Lymphopenia is having a lower-than-normal level of lymphocytes in your blood. Lymphocytes are white blood cells that protect you from infection. Having too few of them can increase your chances of getting sick. You may or may not need treatment depending on your symptoms and what’s causing your lymphopenia.
Lymphocytopenia, also called lymphopenia, occurs when the lymphocyte count in your blood is lower than usual. Severe or chronic low counts can indicate a possible infection or other illness.
In adults, a normal lymphocyte count usually is between1,000 and 4,800 lymphocytes per microliter of blood. But your doctor may diagnose you with lymphopenia if you have fewer than 1,500 lymphocytes per microliter.
A normal white blood cell count is between 4,000 and 10,000 per microliter. About 30% to 40% of those — or 1,200 to 4,000 — will be lymphocytes. But don’t panic if your lab work shows much higher or lower concentrations than that.
Normal lymphocyte counts are generally between 1,000 and 4,800 cells per microliter of blood in adults and 3,000 to 9,500 cells per microliter in children. Your level of lymphocytes can be too low (lymphopenia) or too high (lymphocytosis).
Lymphocytopenia is an abnormally low number of lymphocytes (a type of white blood cell) in the blood. Many disorders can decrease the number of lymphocytes in the blood, but viral infections (including HIV infection) and undernutrition are the most common.
What does a low level of lymphocytes mean? Low levels of lymphocytes in your blood are called lymphocytopenia (or lymphopenia). The flu or other mild infections can cause lymphocytopenia, but it could also be caused by a more serious disease or condition, including: HIV or AIDs. Tuberculosis or typhoid fever. Viral hepatitis.
In adults, about 20% to 40% of the white blood cells in your body are lymphocytes. These cells help protect your body from infection. If you have low numbers of lymphocytes (lymphopenia), you are at higher risk of infection. The main risk factor for lymphopenia worldwide is poor nutrition.
What Is Low Lymphocyte Count? For adults, a lymphocyte count of less than 1000 cells per microliter of blood is considered a low number of lymphocytes in his blood. Lymphocytopenia or lymphopenia are alternate terms for low lymphocyte counts.
Lymphocytopenia refers to low levels of immune cells called lymphocytes in the blood. Discover the causes, symptoms, and treatment of lymphocytopenia here.
