What does a CD4 count of 250 mean?
HIV CD4 count range: 250–500 cells per cubic millimeter (250–500 cells/mm³). It means you have a weakened immune system and may be infected with HIV. AIDS CD4 count range: 200 or fewer cells per cubic millimeter (<200 cells/mm³). It indicates AIDS and a high risk of life-threatening opportunistic infections.
What should I do if my CD4 count is low?
Persons with very low CD4 counts may need to take drugs to prevent specific opportunistic infections in addition to taking their ART. Once the CD4 count increases in response to ART, it may be possible to stop taking these OI medications.
How often should I get a CD4 count?
Your health care provider may order a CD4 count when you are first diagnosed with HIV. You will probably be tested again every few months to see if your counts have changed since your first test. If you are being treated for HIV, your health care provider may order regular CD4 counts to see how well your medicines are working.

Results
Prognosis
- Keeping your CD4 count up with an effective antiviral treatment can hold off symptoms and complications of HIV and help you live longer. In fact, studies have found that patients who adhere to regular treatments can achieve a life span similar to persons who have not been infect…
Prevention
- Persons with very low CD4 counts may need to take drugs to prevent specific opportunistic infections in addition to taking their ART. Once the CD4 count increases in response to ART, it may be possible to stop taking these OI medications.
Causes
- HIV damages your immune system because it targets CD4 cells. The virus grabs on to the surface of a cell, gets inside, and becomes a part of it. As an infected CD4 cell multiplies so it can do its job, it also makes more copies of HIV. HIV can destroy entire \"families\" of CD4 cells, and then the germs these cells fight have easy access to your body. The resulting illnesses are called opp…
Pathophysiology
- Those new bits of virus find and take over more CD4 cells, and the cycle continues. This leads to fewer and fewer HIV-free, working CD4 cells.
Clinical significance
- A normal CD4 count is from 500 to 1,400 cells per cubic millimeter of blood. CD4 counts decrease over time in persons who are not receiving antiretroviral therapy. At levels below 200 cells per cubic millimeter, patients become susceptible to a wide variety of opportunistic infections, many of which can be fatal.
