample pickup.
3. Immerse the tip 2–3 mm below the surface of the sam-
ple, as shown at right.
4. SLOWLY release the button to pick up the sample.
Pause, then remove the pipette from the sample tube.
5. Make sure there are no air bubbles or air gaps in the pipette tip.
6. Place the pipette tip into the disc’s sample chamber,
and tilt the disc to 45° with the sample port above the
fill line, so that the entire sample flows into the sam-
ple chamber. The tip should touch the sample cham-
ber, as shown at right.
Testing and Results 3-3
Page 22
7. Push the plunger down with a slow, continu-
ous motion. Take care not to overfill the
sample chamber. A 90 µL sample will fill
90 μ L
the sample chamber and form a line
between the two arrows molded on the disc.
More than 120 µL of sample will overfill
the chamber.
8. Discard the pipette tip into a biohazard con-
tainer.
9. Clean the reagent disc. Use a lint-free tissue to remove any sample spilled
on the outside of the disc, taking care that the tissue does not withdraw any
sample from the sample port. Dispose of the tissue in a biohazard con-
tainer.
b. Optional: Label the disc.
Write the patient ID on the disc surface in the space shown on page 3-3 . Do not
write anywhere else on the disc or on the bar code ring.
c. Carry the prepared disc to the analyzer.

3.5 Results
The results calculated by the analyzer are stored in memory and printed automatically, and can
also be recalled and printed later as needed. If the analyzer is connected to an external computer,
the results are automatically transmitted as soon as they are calculated (see Section 10 ). See
Section 8.2, “Principles of Operation” for the basic procedure and equations used to calculate ana-
lyte concentrations.
The figure at the right shows the contents of a typical results print-
out. The heading of the results printout includes information such
as the reagent disc type, test date and time, sample type, sample ID
number, alternate ID number, gender, age, operator ID number, disc
lot number, and analyzer serial number. The test results section of
the card is printed in four columns: chemistry name, analyte con-
centration, reference range, and specified units, as shown at right.
The results printout has an adhesive backing so it can easily be
placed into the patient's file.
Each reagent disc contains reagents to detect exposure to extreme
conditions such as temperature and humidity. The message “QC
OK” is printed on the results when results from these reagents are
within the expected ranges. Otherwise, no results are printed, and
the analyzer opens the disc drawer.
■ Results outside the reference range are indicated in
the results by an asterisk (*) printed next to the ana-
lyte concentration.
■ Results outside the dynamic range are indicated in the results by a “less than” sym-
bol (<) printed next to the lowest value of the dynamic range, or a “greater than”
symbol (>) printed next to the highest value of the dynamic range.
For example, the dynamic range of glucose is 10–700 mg/dL. A sample concentra-
tion of glucose below this range would be printed as <10 mg/dL, and a concentra-
tion above this range would be printed as >700 mg/dL. Results outside the
dynamic range should be reported as being below or above the value indicated.
■ The symbols “~~~” are printed in place of numbers when a result cannot be deter-
mined — that is, when the result is suppressed. A result may be suppressed due to
improper mixing of a reagent bead with diluted sample, a nonlinear reaction, an
endpoint of a particular reaction not reached, or a concentration outside the ana-
lyzer’s capabilities. When a chemistry is suppressed (~~~ ), the analyzer prompts
the operator to print an error report.
Testing and Results 3-11
Page 30
■ For the lactate dehydrogenase (LD) assay only:
Blood cells contain significant levels of LD, and therefore all LD assays are sensi-
tive to hemolysis caused by release of LD from red blood cells. In the following
circumstances, the results are annotated to help interpret LD activity in the pres-
ence of small amounts of hemolysis.
❑ If HEM is greater than 50 and less than or equal to 100 mg/dL, the
printed LD value is followed by an “H” indicating additional influence
from hemolysis.
❑ If HEM is greater than 100 and less than or equal to 150 mg/dL, the LD
value is preceded by “<” and followed by “H”, indicating that the true LD
recovery is less than reported.
❑ If HEM is greater than 150, no result will be indicated and only “HEM”
will be printed.
■ HEM, LIP, or ICT is printed in place of the analyte concentration if hemolysis,
lipemia, or icterus, respectively, has adversely affected the results. LIP is also
printed if both lipemia and icterus have been affected. HEM is also printed if
hemolysis and icterus, hemolysis and lipemia, or hemolysis, lipemia, and icterus
have affected a particular analyte. Examine the sample indices to determine if
more than one interferent is affecting a particular result.
■ The sample indices are included at the bottom of the results printout. These indices
indicate the degree of hemolysis, icterus, and lipemia found in the sample. Hemol-
ysis, icterus, and lipemia are measured on a scale of 0 (clear), 1+ (slight), 2+ (mod-
erate), and 3+ (gross).
If the sample is identified as hemolytic, collect a new sample and run another reagent disc. Abaxis
recommends that the new sample be separated into serum or plasma so that the degree of hemoly-
sis can be verified. If the new sample is hemolytic, use an alternative testing method or send the
sample to a reference laboratory. Samples with hematocrit in excess of 60% packed red cell vol-
ume may appear on the result card as HEM. Follow the instructions above for retesting hemolyzed
samples.
High lipemia may be due to diet. Ensure the patient has fasted for at least 12 hours before collect-
ing another sample. For suggestions on testing grossly lipemic or icteric samples, see “Trouble-
shooting” on page 7-1. For grossly lipemic samples from fasting patients or for icteric samples,
use an alternative testing method or send the sample to a reference laboratory.

