Test Normal Range:
CD4 T-Cell Count: Normal range varies by age and can be between 500 and 1600 cells/mm³ (cubic millimeters).
CD8 T-Cell Count: Normal range can be between 200 and 1000 cells/mm³.
What is the Test?
The CD4 and CD8 Cell Count test measures the number of CD4 and CD8 T-lymphocytes, which are important immune system cells. CD4 cells are helper cells that coordinate the immune response, while CD8 cells are cytotoxic cells that destroy infected or abnormal cells.
Test Procedure:
Blood Drawn: A medical practitioner will take a sample of your blood from a vein in your arm. Laboratory Analysis: The blood sample is sent to a laboratory for analysis to determine the CD4 and CD8 cell counts.
When to Take the Test:
Individuals with HIV/AIDS to monitor the progression of the disease and immune system health.
Those with autoimmune disorders, cancer, or other immune-related conditions.
People undergoing organ transplantation or immune-suppressive treatments.
Who Should Take This Test:
Individuals with HIV/AIDS to monitor the health of their immune system.
People with autoimmune disorders to assess immune system activity.
Those undergoing treatments that may affect the immune system.
Precautions for Exceptional Cases (Pregnancy etc.):
Pregnant individuals should inform their healthcare provider, as pregnancy can affect immune cell counts.
