2. Working conditions
2.1. Environment
The Pentra 80 should be operated in an indoor location only. Operation at an altitude over 3000
meters (9800 feet) is not recommended. Instrument is designed to be safe for transient voltages
according to INSTALLATION CATEGORY II and POLLUTION DEGREE 2.
Please ask your ABX Diagnostics representative service center for any information about the operating
location when it does not comply with the recommended specifications.
2.2. Location
The Pentra 80 should be placed on a clean and leveled table or work station. Please note that the
Pentra 80, printer and reagents weigh approximately 40 kilograms (88 lbs). Avoid exposure to sunlight.
Proper ventilation requires that a space of at least 20 cm (8 inches) must be left behind the instrument.
2.3. Grounding
INTRODUCTION
Proper grounding is required. Check that the wall ground (earth) plug is correctly connected to the
laboratory grounding electricity installation.
If there is no ground then use a ground stake. Current electricity Standards must be applied.
2.4. Humidity and temperature conditions
The Pentra 80 must function between 16 to 34°C (61 to 93°F). Maximum relative humidity 80% for
temperatures up to 31°C (88°F) decreasing linearly to 50% relative humidity at 40°C (104°F). If it is kept
at a temperature of less than 10°C (50°F), the instrument should be allowed to sit for an hour at the
correct room temperature before use.
2.5. Electromagnetic environment check
The Pentra 80 as been designed to produce less than the required level of electromagnetic
interferences in order to operate in conformity with its destination. The electromagnetic interferences
caused by the Pentra 80 are limited to a level allowing the correct operation of other instruments in
conformity with their destination.
In case of problems, check that the instrument is not placed in proximity of electromagnetic fields,
or short wave emissions (radars, X-rays, scanner, etc...).
2.6. Environment protection
Used accessories and consumables must be collected by a laboratory specialized in elimination
and recycling of this kind of material according to the legislation.

when neutralizing and disposing of waste.
5. Limitations
5.1. Maintenance
In Chapter 8. Maintenance, specific maintenance procedures are listed. The maintenance
procedures identified are mandatory for proper use and operation of the ABX PENTRA 80.
Failure to execute any of these recommended procedures may result in poor reliability of the
system.
5.2. Blood specimens
Verification of any abnormal test result (including flagged results or results outside of the normal
range) should be performed using reference methods or other standard laboratory procedures for
conclusive verification of the results. The sections below list known limitations of automated blood cell
counters which use the principles of impedance and light absorbance as principles of measurement.
5.3. Known interfering substances
WBC:
• White Blood Cells (Leukocytes):WBC results that exceed the linearity limits of the system will
require dilution of the blood sample (Leukemia sample followed by a leukopenia). Re-assaying the
diluted sample will help to obtain the correct assay value.
• Unlysed Red Cells - In some rare instances, the erythrocytes in the blood sample may not be
completely lysed. These non-lysed red blood cells may be detected on the WBC histogram with an
L1 alarm or as an elevated baseline on the side (leading edge) of the lymphocytes population. Non-
lysed erythrocytes will cause a falsely elevated WBC count.
• Multiple myeloma - The precipitation of proteins in multiple myeloma patients may give high
WBC counts.
• Leukemia - A very low WBC count may result from this disease because of possible increased
fragility of the leukocytes leading to destruction of some of these cells during counting. These white
cell fragments will also interfere with the white cell differential parameters.
• Chemotherapy - Cytotoxic and immunosuppressive drugs may increase the fragility of the
leukocytes which may cause low WBC counts.
• Cryoglobulins - Increased levels of cryoglobulin that may be associated with myeloma,
carcinoma, leukemia, macroglobulinemia, lymphoproliferative disorders, metastic tumors,
autoimmune disorders, infections, aneurism, pregnancy, thromboembolic phenomena, diabetes,
etc, which can increase the WBC, RBC or Plt counts and the Hgb concentration. The specimen
must be warmed up to 37°C (99°F) in a bain marie for 30 minutes and analyzed again immediately
after (analyzer or manual method).
• Macrothrombocytes - in excessive numbers may affect and increase Leukocyte numeration.
8/10
SECTION 1 SPECIFICATIONS
RBC:
• Red Blood Cells (Erythrocytes): The red blood cell dilution contains all the formed elements in
the blood: erythrocytes, leukocytes and platelets. During erythrocytes counting (red blood cells),
platelets are not counted as their size falls below the minimum threshold.
• Agglutinated erythrocytes - May cause a low incorrect RBC count. Blood samples containing
the agglutinated red blood cells may be suspected by elevated MCH and MCHC values and shown
by examination of the stained blood film.
• Cold agglutinins - IgM immunoglobulins which are high in cold agglutinin disease may cause
lower RBC and Plt counts and increase MCV.
Hgb (Hemoglobin):
• Turbidity of the blood sample - Any number of physiological and/or therapeutic factors may
produce high incorrect Hgb results. To obtain accurate hemoglobin results when increased turbidity
of the blood sample occurs, determine the cause of the turbidity and follow the appropriate method
below:
• High WBC: An extremely high WBC will cause excessive light scatter. In these cases use
reference (manual) methods.The diluted sample should be centrifuged, and the supernatant fluid
measured with a spectrophotometer.
• High lipid concentration: A high concentration of lipids in the blood sample will give the plasma
a «milky» appearance. This condition can occur with hyperlipidemia, hyperproteinemia (as in
gammapathies) and hyperbilirubinemia. Accurate hemoglobin determinations can be achieved by
using reference (manual) methods and a plasma blank.
