  • CD4 (T-CELL) TESTSWHAT ARE CD4 CELLS?WHY ARE CD4 CELLS IMPORTANT IN HIV?WHAT FACTORS INFLUENCE A CD4 CELL COUNT?HOW ARE THE TEST RESULTS REPORTED?WHAT DO THE NUMBERS MEAN?WHAT ARE CD4 CELLS?CD4 cells are a type of lymphocyte (white blood cell). They are an important part of the immune system. CD4 cells are sometimes called T-cells. There are two main types of T-cells. T-4 cells, also called CD4+, are \"helper\" cells. They lead the attack against infections. T-8 cells, (CD8+), are \"suppressor\" cells that end the immune response. CD8+ cells can also be ?killer? cells that kill cancer cells and cells infected with a virus. Researchers can tell these cells apart by specific proteins on the cell surface. A T-4 cell is a T-cell with CD4 molecules on its surface. This type of T-cell is also called ?CD4 positive,? or CD4+. WHY ARE CD4 CELLS IMPORTANT IN HIV?When HIV infects humans, the cells it infects most often are CD4 cells. The virus becomes part of the cells, and when they multiply to fight an infection, they also make more copies of HIV.When someone is infected with HIV for a long time, the number of CD4 cells they have (their CD4 cell count) goes down. This is a sign that the immune system is being weakened. The lower the CD4 cell count, the more likely the person will get sick.There are millions of different families of CD4 cells. Each family is designed to fight a specific type of germ. When HIV reduces the number of CD4 cells, some of these families can be totally wiped out. You can lose the ability to fight off the particular germs those families were designed for. If this happens, you might develop an opportunistic infection (See Fact Sheet 500). WHAT FACTORS INFLUENCE A CD4 CELL COUNT?The CD4 cell value bounces around a lot. Time of day, fatigue, and stress can affect the test results. It's best to have blood drawn at the same time of day for each CD4 cell test, and to use the same laboratory.Infections can have a large impact on CD4 cell counts. When your body fights an infection, the number of white blood cells (lymphocytes) goes up. CD4 and CD8 counts go up, too. Vaccinations can cause the same effects. Don't check your CD4 cells until a couple of weeks after you recover from an infection or get a vaccination.HOW ARE THE TEST RESULTS REPORTED?CD4 cell tests are normally reported as the number of cells in a cubic millimeter of blood, or mm3. There is some disagreement about the normal range for CD4 cell counts, but normal CD4 counts are between 500 and 1600, and CD8 counts are between 375 and 1100. CD4 counts drop dramatically in people with HIV, in some cases down to zero.The ratio of CD4 cells to CD8 cells is often reported. This is calculated by dividing the CD4 value by the CD8 value. In healthy people, this ratio is between 0.9 and 1.9, meaning that there are about 1 to 2 CD4 cells for every CD8 cell. In people with HIV infection, this ratio drops dramatically, meaning that there are many times more CD8 cells than CD4 cells.Because the CD4 counts are so variable, some health care providers prefer to look at the CD4 percentages. These percentages refer to total lymphocytes. If your test reports CD4% = 34%, that means that 34% of your lymphocytes were CD4 cells. This percentage is more stable than the number of CD4 cells. The normal range is between 20% and 40%. A CD4 percentage below 14% indicates serious immune damage. It is a sign of AIDS in people with HIV infection. A recent study showed that the CD4% is a predictor of HIV disease progression. WHAT DO THE NUMBERS MEAN?The meaning of CD8 cell counts is not clear, but it is being studied.The CD4 cell count is a key measure of the health of the immune system. The lower the count, the greater damage HIV has done. Anyone who has less than 200 CD4 cells, or a CD4 percentage less than 14%, is considered to have AIDS according to the US Centers for Disease Control.CD4 counts are used together with the viral load to estimate how long someone will stay healthy. See Fact Sheet 125 for more information on the viral load test.CD4 counts are also used to indicate when to start certain types of drug therapy:When to start antiretroviral therapy (ART):When the CD4 count goes below 350, most health care providers begin ART (see Fact Sheet 403). Also, some health care providers use the CD4% going below 15% as a sign to start aggressive ART, even if the CD4 count is high. More conservative health care providers might wait until the CD4 count drops to near 200 before starting treatment. A recent study found that starting treatment with a CD4% below 5% was strongly linked to a poor outcome.When to start drugs to prevent opportunistic infections:Most health care providers prescribe drugs to prevent opportunistic infections at the following CD4 levels:Less than 200: pneumocystis pneumonia (PCP)Less than 100: toxoplasmosis and cryptococcosisLess than 75: mycobacterium avium complex (MAC). Because they are such an important indicator of the strength of the immune system, official treatment guideline in the US suggest that CD4 counts be monitored every 3 to 4 months. See Fact Sheet 404 for more information on the treatment guidelines.
