Hiv 2 Proviral Dna Qual Pcr
I had unprotected oral sex on me I saw no blood I have no sores I am circumsized I have tooken a HIV dna pcr test at 18 days and a 46 also a 4 week and 6 week duo test and a 8 week rapid test am I ok?
You're OK: Oral sex is safe sex for HIV, with no proved transmissions by fellatio from mouth to penis, only rare ones penis to oral. You didn't need testing on account of this event and for sure not the multiple expensive ones you had. But the results from that combination of tests are conclusive. For sure you didn't catch HIV during that exposure and no further testing is needed. Best wishes and stay safe! ...Read more
Polymerase chain reaction is a method of finding a specific piece of dna and copying it over and over again until there is enough to study. The technique allows a scientist to detect very small amounts of dna in a swab sample then reproduce enough of it to study it. It is very sensisitive for detecting the presence of certain bacteria and is also used in doing other ...Read more
I am wondering about HIV results. I have tested at 5 months post exposure with dna/pcr, antibody, western blot test (negative). Is this conclusive?
Is my 8 wks 2 day PCR RNA + 4th Gen test negative conclusive for HIV infection after vaginal exp? Or do i need to test after 12 wks or it has to be after 13 wks? Pls answer, Thanks for any response
Relax, Mike: I understand that you're a man worried about HIV after an unprotected episode of intercourse with a woman. The nucleic acid tests are almost always positive by this time -- we can't even estimate the frequency of their turning positive only at 12 weeks because history isn't always accurate. Retest only if you or someone close to you is obsessed over it. Love wisely and well from now on. Cheers. ...Read more
Do HIV 1 and HIV 2 DNA differ form each other?and is there seperated DNA PCR tests for each or one is enough to catch both?
I did HIV DNA PCR and results came negative after 21 days but only for HIV 1 my question is if I had HIV 2 would this test detect it as well?
Yes: This test is specific for both Types 1 & 2, ...Read more
Hi, had sex & HIV-1 rna pcr @ 5 wks & 5 mths & HIV ag/ab DUO @ 6 mths. do I need HIV-2 dna pcr? I'm in metro detroit, hiv-2 should be rare. Am I safe?
Does NAT test accurate for detecting HIV-2?
is there a PCR specific for HIV2 or Hiv PCR detect both as I was told by my HP there is none specific
HIV is a virus, thus: no test is perfectly accurate. Study: http://www.questdiagnostics.com/testcenter/testguide.action%3Fdc%3DTG_HIV_Management & https://www.google.com/#q=HIV%20testing for reasonable information on current clinically available technology. You are on the right track to study the issues yourself. You have the most vested interest & are your own primary medical decision maker (physician if you will). ...Read more
A friend had hiv test at 6 months last exposure negative,now he had a pos for hiv-2 at 7 months.He also did a pcr at 4 months.can it be false positive?
Probably false pos: HIV-2 is very rare outslide the area of west Africa where it originated (Cameroon), although I don't know about Albania for sure. The PCR should have picked up HIV-2 as well as HIV-1. So your freind's HIV-2 test probably is false positive. He should see an infectious diseases or HIV expert to sort it out. ...Read more
Hi I had HIV-1 rna pcr @ 5 wks & 5 mths & HIV ag/ab DUO at 1, 2, 4 & 6 mths. Do I need further testing for HIV-2 or am I safe? I'm in metro Detroit.
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
