Absolute Lymphocyte Count
What is Absolute Lymphocyte Count?
An Absolute Lymphocyte Count test is used to measure the level of white blood cells (Lymphocytes) in the blood. White blood cells are formed in the bone marrow. These are the armies that are a part of the immune system and protect the body from infection. A change in the level of lymphocytes could be due to an infection, during or after an illness. Conditions such as bacterial infections, viral infections, autoimmune disorders, and cancer cause abnormalities in the level of lymphocytes.
The normal range for lymphocytes is 4,500 to 11,000 WBC (White Blood Cells) per microliter. WBC count higher than the normal range could point to either an infection or a disease. A count lower than the normal range could indicate vitamin deficiencies, lupus, or rheumatoid arthritis.
