RECEIVING INSTRUCTIONS
The CA-50 has been thoroughly tested before shipment, and has been packaged carefully
to prevent damage from shipping and handling. Reagents and options have also been sent
and will arrive accompanying the analyzer. Follow these guidelines when the system
arrives:
•Check to see that the arrows on the sides of the packages are pointing up. If the
arrows do not point up, record this information on the bill of lading.
•Visually inspect the outside of the package for rips, dents, or possible shipping
damage. Document any sign of damage on the bill of lading, regardless of how
insignificant it may appear. This is for your protection!
•Notify your service representative that the CA-50 system and its components have
arrived.
•Wait for your service representative to unpack the system and open the packages.

• In the event the instrument emits abnormal odor or any smoke, turn OFF the
ower immediately and disconnect the power plug from the wall socket.
If the instrument is used continuously in that state, there is a hazard that fire, electrical shock, or
injury may result.
Contact your Sysmex service representative for inspection.
• Take care not to spill blood or reagent, or drop wire staples or paper clips into the
instrument.
Those might cause short circuit or smoke emission. If such trouble should occur, turn OFF the
power immediately and disconnect the power plug from the wall socket. Then contact your Sysmex
service representative for inspection.
• Do not touch the electrical circuits inside the cover. Especially if your hands are
wet, there is a hazard that electrical shock may result.
• During an analysis, do not open the pipette guide and put in hands or fingers.
That could cause injury. When the pipette guide is opened during an analysis, an
alarm sounds and the operation stops.
• Always wear rubber gloves when performing maintenance work or inspection.
Use specified tools and parts.
After work is over, wash your hands with disinfectant.
There is a possibility that those areas of your hands which came in contact with blood could suffer
infection.
• Be careful when handling samples.
Always wear rubber gloves; otherwise infection by bacteria could result. If sample splash happened
to enter your eye or a cut, wash it off with plenty of water, and immediately see a physician.
When Handling Reagent
• If a reagent happens to enter your eye, wash it off immediately using plenty of
water, and take medical treatment at once.
• If you should swallow it inadvertently, call for a physician immediately, drink
lenty of water, and throw up.
• If it happens to adhere to your hands or skins, wash it off using plenty of water.
• When discarding used reaction tubes and instrument consumables, take proper
disposing steps as medical, infectious, and industrial wastes.
If they are contaminated with blood, infection of bacteria may result.
• Do not modify the instrument. Its modification is prohibited by Pharmaceutical
Affairs Law.

Power Supply, Connection, and Groundin
• Never put the power plug in any socket other than the AC 117, 220 or 240 V
socket.
Otherwise, fire or electrical shock will result.
• When installing the instrument, be sure to ground it.
Otherwise, fire or electrical shock will result.
Handling Power Supply Cord
• Take care not to damage the power cord, place a heavy device on it, or pull it
forcibly.
Otherwise, the wire may break causing fire or electrical shock.
• When connecting the instrument to a peripheral (host computer), be sure to
switch OFF the power beforehand.
Otherwise, electrical shock or instrument failure may result.

• Handle a reagent gently to prevent formation of bubbles.
• Take care not to spill a reagent. If it spills, wipe it off immediately using a wet
cloth or the like.
• Follow other instructions described on the Package Insert in each reagent.
Use of Instrument
• When performing maintenance work or inspection, use specified tools and parts.
Do not use substitute parts, or modify the instrument. It is hazardous.
• Those who have no or only limited experience in using instrument are
recommended to have guidance or assistance of those with sufficient
experience.
• If the instrument has developed a trouble by any chance, a person in charge of it
should take steps within the range specified in the OPERATOR’S MANUAL. As to
troubles other than mentioned, contact your Sysmex service representative for
assistance or service.
• Unpacking, installation, and confirmation of initial setup must be done by your
Sysmex service representative.
Environment for Use
• Install the instrument in a place which is not subject to water splash.
• Install the instrument in a place which is not subject to adverse effects of high
temperature, high humidity, dust, direct sunlight, strong lighting, etc.
• Do not give the instrument a strong vibration or impact.
• Do not install the instrument near a chemical storage or a place where a gas is
generated.
Recommended Pipette and Pipette Chip
• We recommended that you use the following pipettes and pipette chips to add
plasma and dispense/add reagents.
•Pipette:Eppendorf reference 4910 (50 - 200 µL)

Interpretation of APTT Abnormal Early Reaction.
• APTT results less than or equal to 20.0 seconds, APTT results with NC
(No Coagulation), SC (Slight Coagulation) or CCE (Coag. Curve Error)
error messages, or abnormally short APTT results may be caused by an
abnormal early reaction.
APTT results with an abnormal early reaction can be identified in the
analysis data.
• If an APTT result less than or equal to 20.0 seconds is obtained, the
following steps should be taken:
1. Verify sample and reagent integrity along with maintenance procedures.
2. Print out the Analysis data.
See Chapter 4, Section 4: OUTPUTTING ANALYSIS RESULT and
Note that the stored analysis results will be deleted, when you start a
next analysis on the same channel or you turn OFF the power or so
on.
3. Observe time in the “2%” position.
4. If that time is equal to or less than 15 seconds, then an abnormal early
reaction may have occurred.
5. Re-analyze the sample.
6. If result is the same, it should not be reported.
7. Review the previous patient history to determine acceptability of
patient results. Results of the other parameters considered, then make
overall evaluation.
8. Follow your laboratory's alternate protocol.
• An error code may or may not be associated with this result.
• An abnormal early reaction rarely occurs.
• The CA-50 should be set up so that any APTT results of less than or
equal to 20.0 seconds will have a message of <20.1 seconds on the printout.
• To set up this function see Chapter 10, Section 3.4: Report Limit Settings
and enter 20.1 for the APTT lower limit.
• Remember to change the Built-in Printer Settings back to “List” after review
of the analysis data.

INTRODUCTION
11 . INSTRUMENT SPECIFICATIONS
Analysis parameters/Calculation parameters
See Section 4: ANALYSIS PARAMETERS AND CALCULATION PARAMETERS in this
chapter.
1.Coagulation Reaction Detection Method (Scattered Light Detection Method)
Irradiates red light (660 nm) onto a mixture of blood plasma and reagent and detects the
change in turbidity (when the fibrin clots are formed) as the change in scattered light. And
measures the coagulation time.
2.Coagulation Point Detection Method (Percentage Detection Method)
Calculates the coagulation time as the time required to achieve the amount of scattered light
that is set for the coagulation detection point, using the amount of scattered light that is
present just after the start of detection as 0%, and the amount of scattered light that is
present at the completion of coagulation as 100%.
Range of Analysis
Fibrinogen Concentration
Can analyze from 50 mg/dL to 450 mg/dL.
Detection Time
Detects within the maximum detection time, and measures the result.
Typical maximum detection time: 100 seconds for PT and Fbg; 190 seconds for others.
Maximum detection time: 600 seconds for each parameter
