Blood: CBC test
A complete blood count (CBC) is a laboratory test that indicates the counts of white blood cells, red blood cells, and platelets.
A white blood cell differential is a laboratory test that provides information about the types and amounts of white blood cells in the sample. The test measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils, and basophils – as well as abnormal cells if they are present.
White blood cells
Microscopist examines the smear in a systematic pattern, scanning from side to side within the feathered edge (single layer of cells at the end of the smear) and counting cells consecutively. Microscopist counts at least 100 white blood cells using 100x or 40x objective lens magnification.

Preparation
Put the sample, turn on the light, use 40x or 100x objective lens magnification, and set the lens focus. Move the field of view to the single layer of cells.
The app supports 40× dry or 100× oil-immersion objective lens
Test execution
Open the test configuration panel: set "Blood: CBC" test type, choose a patient. Start the test.
Move your slide, controlling the focus. The app will automatically detect and count white blood cells. After reaching 100 cells (you can change the number on the Settings panel), the application will complete the test.
Celly.AI automatically detects and counts white blood cells
If a cell was not detected, hold it with your finger for a few seconds
Result review and confirmation
- Go to the Cells tab, choose the cell type (WBC/RBC/PLT) to check the pre-classification. Drag the cells to the appropriate type to correct errors. Confirm the test using the Approve button.
Use the hotkeys for the fast class correction: hover over the cell and press the hotkey button - the cell will immediately change the class
Move the artifacts and blurred cells to Unclassified type - this type is not involved in the cells ratio calculation
Cells Page
- On the Snapshots page, you can review the photos. The application automatically captures 10 photos during the test. You can find here your snapshots too.

- On the Report page, you can review and download the final PDF report with the following sections:
- WBC-differential, which includes total WBC concentration (check the calibration page for accurate calculation), reference ranges, and abnormality flags.
- RBC distribution by Size, Shape, Color, and Inclusions

If your integration with LIS is enabled you'll get the reports directly to your LIS
