Just few days. Depends how fast the genetic lab receives the specimen, HIV virus dna analysed and identfied by pollymer chain reaction, or PCR making copies of sequence and identifies.
Need more info. To give an answer to your question more information is needed. Did you recently start medications to treat hiv, then the answer is after about 1-2 months. Did you recently engage in a high risk activity, such as unprotected anal intercourse? In that case, I would advise first and foremost to use protection in the future and to be tested as soon as possible. Hiv may show up as soon as 7-10 days.
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?
You mean RNA. These are RNA-based retroviruses. The PCR assays for the two strains are distinct.
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,
Does DNA PCR test for HIV 1&2 lose sensitivity over time? How accurate can a negative result for DNA PCR be on checking at 89 days post exposure?
No sensitivity loss. These tests do not lose sensitivty over time. A negative result at almost 3 months is almost 100% conclusive. However, to reach 100% certainty, you also need an antibody test, if not already done.
Got tested after 45 days, my results HIV-1&2 Antibodies-Non reactive. HIV-P24 Antigen-Non reactive. HIV DNA PCR-Not detected. Am I clear? Please advice.
Likely. It would be prudent to retest at six months after exposure. If the HIV nucleic acid test is negative then, you would be free.
Very accurate. Very accurate.
Is hiv-1-pcr quantitative and HIV RNA PCR quantitative same tests? Can DNA PCR test be quantitative?
HIV testing. Yes. Viral testing can be qualitative or quantitative. Most HIV RNA testing is quantitative.
How many types of HIV are there? I did HIV DNA PCR for HIV 1 only I'm afraid If I'm infected by other types.
HIV risks. There are two major strains of HIV in the world - HIV-1 and HIV-2. Almost all infections are HIV-1 unless you live in W. Africa where there is some HIV-2. If your test was negative then that is great. You should still be careful though because HIV infection requires life long medication to manage it. Probably best to get follow up with your doc. There are lots of ways to have safe sex-b careful.
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?
Yes. You have had the required tests and if HIV RNA test was negative at more than 3 months after exposure, you are safe.
