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.
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 100 white blood cells using 100x 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 single layer of cells.
Tap the test configuration button: set "Blood: WBC differential" test type, choose a patient.
Tap the app settings button. Set the cell number to analyze (100 by default). Start the test.
Move your slide, controlling the focus. The App will detect and count white blood cells. After reaching the specified number of cells, the application will complete the test.
Go to the Cells tab to check the pre-classification. Drag the cells to the appropriate type to correct errors.
Confirm the test using the Approve button. On the report page, you can download the final PDF report.
