753-4Neutrophils [#/volume] in Blood by Manual countActive

Term Description

The total number of neutrophilic white blood cells quantitated first by performing a manual hemocytometer count for the white blood cell count, then quantitating the percentage of neutrophils from a peripheral smear. The absolute neutrophil count is determined by multiplying the total white blood cell count by the percentage of neutrophils counted on the peripheral smear.

Part Description

LP14267-6   Neutrophils
Neutrophils are the most common form of white blood cells in healthy adults. Neutrophils are approximately 13 micrometers in diameter and have segmented nuclei with 3-5 lobes that are connected by thin strands of chromatin. (Practical Haematology; Barbara J. Bain, Imelda Bates, Mike A. Laffan,S. Mitchell Lewis; Eleventh edition; 2012) Neutrophils function to fight infection by both engulfing microorganisms and secreting lethal enzymes.
(https://www.ncbi.nlm.nih.gov/pubmedhealth/PMHT0022058/) They are produced in the bone marrow and their primary function is to fight infection. Neutrophil numbers increase in the blood in response to acute bacterial infection, inflammation, necrosis or chronic myelogenous leukemia. Neutrophil levels are decreased in the following conditions: aplastic anemia, autoimmune disorder, cancer, chemotherapy, myelodysplastic syndrome and during a negative reaction to drugs.
