Ans: A doctor needs an ANC(absolute neutrophil count) test to analyse if the count is low or high. This test is usually done as a part of a CBC(Complete blood count) test; this test reports how many of each type of white blood cell is present in your blood, whereas ANC deciphers how many neutrophils are in your blood. In addition, it indicates the levels of neutrophils to help doctors recommend medications and treatments for the concerned patients.
