It is very sensisitive for detecting the presence of certain bacteria and is also used in doing other ...Read more
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

What is the level of sensitivity of the HIV-1 RNA PCR test by Aptima? Is it accurate at 2 to 3 weeks post exposure?
Yes: Read the CDC updated recommendations on HIV testing. The rationale for this test being available is that HIV RNA is detectable in plasma before antibodies. A safe approach is to be tested after the eclipse period after potential exposure when no RNA nor antibodies to HIV can be detected. The RNA test is effective around 10 days after infection but seroconversion to antibodies may take 3 months. ...Read more
Can hiv-1 RNA PCR detect hiv-2 at some point or can not detect?If you consider Poland, can you exclude HIV possibility with hiv-1 RNA PCR test only?
HIV Online: We are very experienced here with what we call HIV panic. There is little we will say that will ease your panic. HIV 1 in the disease you are at risk for in Poland in general. Your HIV RNA test is negative. If you cannot get past this worry then go get an HIV 1/2 antibody test with the P24 antigen test as well. Then test every twelve weeks. And if you are at risk get on Truvada (emtricitabine and tenofovir) to prevent. ...Read more

Hiv-1 RNA PCR result is undetected,worried about hiv-2 in Germany. Dr didnt see necessary to take antibody test even at w12.What should I do?
Wait: You must wait. Or get an HIV 1/2 antibody test but know you will have to repeat it in the future. At twelve weeks it cannot be 100% accurate. in the future if you have a high risk exposure there is a treatment to prevent infection if started within 72 hours. If you have repeated high risk exposures there is a treatment to take before exposure to prevent infection. ...Read more

Does cobas taqman v 2 for HIV 1 RNA check for all groups N, O, P, M and all subtypes of M. If not, what it doesn't check. Please answer, Thanks?
A technical question: I am looking at the Roche website regarding this test and it says this test, "Quantifies the clinically significant HIV-1 groups and subtypes with full subtype coverage and quantifications of HIV-1 groups O and M" It is a confirmatory, not screening test. I believe you would need to contact the company if you need more specific information than this. Good wishes:) ...Read more
Is a HIV ag/ab eia and a hiv-1 Rna test conclusive at 5 months ? I also had a 4th gen test 3 months ago both negative. Blood was cold if that matters
I understand the p24 and hiv-1 rna test are specifically designed for hiv-1, not hiv-2. Is there any cross-reactivity with the p24 and rna for hiv-2?
HIV: Do not know which test kit was being used, but most today cover both Types 1 & 2. Check with the lab that ran the test. Good luck. ...Read more

Thirdly by pcr (polymerase chain reaction) which ...Read more
