Absolute Neutrophil Count

An Absolute Neutrophil Count test measures the percentage of neutrophil type of white blood cells (WBCs). This test helps identify conditions that may affect the WBC count, such as infections, inflammations, bone marrow disorders, etc., and monitor their treatments. It is often done as part of a complete blood count test that also measures other types of blood cells.

Neutrophils are the key indicator of an individual’s immune system function and are responsible for fighting-off bacterial infections. These are the first cells to arrive at the site of an infection. 

An ANC test helps monitor the immune response in individuals undergoing cancer treatments that can affect bone marrow’s capacity to produce WBCs, such as chemotherapy or radiation therapy. A low ANC level may indicate the risk of infections and necessitates the need for prompt medical intervention. Whereas, a high ANC level may indicate serious conditions such as leukemia, other blood disorders, etc., and requires the need for an appropriate course of treatment, which will depend on the underlying cause of the elevated ANC levels. No special preparation is required for an ANC test; eat or drink as per your daily routine. 

Test result ranges are approximate and may differ slightly between different labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. The results will help them determine your medical condition and formulate an overall treatment plan.
