Final answer:
The ANC (Absolute Neutrophil Count) is a calculation used to determine the number of active neutrophils in the blood. It is calculated by adding the percentage of neutrophils (also known as polys or bands) to the white blood cell count (WBC) and multiplying the sum by the WBC. Neutrophils are a type of white blood cell that plays a critical role in the body's immune response to infection.
Step-by-step explanation:
The ANC (Absolute Neutrophil Count) is a calculation used to determine the number of active neutrophils in the blood. It is calculated by adding the percentage of neutrophils (also known as polys or bands) to the white blood cell count (WBC) and multiplying the sum by the WBC. For example, if the WBC is 2.1 and the sum of polys and bands is 26, the ANC would be 546.
Neutrophils are a type of white blood cell that plays a critical role in the body's immune response to infection. They are the most common type of leukocyte and are responsible for attacking and destroying bacteria. In a CBC (Complete Blood Count) test, neutrophils can be identified by various names, including polys, PMNs, granulocytes, segmented neutrophils, or segs.
