For the accurate WBC concentration calculation, you need to calibrate the app.
Steps for 100x:
  1. 1.
    Make a CBC test (100x) on the monolayer area of the reference slide where you know the WBC concentration (it will be X).
  2. 2.
    Go to the test results page -> report and check the calculated WBC concentration (it will be Y).
Calculated WBC concentration
3. Calculate correction coefficient K using the formula:
K = X/Y
4. Go to the page and enter the calculated value for 100x.
Make the same steps for 40x.
