FAQ
Frequently asked questions
What is a normal CD4 count?
A normal CD4 count is generally considered to be between 500 and 1,600 cells per cubic millimeter of blood. However, this can vary, and your healthcare provider will interpret your results in the context of your overall health.
How does HIV affect CD4 counts?
HIV primarily attacks and destroys CD4 cells. As the infection progresses without treatment, the number of CD4 cells decreases, weakening the immune system and making the body more vulnerable to infections.
Can this test be used for other conditions?
While commonly used for HIV monitoring, a CD4 count can also provide information about general immune system function and may be ordered in cases of suspected immunodeficiency or other immune-related disorders.
How often should this test be performed?
The frequency of CD4 testing depends on your individual health status, HIV diagnosis, and treatment plan. Your healthcare provider will determine the appropriate testing schedule for you.
