Cell Surface Immunophenotyping
(AIDS T-Lymphocyte Cell Markers)
- CD4 Markers
- T4 Count
- T-Helper Cells
As blood cells are formed and mature, there are different types and numbers of markers that can be measured and the values used to diagnose and differentiate between different types of leukemia, and to determine which treatment is most appropriate. Markers are also examined in people who have decreased immune system diseases such as AIDS/HIV. Low levels of CD4 T-lymphocytes are used to diagnose AIDS, as a predictor of possible complications and infections, and to determine when to begin anti-viral medication therapy. This test is also used to determine how well anti-rejection medication is working after an organ transplant.
