Lymphocytes are a group of white blood cells involved in the operation of the immune system. They include natural killer cells, T cells and B cells. They make up the majority of lymph tissue. They are created in the bone marrow.

A high lymphocyte count is a sign of a viral infection or, less commonly, leukemia. Low lymphocyte counts are almost always due to post-surgery infection, but can also be caused by the HIV virus, which attacks T cells.
