Lymphocytopenia is the condition of having an abnormally low level of lymphocytes in the blood. Lymphocytes are a white blood cell with important functions in the immune system. It is also called lymphopenia.[1] The opposite is lymphocytosis, which refers to an excessive level of lymphocytes.

Lymphocytopenia may be present as part of a pancytopenia, when the total numbers of all types of blood cells are reduced.
