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.
Put the sample, turn on the light, use 100x objective lens magnification, and set the lens focus. Move the field of view to the monolayer of cells.
Open the test configuration panel: set "Blood: CBC" test type. 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.

- On the Snapshots page, you can review the photos. The application automatically captures 10 photos during the test. You can find here your manual snapshots too.
- On the Report page, you can review and download the final PDF report with the following sections:
- RBC distribution by Size, Shape, Color, and Inclusions
