Hiv (Definition)

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

First unprotected sex on 9th June. Antibody test on 14th June & 14 July. Aptima HIV-1 RNA, Qualitative, TMA on 20th may. All negative. Should I worry?

First unprotected sex on 9th June. Antibody test on 14th June & 14 July. Aptima HIV-1 RNA, Qualitative, TMA on 20th may. All negative. Should I worry?

Repeat in 6 months: Just to be sure repeat the HIV nucleic acid test 6 months after the June episode. I trust you got tested for other STDs as well.
Wish you good health. Read more

Will hiv-1 RNA after 28 days also detect year old encounters.

HIV testing: Yes a negative test means you are negative and do not have hiv. All previous encounters would be cleared. Read more

Is it true that HIV 1 RNA test at 10 days post possible exposure considered confirmative?

Is it true that HIV 1 RNA test at 10 days post possible exposure considered confirmative?

If positive: If positive, the test is confirmative of HIV infection. Negative result at 10 days post exposure does not rule out HIV infection. Read more

Protected sex with csw, unprotected recptive oral. What is the risk of hiv? I tested neg for syph, chla, & ghon. 28 day hiv-1 RNA test neg.

Protected sex with csw, unprotected recptive oral. What is the risk of hiv? I tested neg for syph, chla, & ghon. 28 day hiv-1 RNA test neg.

No HIV risk: There is no HIV risk from saliva to the penis in oral sex. As the receptive partner you will not get hiv. But, you tested and, as expected, the test was negative. You did everything right. Go live your life. 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

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

HIV negative: If your fourth generation test and RNA tests are both negative at 5 months after an HIV exposure, as long as you haven't had any other exposures in the meantime, then yes you would be considered HIV-negative. Read more

I had 7 hiv duo test at 3rd 4th 6th 8th 12.7th 13.3 th 15th 1) antiobdy 9.5 week 1) hiv 1 rna pcr qualitative at 14.5 week All -Non reactive hiv?

Stop testing!: You have been seriously overtested for HIV. The duo test is always positive within 4 weeks of infection. Every test after that was superfluous and a waste of money. It is past time to move on without further worry about it. 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

Hi, had HIV-1 rna pcr @ 5 weeks & 5 months. And HIV ag/ab DUO at 1, 2, 4 & 6 months. Do I need further testing for HIV or do I need HIV-2 pcr or did the DUO rule it out?, or is it too rare to worry about in MI? I leave in Novi, MI. Thank you

HIV: Assuming what you have described is accurate, you do not have HIV infection and do not need further testing unless there have been subsequent exposures. Good luck and be careful out there. Read more

Is hiv 1 rna pcr qualitative and elisa 3rd gen test reliable after 4.5 months of exposure. Both came not detected?

100% reliable: Either of these tests, by itself, proves 100% you don't have HIV. There is no chance you are infected. Stop testing and stop worrying about HIV, no matter what exposure or symptoms you may have. Read more

Given that HIV 1 RNA PCR test result undetectable 25 days after possible exposure, when and which HIV test to take next?

HIV: If you are negative by HIV RNA PCR at 25 days after exposure the chances of you becoming HIV positive are next to nil. If you really want to test yourself a combination test which includes p24 antigen and HIV antibody can be done at 3 months. Think you are going to be fine. Read more

Hiv-1 RNA PCR result is undetected, worried about hiv-2 in Germany. Dr didn't see necessary to take antibody test even at w12.What should I do?

Hiv-1 RNA PCR result is undetected, worried about hiv-2 in Germany. Dr didn't 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
