<unk>  <unk>  is a measure of the number of<unk>  granulocytes (also known as polymorphonuclear cells, PMN's, polys, granulocytes, segmented<unk> s or segs) present in the blood.<unk> s are a type of white blood cell that fights against infection. A deficiency of<unk> s, known as neutropenia, may increase chances of infection.
The<unk>  is calculated from measurements of the total number of white blood cells (WBC) and the numbers of<unk> s and bands, which form a subset of the total number of white blood cells.  A normal<unk>  is above 1,500.  An<unk>  less than 500 is defined as neutropenia and significantly increases the risk of infection.  Neutropenia is the condition of a low<unk> , and the most common condition where an<unk>  would be measured is in the setting of chemotherapy for cancer.
