Absolute vs relative lymphocyte count
How do you calculate absolute lymphocyte count?
To get the Absolute lymphocytes number, multiply the WBC by the percent lymphocytes. For example, if the WBC is 30.0, and the lymphocyte percent is 65%, the absolute lymphocyte number is 30.0 X 0.65 = 19.5.
What is normal range for absolute lymphocyte count?
Lymphocyte levels can change according to a person’s race, gender, location, and lifestyle habits. The normal lymphocyte range in adults is between 1,000 and 4,800 lymphocytes in 1 microliter (µL) of blood. In children, the normal range is between 3,000 and 9,500 lymphocytes in 1 µL of blood.
What does a high absolute lymphocyte count mean?
A high level of lymphocytes may be an indication of lymphocytosis, which is associated with inflammatory bowel disease. Lymphocyte counts above the normal range can be a harmless and temporary situation due to the body’s normal response to an infection or inflammatory condition.
What does a high absolute lymph count mean?
An increase in lymphocyte concentration is usually a sign of a viral infection (in some rare case, leukemias are found through an abnormally raised lymphocyte count in an otherwise normal person). A high lymphocyte count with a low neutrophil count might be caused by lymphoma.
