Description:
The CD4-T Cell Count Test measures the number of CD4-T lymphocytes (a type of white blood cell) in a blood sample. These cells are essential for a healthy immune system as they help fight infections. Here's an overview:
Purpose:
1. HIV Monitoring: CD4 counts are used to monitor the immune status of people living with HIV. A declining count indicates immune suppression and progression of the disease.
2. Assessing Treatment: The test evaluates the effectiveness of antiretroviral therapy (ART) in HIV patients.
3. General Immune Health: It can also assess immune function in non-HIV conditions, such as autoimmune disorders or after chemotherapy.
Normal Range:
• A healthy CD4 count ranges between 500 to 1,500 cells/mm³ of blood.
• A count below 200 cells/mm³ is a marker for severe immune suppression and an increased risk of opportunistic infections.
Procedure:
A blood sample is drawn and analyzed in a laboratory to determine the CD4 count.
Significance:
Regular CD4 testing helps guide treatment decisions, such as when to start prophylactic medications to prevent infections and adjust ART regimens. It is a vital tool in managing and improving the quality of life for individuals with compromised immune systems.
