1-4	Sysmex CA-50 Operator’s Manual -- Revised December 2000

INTRODUCTION

CAUTION 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 Chapter 10, Section 4.2: Built-In Printer Settings.

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.

Analysis Principles

Coagulation Method

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

INTRODUCTION

CAUTION 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 Chapter 10, Section 4.2: Built-In Printer Settings.

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.
