CHAPTER 8 Calibration
Sysmex XE-5000 Instructions for Use 8-5
Revised April 2007
When the Calibration Error message is displayed, select
“OK” on the function menu to return the system to the
last screen. The automatic calibration can be continued.
2. Reanalyze the sample used for the calibration using the
XE-5000. Confirm that the analysis value is within the
allowable range and does not vary greatly from the
reference value.
Recalibrate if HGB and HCT values are consistently
higher or lower overall than the reference value. If, after
re-calibration, the analysis values are still outside the
allowable range, or if abnormal data is found, check the
samples for abnormalities such as abnormal blood
coagulation, blood cell morphology, patient medicinal use
and old blood. If no abnormality is found on the samples,
contact your Sysmex technical representative.
Note:
• Comp. [%] in the right of the screen is calculated as
follows:
• The new compensation rate is calculated as follows:
• When the new compensation rate exceeds the
following allowable range, the Calibration Error
message will appear, and the compensation rate will
not be updated.
New compensation rate ≥ 120%
New compensation rate ≤ 80%
New compensation rate - Current compensation rate
≥ ±5%
• Manual calibration can be carried out when the
difference between the new compensation rate and
the current compensation rate exceeds ±5%, but the
new compensation rate is within 100±20%.