4.15 Running Controls
A control is a biological sample or solution with a suitably contrived matrix that is analyzed for
purposes of quality control. The composition of the matrix must be such that the solution closely
matches that of the biological specimen for characteristics of importance to the analyzer. Control
materials need to be stable and available in sufficient volumes in multiple portions and over an
extended period. Many control products are available commercially. Assayed controls also come
with expected values of the analytes for guidance.
Abaxis recommends control testing as follows:
■ at least every 30 days
■ whenever laboratory conditions have changed significantly
■ when training or retraining of personnel is indicated
■ when test results do not match patient symptoms or clinical findings
Good laboratory practices include the recording of the QC data according to the laboratory’s
established written procedures. A permanent record of control results should be retained.
4-34 Configuring the Analyzer
Page 67
Samples and controls are run identically by the analyzer. However, using the Run Controls option
in the Menu function stores control results separately from patient results in the analyzer memory.
Control results can be printed on a result card immediately after the conclusion of the control run,
or whenever the control run results are recalled. (See Section 5 for information on using the
RECALL key.) Control results are automatically transmitted to a linked computer.
Handle the control as described in the control package insert. Call Abaxis Technical support for
assistance in interpreting control results.
The analyzer automatically stores control results in a memory separate from the patient results
memory. The Recall function can be used to search for specific control results without searching
through all patient results stored in memory.
Note: Before a control can be run, a control level must be enabled in the
reference ranges — see page 4-9 .
Controls can be run whenever the analyzer displays the Home screen.
Note: For more details on running controls, see “Preparing the Reagent Disc”
on page 3-2.
CAUTION: Discs are fragile — always handle with care. Do not tap discs on the table or
work bench to empty the sample port. Do not use a disk that has been dropped.
Inspect every reagent disc for damage before use. Never use a damaged disc.

Section 5
Recalling Results
The piccolo xpress™ chemistry analyzer includes a Recall function that
provides access to the results of the most recent tests, including patient
results, control results, and test errors.
The Recall function is available from the analyzer’s Home screen.
The operator can search results by sample ID number or date, or view
patient results or control results by date. The operator can also view the
results in memory one record at a time. The results can then be printed,
or transmitted to a computer.
Troubleshooting Flags
The piccolo xpress™ performs a series of internal quality checks to
ensure accurate results. When the analyzer detects a problem, it either
suppresses certain chemistry results (in which case it prints trouble-
shooting “flags” — ~~~ , HEM, LIP, or ICT — in place of values), or
cancels the run (the disc cancels and no results are printed). When either
of these situations occur, print or transmit an error report as described in
Section 5.2.
The remainder of this section includes instructions for recalling, view-
ing, and printing or transmitting results and reports:
■ Section 5.1, “Recalling the Results of the Last Disc Run,”
on page 5-2
■ Section 5.2, “Searching for Results,” on page 5-3
■ Section 5.3, “Browsing Results,” on page 5-8
■ Section 5.4, “Transmitting All Results,” on page 5-10
Note: The analyzer must be connected to a com-
puter to transmit results — see Section 10 for
instructions.

