Lymphocyte Activity Profile

Clinical Use

Use

The Lymphocyte Activity Profile is a test designed to measure the activity and distribution of various subsets of lymphocytes using flow cytometry. It provides diagnostic and prognostic insights into immune function by analyzing markers on lymphocytes, making it particularly relevant in the context of immune disorders, infections, and monitoring the immune response.

Limitations

This test has not been cleared or approved by the FDA, which may have implications for its use in certain clinical scenarios. The stability of specimens is limited to room temperature, and they are not stable if refrigerated or frozen. Hemolysis, contamination, or clotting can be causes for rejection of the specimen. Additionally, testing schedules may vary, and additional time should be allowed for confirmatory or reflex testing.
