CD4 Count

CD4+ T cells are a type of white blood cell vital for immune function. They help fight off infections by signaling other immune cells to respond.

The CD4 Count test helps assess the strength of the immune system by quantifying the number of CD+4 T lymphocytes in the blood. A doctor may suggest the CD4 Count test if an individual has been diagnosed with HIV infection or is suspected of having HIV Infection. This test helps in the diagnosis, staging, and monitoring of HIV or acquired immunodeficiency syndrome (AIDS). For patients with HIV, the CD4 Count test helps determine the stage of infection, when to initiate antiretroviral therapy (ART), and how well the treatment is working. This test also helps monitor immune system status in other immunocompromised conditions, and symptoms suggestive of an opportunistic infection, or other complications related to HIV.

Additionally, the CD4 Count test can be done in other clinical scenarios involving immune suppression, such as congenital or acquired immunodeficiencies (e.g. SCID, Digeorge syndrome), patients undergoing chemotherapy, immunosuppressive therapy or organ transplantation, and those with autoimmune disease or protein energy malnutrition.

No special preparation is required for the CD4 Count test. However, provide a brief clinical history at the time of sample collection. Inform a doctor about all the medications (e.g., immunosuppressants, steroids, etc.), supplements, and underlying illnesses, as all these factors may affect the test results.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and reference standards used. High levels of CD4 cell counts indicate a healthy immune system, while low levels may suggest a weak immune system and a high risk of opportunistic infections. Do not self-medicate, and always consult a doctor to understand the test results correctly.
