Figure 9-15 A message box to confirm the new calibration factors
CLICK ”Enter” to save the new calibration factors to the “Manual Calibration” screen and
enter the “Count” screen.
Test the new calibration factors either of the following ways.
Method one:
Prepare 3-5 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.
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 sample 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.
