“White blood cells (WBCs) in our body help fight infections. There are various types of WBCs and each has its own way of fighting microbial infections. The most important WBC is called the neutrophil.
“The number of neutrophils in the blood is expressed as absolute neutrophil count (ANC) and it measures the percentage of neutrophils in the differential WBC count. The ANC of a healthy individual falls in the range of 2,500 to 6,000 per microliter.
“A total blood count gives the levels of the three types of blood cells – white blood cells, red blood cells, and platelets. Neutrophils are present in two forms – polys and bands. Polys are also known as segmented neutrophils and are the most abundant of the WBCs. Bands are also called stabs and are immature polys. Both polys and bands destroy invaders (i.e. microbes) in the body.”
