Calibration Procedures
Enter Factor Method
Section 6
2. If a mean value for each parameter based on at least 10 runs is not
automatically calculated by the reference hematology instrument or
hematology methods, use a calculator to determine the cumulative Reference
Mean for each parameter. For example:
The cumulative Reference WOC Mean is 7.15 when the WOC results from
each run are as follows:
• Sample 1 = 9.2, 9.1
• Sample 2 = 4.5, 4.6
• Sample 3 = 6.1, 5.9
• Sample 4 = 7.0, 7.3
• Sample 5 = 8.9, 8.9
The cumulative mean of 7.15 equals the sum of the values (71.5) divided by the 10
runs.
You may use the worksheet on the following page to record the values obtained
from running samples on a reference instrument. Make copies of the blank
worksheet as necessary.
NOTE:
Enter the WBC mean as the reference value for both the WOC and NOC.
