For the accurate WBC concentration calculation, you need to calibrate the app.

Steps for 100x:

  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. 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.
