What is the normal range for lymphocytes in the blood?

Lymphocytes are a type of white blood cell that play a crucial role in the immune system, aiding in the body’s defense against infections and diseases. The normal range for lymphocytes in a healthy adult typically falls between 1,500 to 3,000 x 10^6/L. This range signifies the average amount of lymphocytes present in a liter of blood under normal physiological conditions.

A count below this range may indicate a compromised immune system or certain medical conditions, while counts above it may suggest an active infection or other immune responses. Recognizing the normal range is essential for healthcare professionals to assess patients accurately and to make informed decisions about further testing or treatment options based on individual lymphocyte counts. Understanding these values can help in the interpretation of lab results and lead to timely patient care.
