CLICK "Yes" to save the new calibration factors; CLICK "No" to abort the result.
Calibration may be verified by running appropriate commercial controls or by using fresh
whole blood samples that were analyzed on a reliably calibrated hematology analyzer or by
reference methodology. Test the new calibration factors either of the following ways.
Method one:
1. Prepare 3 to 5 normal fresh blood samples and run each one of them on a reference
analyzer at least 3 consecutive times. Calculate the mean (MEAN 1) and SD (SD 1) of
every sample.
2. Run the same samples on your analyzer for the same number of times and calculate the
mean (MEAN 2). The MEAN 2 should be within MEAN 1 ± 2SD. If any of the samples
fails to reach the criterion, call Mindray customers service department or your local
distributor.
Method two:
At the "Count" screen, run the calibrator at least 5 consecutive times and calculate the
means of the results. The means should be within the expected ranges supplied by the
manufacturer. If not, contact Mindray customer service department or your local distributor.