Calibration & Q. C.
6.1 Calibration
The piccolo xpress™ chemistry analyzer is self-calibrating. The bar
code on the reagent disc contains the required information to perform its
calibration when ever a reagent disc is run. Additionally, each reagent
bead used in the disc is calibrated to a reference method and/or reference
material. If the recommended procedures in the previous sections of this
manual are followed, the analyte concentrations produced by the ana-
lyzer will be accurate.
6.2 Quality Control Features
The piccolo xpress™ includes quality control features such as optical
sensing and electronic feedback systems, to ensure that accurate results
are reported. The analyzer performs tests on both internal components
and the reagent discs whenever the power is turned on and/or a reagent
disc is inserted. Additionally, the analyzer continues to perform tests
during analysis. Messages on the display or on the result printout warn
of analyzer malfunctions and possible errors or explain why no results
are reported.
1. Intelligent Quality Control (iQC)
The piccolo xpress™ hardware performs an iQC test whenever
power is turned on. iQC ensures that all optics, flash, and circuit
board components are functioning properly and verifies the
memory functions. The analyzer performs this analysis only
when the iQC confirms that all components are functional.
A hardware malfunction message appears on the display if any
component malfunctions.
Calibration & Q. C. 6-1
Page 82
Statistical methods are incorporated into the analyzer software to ensure the accuracy of
the results. The lamp flashes up to 13 time points for rate chemistries and typically three
time points for endpoint chemistries. The distribution of flashes at each time point is ana-
lyzed and the standard deviation is compared to a pre-determined limit to ensure the ana-
lyzer is functioning properly.
2. Quality Control During Analysis
During an analysis, the analyzer’s internal components and the reagent disc are checked to
ensure the accuracy of the results.
a. piccolo xpress™ Analyzer
The analyzer’s photometer takes readings with the light path obstructed and unob-
structed to determine the appropriate light intensity range, and then checks that the
range is within specification, before analysis begins. It also continually checks the
performance of the motor, flash, and optics during analysis as well.
b. Reagent Disc
The analyzer performs several tests on the reagent disc during the analysis. These
checks confirm:
■ calibration factors
■ expiration date
■ all reagent beads are present
■ timing of fluid movement through the disc
■ diluent and sample mixing
■ sufficient sample has been applied to the disc
■ reagent beads dissolve when mixed with diluted sample
Each reagent disc contains reagents to detect exposure to extreme conditions such as
temperature and humidity. The message “QC OK” is printed on the result printout
when results from these reagents are within the expected ranges. Otherwise, no
results are printed, and a “run canceled” message is shown on the display.
The analyzer monitors the performance of the reactions. For rate chemistries, the
analyzer confirms that the reactions are linear with time, that the slope is within
range, and whether the substrate has been depleted. In endpoint chemistries, the ana-
lyzer verifies the flatness (completeness) of the endpoints.
6-2 Calibration & Q. C.
Page 83
c. Sample
Samples are checked for physical interference. The analyzer estimates the sample
indices, hemolysis, lipemia, and icterus using absorbance readings for the sample at
340 nm, 405 nm, and 467 nm. This information is then compared to pre-established
limits for hemolysis, lipemia, and icterus for each method. When all three indices are
below these limits for the method, the result for that method is printed on the result
card. When even one index exceeds the limit, the result for the method is suppressed
and the error condition displayed as HEM, LIP, or ICT.
6.3 Running External Controls
The Run Controls menu function (see Section 4.15 ) automatically stores control results in a mem-
ory separate from the patient results memory. The Recall function may be used to search for spe-
cific control results without searching through all patient results stored in memory.

Troubleshooting
7.1 Error Messages
The analyzer can display warning and error messages when problems
occur. These messages include an internal error code that will assist
Abaxis Technical Support in diagnosing the problem. Record the error
message and/or print an error report before calling Abaxis Technical
Support at 800-822-2947.
7.2 Electrostatic Discharge
If the analyzer experiences an electrostatic discharge while running a
sample, it may “freeze up.” If this happens, cancel the analysis (see
page 3-10), then power the analyzer off and back on again. This should
restore the analyzer to operating condition.

