Absolute Lymphocyte Count Test

The absolute Lymphocyte Count test is performed on a sample of blood to measure the level of Absolute Lymphocyte Count in the blood. Lymphocytes are one of the several different types of white blood cells. White blood cells are an important part of your immune system. They help your body fight antigens, like bacteria, viruses and other toxins that make you sick. If you have a weak immune system, it means that there are not enough white cells in your bloodstream. The test is performed to detect Infectious Mononucleosis, Leukemia, Lymphoma, and tuberculosis.

No special preparation is needed for the Absolute Lymphocyte Count. You are advised to inform the doctor if you are on medications or any prevailing medical conditions or allergies which can alter the test results. You are advised to wear a sleeveless shirt or a full sleeve shirt with a loose fit which can be comfortable while giving the blood sample.

A low lymphocyte count, called lymphocytopenia, usually occurs because:
your body isn’t producing enough lymphocytes
lymphocytes are being destroyed
lymphocytes are trapped in your spleen or lymph nodes
Other conditions that can cause lymphocytopenia include:
Malnourished
HIV and AIDS
influenza
autoimmune conditions, such as lupus
some cancers, including lymphocytic anemia, lymphoma, and Hodgkin disease
steroid use
radiation therapy
certain drugs, including chemotherapy drugs
