A normal lymphocyte range is between 1,000 and 4,800 cells in 1 microliter (µL). of blood. A diagnosis of chronic lymphocytic leukemia requires a lymphocyte level of greater than or equal to 5,000 B cells per µL for a minimum of 3 months. This is called monoclonal lymphocytosis. Monoclonal means that the cancer cells all came from one original cell. A high lymphocyte count can point to infection (bacterial, viral, or other type), cancer of the blood or lymphatic system. Check with a hematology oncologist for treatment. Thank you.

Repeat lab work and keep seeing your doctor

You should hopefully be fine- I recommend following up with your Primary Care Doctor as well.

An elevated lymphocyte count in adults may mean that a condition called chronic lymphocytic leukemia is present. Ask your doctor about a flow cytometry study to screen for CLL.
