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