The CD4/CD8 test is a blood test that measures the levels of two types of T-lymphocytes (T-cells) — CD4 and CD8 cells — which are crucial components of the immune system. These cells help the body fight infections:
• CD4 cells (also known as T-helper cells) coordinate the immune response.
• CD8 cells (also known as cytotoxic T cells) kill virus-infected and cancerous cells.
The test typically reports:
• Absolute CD4 count
• Absolute CD8 count
• The CD4/CD8 ratio
This test is most commonly used in monitoring HIV (Human Immunodeficiency Virus) infection.

Description

Why It’s Done:

The CD4/CD8 test is used to:
• Diagnose and monitor HIV/AIDS by assessing immune function.
• Evaluate the progression of HIV and guide treatment decisions.
• Monitor response to antiretroviral therapy (ART) in HIV-positive patients.
• Investigate causes of immune system disorders or immunodeficiency.
• Assess immune recovery following bone marrow or organ transplants.
• Help diagnose certain autoimmune diseases, cancers, or infections that affect T-cell populations.

Preparation:

• No fasting or special preparation is typically needed.
• Inform your doctor about any medications, especially those that may affect immune function (e.g., corticosteroids or immunosuppressants).
• A blood sample will be collected from a vein in your arm
