Absolute neutrophil count (ANC) is a measure of the number of neutrophil granulocytes [1] (also known as polymorphonuclear cells, PMN's, polys, granulocytes, segmented neutrophils or segs) present in the blood. Neutrophils are a type of white blood cell that fights against infection.
The stated normal range for human blood counts varies between laboratories, but a neutrophil count of 2.5–7.5 × 10 9 /L is a standard normal range. People of African and Middle Eastern descent may have lower counts, which are still normal. [17] A report may divide neutrophils into segmented neutrophils and bands.
A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...
Generally accepted reference range for absolute neutrophil count (ANC) in adults is 1500 to 8000 cells per microliter (μL) of blood. Three general guidelines are used to classify the severity of neutropenia based on the ANC (expressed below in cells/μL): [42] Mild neutropenia (1000 <= ANC < 1500): minimal risk of infection
During the condition, which lasts for three to six days and tends to occur approximately every three weeks (but can range from 14 to 36 days), [2] [3] the absolute neutrophil count (ANC) is less than 200-500 cells/μL (<0.2-0.5x10 9 /L), with increase of monocyte counts, and mild oscillations of other cells, including a mild anemia.
The absolute neutrophil count in this test will be below 500, and can reach 0 cells/mm 3. Other kinds of blood cells are typically present in normal numbers. Other kinds of blood cells are typically present in normal numbers.
Exceptions are mainly those values that denote total blood concentration, and in this article they are: [3] All values in Hematology – red blood cells (except hemoglobin in plasma) All values in Hematology – white blood cells; Platelet count (Plt) A few values are for inside red blood cells only: Vitamin B 9 (folic acid/folate) in red blood ...
Febrile neutropenia or neutropenic fever is a defined as a single oral temperature value of ≥ 38.3 C (101 F) or a temperature ≥ 38 C (100.4 F) for ≥ 1 hour, with an absolute neutrophil count (ANC) < 1500 cell/microliter. [1] In case of severe neutropenia, the ANC is < 500 cell/microliter. [1]
