Term Description

Absolute CD4 T-cell counts are required to monitor immune status of HIV patients both for prognosis and to decide about initiating treatment. Measuring the absolute CD4 T-cells requires a measure of the absolute lymphocyte count. This can be obtained from the cell counters that produce a CBC with auto diff. It can also be obtained directly from the flow cytometer by using special beads and counting cells with CD45 markers- which identify lymphocytes. CDC recommended the single platform approach (Guidelines for Performing Single-Platform Absolute CD4+ T-Cell Determinations with CD45 Gating for Persons Infected with Human Immunodeficiency Virus MMR. January 31, 2003 / 52(RR02);1-13)
