Early Hiv Detection Test
Hi. How accurate/conclusive is a negative result of HIV RNA (early detection test) taken 4 weeks post exposure? My exposure was pretty low risk as told to me by my doctors. I will obviously be taking other follow up tests as time goes by. Thank you.
Almost 100%: Your "obviously" comment is based on a misconception. RNA testing alone is nearly 100% accurate at 4 weeks. If you also have (or had) a negative antibody test, the results are (or will be) conclusive. The duo test (antibody/antigen) or RNA plus an antibody test are 100% conlcusve at 4 weeks. Going beyond 4 weeks is needed only for stand-alone antibody tests -- and even then, 6-8 weeks is enough. ...Read moreSee 1 more doctor answer

What's the initial management of a patient that has just contracted HIV within the past 3-5 days? What's the prognosis of such "early" detection?
Prognosis good: Some semantics: contracting hiv, means that one has been exposed to the virus, generally through blood exchange, sexual activity with HIV infected person, IV drug use...The test for HIV does not become + for weeks after exposure. Perhaps you mean that a DX of aids was made a few days ago. Either way, early detection makes it very treatable and today likely curable. Infectious disease doc is best. ...Read more
Hi..Please tell how much reliable is rapid detection at home HIV test kit?And please tell me how it is done.Is it done in morning or any time?
HIV Testing: It is very accurate as long as you are three to six months past the exposure. If you are not this far past the exposure the test should be avoided. If you have real risk of HIV there is a better test that can be definite at 21 days post exposure. This is the HIV RNA viral test. The time of day one does this kind of test does not matter in any way. ...Read more
Very accurate: The elisa assay is one of the longest standing tests for antibodies to hiv. Positive results must be confirmed using western blot or other tests. If negative at 3 wks you should be retested at 3 and 6 months to be absolutely certain, but those latter tests are rarely positive if the 3 wk test was negative. Be safe. Have only protected sex until both partners assuredly negative, and monogamous. ...Read more
Why HIV antibody test using blood for detection not semen since someone may have undetectable viral load in blood but detectable in semen ?
Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more
