Lymphocytes are white blood cells that help to protect the body from infections. Lymphocytopenia, or lymphopenia, is a condition in which a person does not have enough lymphocytes in their blood.
Lymphocytopenia refers to a lack of lymphocytes in the bloodstream. The usual range of blood lymphocyte levels differs for adults and children.
For adults, lymphocytopenia occurs when the total number of lymphocytes per microliter of blood falls below 1,000Trusted Source. For children, lymphocytopenia occurs when this number falls below 3,000Trusted Source.
There are three main factors that can cause a drop in lymphocyte levels. These are:
slow production of lymphocytes
excessive destruction of lymphocytes
capture of lymphocytes by the spleen or lymph nodes while filtering the blood
In many cases, there are no noticeable symptoms of lymphocytopenia. Many people only discover that they have the disorder during tests for other conditions.
When symptoms do develop, they may include:
fever
cough
runny nose
skin rash
infections that do not get better
swelling in the spleen or lymph nodes
swelling in the joints
