I am totally confused. If you are HIV-negative, why are having all these viral load tests done? There is such a thing as a false positive viral load: low viral loads (like 1000) can sometimes occur in someone without HIV infection. It would be... Read more »

Not knowing any of the treatment history it's hard to comment. However, a CD4 cell change from 18 to 8 is not significant. Cells are measured in # cells/mm3, or in percentage of CD4 cells. Likewise at such high viral load levels, a change from... Read more »

"The test can be used for diagnosis, because it can detect a viral load a few days after HIV infection. This is better than the standard HIV (antibody) test, which can be "negative" for 2 to 6 months after HIV infection." If the antibody test can be... Read more »
