Total Lymphocyte

A high total means more lymphocytes were counted than the reference range shown. A recent viral infection can cause a temporary rise. Compare previous blood counts and the individual cell results to see which populations contribute to the increase. Review a persistent elevation with your clinician; the total alone does not identify its cause.

A low total means fewer lymphocytes were counted than the reference range shown. Reductions can occur with illness or some medications. The individual T-, B-, and NK-cell results help clarify which populations are affected. Review a persistent reduction with your clinician, especially if infections are recurrent.

This result counts circulating lymphocytes per microliter of blood, including T cells, B cells, and natural killer cells. A total within range can still contain an individual subset outside range. Read it with the individual cell counts to understand how the total is distributed.
