Performing WBC counts and differentials helps diagnose diseases by analyzing WBC type variations. Blood smears are stained with Wright-Giemsa to differentiate WBC types. Elevated band-form neutrophils can signify an active infection.
Performing a white blood cell (WBC) count and differential is crucial in diagnosing various diseases as different conditions can affect the levels of different types of WBCs. This count provides valuable information on the relative percentages of different WBC types, aiding in the identification of specific health issues.
The preparation of blood smears for differentials involves staining the smears with Wright-Giemsa stain to visualize and differentiate the various white blood cell types. By examining these stained smears under a microscope, healthcare professionals can identify abnormalities and make informed diagnostic decisions.
For example, an increase in band-form neutrophils in a white blood cell count could indicate an active infection. Understanding these variations in WBC types and numbers is essential for accurate diagnosis and appropriate treatment.
