Lymphocytes

Lymphocytes are white blood cells that play a role in fighting disease. They are present in the lymphoid tissue and the blood. The spleen, bone marrow, and lymph nodes produce lymphocytes. Chronic lymphocytic leukemia is a form of cancer that starts in the white blood cells that become lymphocytes. This article takes a look at how chronic lymphocytic leukemia affects the levels of these cells and what that might mean for a person’s outlook. Share on Pinterest Martynasfoto/Getty Images Not all individuals with chronic lymphocytic leukemia have symptoms. In some cases, the disease progresses slowly before symptoms develop. Due to this, doctors partly base the diagnosis of chronic lymphocytic leukemia on the level of There are two main types of lymphocytes: T cells and B cells. Both types of lymphocytes are part of the immune system and help the body fight viruses, bacteria, and other pathogens. The classification of chronic lymphocytic leukemia depends on the type of lymphocyte affected. The two main forms are B-cell chronic lymphocytic leukemia and T-cell prolymphocytic leukemia. B-cell chronic lymphocytic leukemia affects the B cells and is the A normal lymphocyte range for adults is anywhere between When someone develops chronic lymphocytic leukemia, they have a higher level of lymphocytes. However, these cells do not work as they should, so they do not fight infection properly. Although a lymphocyte level of greater than or equal to 5,000 B cells helps doctors make a dia...

Lymphocytes are white blood cells that help the body fight infection and disease. The normal range for an adult is between 1,000 and 4,800 lymphocytes per microliter (µL) of blood. The immune system is a complex network of cells known as immune cells that include lymphocytes. These cells work together to defend the body against foreign substances, such as bacteria, viruses, and cancer cells that can threaten its functioning. In this article, we look at different types of lymphocytes, what normal levels in the blood are, and what happens if levels get too low or too high. 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. Causes A high level of lymphocytes can also be a sign of People with lymphocytosis may experience symptoms depending on what is causing this spike in lymphocytes. Some possible causes of lymphocytosis include: • viral infections, such as • bacterial infections, such as Bartonella henselae • parasitic infections, such as Toxoplasma • mycobacterial • cancer, such as • drug reactions • stress A doctor may perform a variety of tests to diagnose the underlying cause of lymphocytosis. They will check an individual’s symptoms and medical history. Doctors may order additional diagnostic tests, such as blood tests or medical imaging scans, to confirm the cause. How to lower levels Lymphocyte levels may return to normal on their own or following treatment. D...
