WHAT IS A NEUTROPHIL?

A neutrophil is a type of mature (developed) white blood that is present in the blood. A cell is the smallest, most basic of life, that is capable of existing by itself. White blood cells help protect the body against diseases and fight infections. Neutrophils are essential in protecting the body against disease and infections by removing and destroying some types of bacteria, wastes, foreign substances, and other cells. Neutrophils accomplish this by eating these substances. They are the main type of white blood cell that protect the body in this way.

WHERE ARE NEUTROPHILS MADE?

Neutrophils are made by the marrow (a tissue that fills the openings inside of bones). Neutrophils are sometimes made outside of the marrow as well. After the neutrophils are formed, they are released into the circulating blood.

WHAT PERCENT OF WHITE BLOOD CELLS ARE NEUTROPHILS?

Approximately 50% to 70% of white blood cells are neutrophils. Neutrophils are the most common type of white blood cell. The amount of neutrophils on blood work tests is known as the ANC (absolute neutrophil count). On most blood work tests, the ANC will be presented in terms of the amount of neutrophils per mm3 (cubic millimeters) of blood. The normal range for the neutrophil count is 1500 to 8000. It is important to keep in mind that the ranges mentioned above will be different depending on the machine used to do the blood test. Always use the normal range printed on the lab report to decide what range is normal.

Neutrophils are also essential for a process known as proteolysis, in which water is added to bonds that make up proteins so that they can be broken down into smaller substances. Proteins are extremely complex, naturally occurring substances made of amino acids that are essential to the body's structure and function.
