What are POLYS in a blood test result?

POLYS in a blood test result stands for polymorphonuclear cells, which are a type of white blood cell. They are also commonly referred to as neutrophils. Neutrophils are the most abundant type of white blood cell, making up 50-70% of all circulating white blood cells.

Neutrophils play a crucial role in the body's immune system by defending against bacterial and fungal infections. They are phagocytic cells, which means they can engulf and destroy foreign particles, bacteria, and damaged tissues. Neutrophils are also involved in the inflammatory response and help to clear away dead cells and debris from the site of injury or infection.

The absolute neutrophil count (ANC) is a measure of the total number of neutrophils in a sample of blood. It is reported as part of a complete blood count (CBC), a common blood test that provides information about the different types of blood cells in the body.

Normal ANC values may vary slightly between laboratories, but generally, the reference range is as follows:

- Adults: 1,500-8,000 neutrophils per microliter (μL) of blood

- Children: 1,500-10,000 neutrophils per μL of blood

An increased neutrophil count, or neutrophilia, may occur in response to an infection, inflammation, or tissue damage. It can also be caused by certain medications, such as corticosteroids, and by conditions that affect the bone marrow, where neutrophils are produced.

On the other hand, a decreased neutrophil count, or neutropenia, can be caused by a variety of factors, including infections, autoimmune diseases, chemotherapy, radiation therapy, and certain genetic disorders.

If your blood test result shows abnormal neutrophil levels, your doctor will evaluate the results in the context of your overall health and symptoms to determine the cause and recommend appropriate treatment or further testing.
