Can a person with undetectable viral load test HIV negative on rapid HIV test?
The viral load test and HIV test look for different things.
The HIV test is an antibody test that shows whether your immune system has ever reacted to HIV infection. Usually this immune response lasts for a lifetime. It is not related to viral load.
However, sometimes people who start meds VERY soon after the caught HIV (ie within days or weeks) had been reported to later test HIV negative. This doesnt mean they are cured though. If the meds are stopped, viral load is likely to rebound very quickly – and they will also test positive again on the rapid antibody test.