Operating Principles
8.1 Principles of Procedure
The operator introduces a heparinized whole blood sample (or heparin-
ized plasma, serum, or control) into the reagent disc. The reagent disc
contains a diluent and test-specific reagent beads. The operator then
places the disc in the piccolo xpress™ chemistry analyzer and enters the
appropriate identification numbers. The analyzer automatically performs
the remainder of the testing protocol.
The reagent disc spins and whole blood is separated into plasma and
blood cells. During this time, the disc is heated to 37 ºC (98.6 ºF). Pre-
cisely measured quantities of plasma and diluent enter the mixing cham-
ber and are mixed together. Through centrifugal and capillary forces, the
diluted plasma is distributed to cuvettes on the perimeter of the disc.
Reagent beads in the cuvettes are dissolved by the diluted plasma. This
solution is thoroughly mixed and the resulting chemical reactions are
monitored photometrically by the analyzer. Optical signals generated by
the chemical reactions are used to calculate analyte concentrations. Cali-
bration data specific for the chemistries in each disc are provided to the
analyzer by the bar code printed on the bar code ring.
After the analysis is completed, the results print automatically. Analyte
concentrations and reference ranges for each test in the panel and sample
indices are included on a printout, providing a paper copy of the results.
Results are also stored in the analyzer’s memory and can be transmitted
to external computers. The used reagent disc is removed and discarded.
The piccolo xpress™ is then ready to analyze another sample.
Operating Principles 8-1
Page 90
8.2 Principles of Operation
Chemical reactions occur between reagent beads, the diluent contained in the reagent disc, and the
added sample. These reactions produce chromophores that are measured photometrically by the
piccolo xpress™. The microprocessor then calculates the concentrations of the analytes.
The measurement optics include a stroboscopic xenon lamp, a wavelength selection system, and a
multiple-wavelength detector. Light from the lamp is directed by a mirror to pass through each
cuvette. Some light is absorbed by the cuvette contents and the remainder travels through two
apertures and is then collimated by a lens. Collimated light is split by beam splitters and interfer-
ence filters at pre-determined wavelengths (340, 405, 467, 500, 515, 550, 600, 630, and 850 nm),
and captured at each wavelength by photodiodes.
The chemical reactions utilized in the tests are designed to produce chromophores that absorb
light at known wavelengths. The photometer measures light that is transmitted through a chro-
mophore-containing cuvette (the reaction cuvette). The transmitted light, when corrected for
flash-to-flash variability and electronic offset, is indirectly related to the analyte concentration of
the sample. Transmittance measurements are converted to absorbance using the relationship:
absorbance = –log (transmittance).
System errors and factors that may interfere with sample result calculations are eliminated by
measuring light intensity at four locations of the reagent disc: the method-specific cuvette con-
taining test reagent, sample, and diluent; the sample blank cuvette containing sample blank
reagent, sample, and diluent (used in endpoint reactions, see below); the open cuvette, which
allows all the light to pass through; and the dark cuvette, which blocks the passage of light.
Light passing through a reaction cuvette is measured both at the wavelength that is absorbed by
the chromophore (I
) and at a wavelength not absorbed by the chromophore (I
λ1RC
λ2RC
). The
ratio of these two measurements corrects for cuvette optical quality and flash-to-flash variability
in the light source. The intensity of light transmitted through the open cuvette (I
λ 1OC
, I
λ 2OC
) is
measured at the same two wavelengths as the light transmitted through the reaction cuvette. A
correction for electronic offset is made at the same two wavelengths by measuring the residual
signal when the dark cuvette is in the optical path (I
λ 1
, I
).

This is the basic equation to measure analyte concentrations in the rate methods and endpoint
reactions used in chemistries.
Rate Methods
The rate of the reaction is calculated from the difference between absorbances measured at certain
defined intervals on the linear portion of the reaction curve. Absorbances are taken throughout the
read time to confirm the linearity of the reaction curve. The absorbance rates are converted to ana-
lyte concentrations by using the disc-specific calibration factors that are encoded on the bar code
ring.

Endpoint Reactions
Reagents, samples, and chromophores all absorb light in endpoint reactions. Light absorption by
the samples must be subtracted so that the analyte concentration can be isolated. The absorbance
of the sample is measured in a sample blank cuvette. Some chemistries employ a generic sample
blank and others (such as total bilirubin) use a dedicated sample blank. The intensity of the light
passing through the sample blank cuvette (I

