CALIBRATION
Sysmex SF-3000 Operator's Manual -- Revised September 1995 7-13
New compensation factor is calculated as follows:
New Compensation Factor =
Current comp. factor (%) x Avg. comp. factor (%)
100
The compensation calculation is not performed if the average compensation factor is
100.0%. Press [Quit] to return to the previous screen, permitting HGB/HCT Auto
program to resume.
NOTE: • The message "Cannot Execute Calibration" will be displayed and the
calibration values will not be updated if they are greater than the following
tolerances:
• Newly calculated compensation - Current compensation: 5%,
• Newly calculated compensation: 100 ± 20%
• If any average compensation factor exceeds 100±5% but the newly
calculated current compensation factor is within 100±20%, calibration can
only be updated using manual calibration. Refer to
Section 3
in this chapter.
(2) Re-analyze the samples designated for calibration. Confirm that the measured
values do not differ significantly from the reference values and that they are within
the allowable range.
If the HGB/HCT value is consistently higher or lower than the reference value,
recalibrate. If the difference continues to exceed the limits, check for sample
abnormalities such as coagulation problems, abnormal morphology, patient
medication, old blood samples, etc. If no sample abnormalities are discovered,
contact your Sysmex service representative.
