What Are Normal Lymphocyte Ranges?

A lymphocyte count between 1,000 and 4,800 per microliter of blood is considered normal for adults, while a count between 3,000 and 9,500 lymphocytes per microliter of blood is healthy for children, states the National Heart, Lung and Blood Institute. Lymphocytes are white blood cells.

A count of less than 1,000 lymphocytes per microliter of blood in adults, or less than 3,000 lymphocytes per microliter of blood in children, is known as lymphocytopenia, or lymphopenia, says the National Heart, Lung and Blood Institute. If an adult has a lymphocyte count significantly higher than 3,000 per microliter of blood, he has lymphocytosis. The threshold for lymphocytosis in children depends on the age of the child, but in some cases, it is as high as 7,000 to 9,000 lymphocytes per microliter of blood, explains Mayo Clinic.
