Using the Calibration Programs
9-18
mentioned in the formula above) is 8.4 and the current whole blood calibration factor is 98.9
％
, analyze this calibrator in the whole blood mode for ten times
（
n=10
）
and the results are
8.1, 8.0, 8.1, 8.1, 8.3, 8.3, 8.2, 8.0, 8.1, 8.3, CV=1.5%, Mean=8.16
。
Since the calculated CV meets the requirement of Table 9-1, the mean value, 8.12, is valid
and the new calibration factor can be calculated as follows:
The calculated new calibration factor should be within 75 ％ to 125 ％ . If not, try to find out the
reason and if necessary, call Mindray customer service department or your distributor for
assistance.
If the reproducibility of the calibrated parameter does not meet the requirements of Table 9-1,
you must try to find out the reason and re-run the calibrator after you have solved the problem.
If necessary, contact Mindray customer service department or your local distributor for
assistance.
