About CD4 Count Test | Lymphocyte Count for HIV & Immunodeficiency in Normal
CD4 cells are a type of T lymphocyte that coordinate the immune response. Measuring them helps clinicians assess how well the immune system is functioning and whether it is being affected by disease or treatment.
The test uses a blood sample and flow cytometry to identify and count cells carrying specific surface markers. The panel reports CD3 (total T cells), CD4 (helper T cells), CD8 (cytotoxic T cells), the CD4/CD8 ratio, and the natural killer and B cell markers CD16/56 and CD19.
Because HIV targets CD4 cells, serial CD4 counts are a standard part of HIV monitoring. A falling count can indicate disease progression, while a stable or rising count may suggest that immune function is being preserved or restored.
Results are interpreted alongside other laboratory values and clinical findings, not in isolation. Reference ranges vary by laboratory, so trends over time are often more informative than any single measurement.
