CD4 (T-Cell) Tests

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 CD4 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...

CD4 and CD4/CD8 ratio

Dear Cal, I have been recently diagnosed HIV+ (June 02) and have some questions regarding both the CD4/CD8 ratio and CD4 which do not seem to be spoken about as much as the CD4 absolute.My first question is what exactly are CD8 cells? What happens...

Thanks Jim - glad this helps.So - about these cell counts. We simplify the immune system to make it easier to count and report things. And one important simplification is this one - we can distinguish two major types of important cells in the... Read more »

CD4 - CD4:CD8 - CD4 keeps going down and doc says don't worry. It will not do any good.

Hello,You should be evaluated and treated by a clinical immunologist. There are other immunological conditions that can cause lymphopenia other than HIV-1 or HIV-2. It appears that HIV has more than been ruled out by your 32 negative tests!... Read more »

CD4 percentage & CD4/CD8 ratio

There seems a lot of information about the average annual decline in CD4 cells (50-75 or 3% per year)and thus one might be able to estimate how long it will take for one's own absolute CD4 count to fall below 500 (or the critical 350 mark), BUT...

Hi,
dropping by this bulletin-board, I see there is a lot of use and abuse of t-cell subsets among worried wells. To put things in perspective - cd4/cd8-ratios were used as a surrogate marker of HIV-infection among blood donors at a US hospital... Read more »
