The CD4 Lymphocyte Count test at Pamel Laboratories measures the number of CD4 T-cells (a type of white blood cell) in your blood. CD4 cells play a critical role in your immune system by helping your body fight infections. This test is especially important for individuals living with HIV/AIDS, as it helps assess the stage of infection, determine when to start or adjust antiretroviral therapy (ART), and monitor immune system recovery.
A low CD4 count indicates a weakened immune system, increasing the risk of opportunistic infections.
Purpose of the Test:
-
Monitor HIV progression and treatment response
-
Assess immune system strength
-
Guide decisions about starting or modifying antiretroviral therapy (ART)
-
Diagnose and monitor immune suppression or autoimmune diseases
-
Predict risk for opportunistic infections (e.g., tuberculosis, pneumonia)
Normal Range:
-
Healthy adults: 500 – 1,500 cells/mm³
-
Below 500 cells/mm³: Weakened immune function
-
Below 200 cells/mm³: Risk of severe opportunistic infections (AIDS-defining)
Sample Type: Venous blood
Turnaround Time: 24–48 hours
Test Method: Flow Cytometry (gold standard for CD4 testing)
