Special Info

Samples received between 24 and 48 hours of draw time will be performed and reported along with a lymphocyte viability. Samples received between 48 and 72 hours old will performed and reported along with a lymphocyte viability; however, NK results may not be accurate. Recommend obtaining a fresh sample if clinically indicated. Samples that are less than 75% viable will be rejected and a redraw will be requested. Samples received in testing lab beyond 72 hours cannot be performed. Refrigerated samples may give abberant results and will be rejected.

Clinical Info

This is a single platform, 6-color Flow Cytometry assay used to enumerate CD3+ T cells; CD3+CD4+ T cells; CD3+CD8+ T cells; CD19+ B cells; CD3-CD16/56+ NK cells; and CD4/CD8 Ratio in peripheral blood. These lymphocyte subset percentages and counts are used in the monitoring of Immunodeficiency, HIV infection, and other immunologic disorders.
