What is a normal lymphocytes percentage?

Normal lymphocyte percentage

- Adults: 20% - 40% of total white blood cell count

- Children: 30% - 70% of total white blood cell count

Lymphocytes are a type of white blood cell that play a vital role in the body's immune system. They are responsible for recognizing and attacking foreign invaders, such as bacteria and viruses. Lymphocytes are also involved in the production of antibodies, which are proteins that help to protect the body against infection.

The percentage of lymphocytes in the total white blood cell count can vary depending on a number of factors, including age, sex, and overall health. However, a normal lymphocyte percentage is typically between 20% and 40% for adults and between 30% and 70% for children.

A higher than normal lymphocyte percentage may indicate an infection, inflammation, or other immune system disorder. A lower than normal lymphocyte percentage may be a sign of a bone marrow disorder, such as leukemia or lymphoma.

If you have any concerns about your lymphocyte percentage, talk to your doctor. They can order additional tests to determine the cause of any abnormal results.