• Increased turbidity may also be seen in cases where the red blood cells are resistant to lysing.
This condition will cause an incorrect high Hgb result, but may be detected by observing the
abnormal MCH, MCHC values, and the increased baseline on the leading edge of the WBC
histogram. Erroneous hemoglobin results will cause the results of the MCH and MCHC to be
incorrect as well.
• Fetal bloods - The mixing of fetal and maternal bloods may produce a high inaccurate Hgb value.
Hct (Hematocrit):
• Red blood cells agglutination - May produce an inaccurate Hct and MCV values. Red blood cell
agglutination may be detected by observing abnormal MCH and MCHC values, as well as by
examination of the stained blood film In such cases, manual methods may be required to obtain an
accurate Hct value
MCV (Mean Corpuscular Volume):
• Red blood cell agglutination - May produce an inaccurate MCV value. Red blood cell
agglutination may be detected by observing abnormal MCH and MCHC values, as well as by
examination of the stained blood film. In such cases, manual methods may be required to obtain an
accurate MCV value.
• Excessive numbers of large platelets and/or the presence of an excessively high WBC count
may interfere with the accurate determination of the MCV value. In such cases, careful examination
of the stained blood film may reveal the error.
MCH (Mean Corpuscular Hemoglobin):
• The MCH is determined according to Hgb value and the RBC count. The limitations listed for the
Hgb and RBC will have an effect on the MCH and may cause inaccurate values.
MCHC (Mean Corpuscular Hemoglobin Concentration):
• The MCHC is determined according to the Hgb and Hct values. The limitations listed for the Hgb
and Hct will have an effect on the MCHC and may cause inaccurate values.
RDW (Red blood cell Distribution Width):
• The red blood cell distribution width is determined according to the RBC count.
• Nutritional deficiency or blood transfusion - May cause high RDW results due to iron and/or
cobalamin and /or folate deficiency.
Plt (Platelets):
• Very small erythrocytes (microcytes), erythrocyte fragments (schizocytes) and WBC fragments
may interfere with the proper counting of platelets and cause elevated Plt counts.
• Agglutinated erythrocytes - May trap platelets, causing an erroneously low platelet count. The
presence of agglutinated erythrocytes may be detected by observation of abnormal MCH and
MCHC values and by careful examination of the stained blood film.
• Giant platelets in excessive numbers - may cause a low inaccurate platelet count as these large
9/10
PENTRA 80 TECHNICAL MANUAL RAA022AA
platelets may exceed the upper threshold for the platelet parameter and are not counted.
• Chemotherapy - Cytotoxic and immunosuppressive drugs may increase the fragility of these
cells which may cause low Plt counts. Reference (manual) methods may be necessary to obtain an
accurate platelet count.
• Hemolysis - Hemolysed specimens contain red cell stroma which may increase platelet counts.
• A.C.D. blood - Blood anticoagulated with acid-citrate-dextrose may contain clumped platelet
which could decrease the platelet count.
• Platelet agglutination - Clumped platelets may cause a decreased platelet count and/or a high
WBC count. The specimen should be recollected in sodium citrate anticoagulant to ensure the
anticoagulated character depending on agglutination and reanalyzed only for the platelet count.
The final Plt result must be corrected for the sodium citrate dilution effect. However, these platelet
clumps do trigger flags L1, LL and LL1.
MPV (Mean Platelet Volume):
• Giant platelets that exceed the upper threshold of the Platelet parameter may not be counted as
platelets. Consequently, these larger platelets will not be included in the instrument’s calculation of
Mean Platelet Volume.
• Very small erythrocytes (microcytes), erythrocytic fragments (Schizocytes) and white blood cell
fragments may interfere with the proper counting and sizing of Platelets.
• Agglutinated erythrocytes - May trap Platelets, causing an incorrect MPV result. The presence
of agglutinated erythrocytes may be detected by observation of abnormal MCH and MCHC values
and by careful examination of the stained blood film.
• Chemotherapy - May also affect the sizing of Plts.
Blood samples collected in EDTA will not maintain a stable Mean Platelet Volume. Platelets
collected in EDTA swell depending on the time post-collection and storage temperature.
LYM# (Lymphocyte count absolute value), LYM% (Lymphocyte percentage):
• The Lymphocyte count is derived from the WBC count. The presence of erythroblasts, certain
parasites and erythrocytes that are resistant to lysis may interfere with an accurate LYM count.
Limitations listed for the WBC count pertain to the LYM # and % counts as well.
MON# (mononuclear cell count absolute), MON% (Mononuclear percentage):
• The mononuclear cell count absolute is derived from the WBC count. The presence of large
lymphocytes, atypical lymphocytes, blasts and an excessive number of basophils may interfere
with an accurate monocyte count.
• Limitations listed for the WBC count pertain to the MON # and % counts as well.
NEU# (neutrophil count absolute), NEU% (Neutrophil percentage):
• The neutrophils cell count is derived from the WBC cell count. The excessive presence of
eosinophils, metamyelocytes, myelocytes, promyelocytes, blasts and plasma cells may interfere
with an accurate neutrophils count.
EOS# (Eosinophil cell count absolute), EOS% (Eosinophil percentage):
• The eosinophil cell count is derived from the WBC cell count. The presence of abnormal granules
(degranulated areas, toxic granules...) may interfere with the eosinophil counting.
BAS# (Basophil cell count absolute), BAS% (Basophil percentage):
• The Basophil cell count is derived from the WBC cell count.