Maintenance & Service
The piccolo xpress™ chemistry analyzer requires minimal maintenance.
Clean the exterior of the analyzer weekly with mild detergent and a soft,
damp cloth. The air filter requires cleaning twice per year. Regular main-
tenance of the analyzer will assure reliable operation.
CAUTION: Abaxis recommends only the cleaning methods
described in this section. If for some reason another
method is needed, contact Abaxis Technical Support
beforehand at 800-822-2947 to verify that the pro-
posed method will not damage the analyzer. Abaxis is
not responsible for damage caused by non-recom-
mended cleaning methods.
9.1 Cleaning the Analyzer
Clean the analyzer’s external case and display at least weekly.
Cleaning the Case
Clean the analyzer with a soft cloth, dampened with a mild, non-abrasive
detergent or cleaning solution, such as Simple Green®, a 10% bleach
solution, or a 30% isopropyl alcohol solution. Pre-soaked towelettes
(isopropyl alcohol) may be used as an alternate. Purchase isopropyl tow-
elettes from computer retailers.
Do not spray or pour any detergents, solutions or other liquids directly
onto the analyzer. Dampen a soft cloth or disposable paper towel with
the detergent, then apply to the analyzer.
Cleaning the Display
Clean the analyzer’s screen periodically using a soft, lint-free cloth
dampened with a glass-cleaning fluid or window cleaner. The screen can
be disinfected using a 10% bleach solution: apply the solution to a lint-
free cloth, then wipe the screen.
CAUTION: Do not use any cleaner containing alcohol. Do not
spray cleaner directly onto the display — dampen the
cloth instead.

found on the Internet at http://www.www.clsi.org.
9.3 Cleaning the Air Filter
The air filter in the back of the analyzer should be cleaned at least twice per year. Check the air fil-
ter more often than twice per year if the analyzer is located in an environment with excessive dust
or dirt.
To clean the air filter:
1. Unplug the analyzer and remove the power cord from the back of the analyzer.
2. Grasp the black mesh filter in the circular opening and remove it.
3. Wash the filter in warm soapy water and dry completely.
4. Place the clean, dry filter flat in the circular opening and push the sides of the filter behind
the edges of the circular opening.
5. Plug the power cord into the back of the analyzer.
6. Plug the power cord into the power source, and press the Power button on the front of the
analyzer. The analyzer will perform a diagnostic self test. It may take up to another four
minutes for the heaters to bring the analyzer disc chamber to operating temperature.
Refer to Section 7, “Troubleshooting” if the analyzer does not successfully pass the self test. See
Section 3.3 to run samples.

Computer/Printer
10.1 Connecting an External Printer
You can print results from the piccolo xpress™ chemistry analyzer using
any USB-compatible external printer approved by Abaxis. For a list of
approved printers, call Abaxis Technical Support at 800-822-2947.

10.2 Connecting a Computer
The piccolo xpress™ analyzer is equipped to transmit patient and con-
trol results in multiple formats to a computer through the analyzer’s
USB serial port. To receive the results from the piccolo xpress™, the
computer requires terminal emulation software (such as HyperTerminal,
included with Windows 95 and higher) and driver software to communi-
cate with the piccolo xpress™.
The results can be captured to a text file to be viewed with most word
processing, spreadsheet, and database applications. This section
describes the transmission specifications and hardware connections, and
using HyperTerminal to capture results to a text file.
Note: Data management systems can be interfaced with the
piccolo xpress™ to collect analysis results. Since the
installation for each type of data management system
differs, please contact your data management system
supplier for more information.

“mmo\L” is equivalent to “mmol/L” and “mmo\L” is “mmol/L” in the
transmitted results.

10.4 Installing the Abaxis® Driver
This section describes how to install a software driver that enables the piccolo xpress™ analyzer
to communicate with a Windows, Linux, or Macintosh computer. The analyzer installs on the
computer as a virtual communication port in the operating system.
Installing on a Windows PC
Installing the driver on a Windows PC requires the following:
■ piccolo xpress™ analyzer
■ PC with Windows 98, ME, 2000, or XP, and a USB port
■ Type A/Type B USB cable
■ Abaxis Driver CD
Note: Driver installation in Windows 2000 or XP requires a user account
with administrative privileges.
The screenshots in these instructions are from a typical Windows XP
Professional installation. Some of the items shown may vary slightly in
other versions of Windows.
Note: Do not connect the analyzer to the PC until instructed to do so.
Install the driver as follows.
1. Turn on the PC, and insert the Abaxis Driver CD into the PC’s CD-ROM drive.
2. Connect the USB cable to a Type A connector on the PC and to the uppermost USB con-
nector (Type B) on the back of the analyzer.
