Why Choose the CD?4 Count Test?

The CD?4 (helper T-cell) count is a key indicator of your immune system’s strength. It’s most important for people living with HIV (PLHIV), helping track immune health and gauge the effectiveness of antiretroviral therapy. While a CD?4 test isn’t used to diagnose HIV, a healthy count—typically above 400 cells/µL—is a good sign of immune resilience

The test also measures CD?3 and CD?8 cells:

CD?3: Essential to overall T?cell function.

CD?8: Cytotoxic T cells involved in defeating infections and abnormal cells. Elevated CD?8 is common during HIV infection

? Who Should Take This Test

PLHIV seeking regular immune system monitoring
Individuals undergoing immunosuppressive treatments such as for organ transplants or autoimmune disorders
Patients needing assessment of T?cell reconstitution (e.g., post-transplant) or primary immunodeficiencies
