Hiv 1 Dna Qualitative 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?
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. ...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?
Is hiv-1-pcr quantitative and HIV RNA PCR quantitative same tests?can DNA PCR test be 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 ...Read more

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?
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.
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?
(-)4th gen hiv 1.5,188.8.131.52.5.5 mnth, DNA PCR 10,12 wk, RNA PCR 18 wk, vdrl,hsv,hcv,chlmydia 11,16 wk. R these 100% conclusive after risky exposure?
Stop testing!: You have been seriously overtested, especially for HIV. The 4th gen HIV tests are conclusive any time 4 weeks or more after exposure. All HIV tests after the one at 1.5 months were superfluous and a waste of money and time. The other tests also are conclusive and also didn't need to be done a second time. No matter how high the risk might have been, you can move on without worry. ...Read more

52 days post exposure.What test to take HIV 1 RNA PCR qualitative or quantitative. And does this test detect both HIV 1 abd 2 type?
Inother words would RNA PCR for HIV 1 n cmia duo detect subtype e and other rare subtypes also at 8 months post exposure in thailand ...Many smptms?
Can verify: You'll need to place a call to the lab to be sure they are testing for the rare subtypes, and you have every right to do this. However, if you have "many symptoms" and your only risky exposure was eight months ago, then your symptoms are not due to hiv, as it would be latent at this stage. I suspect you've got a bad case of the "nerves" -- i've had it too, and learned from it. Stay well. ...Read more
Would RNA PCR for HIV 1 n cmia duo detect subtype e n other rare subtypes also at 8 months post xposr n thailnd ..Many smptms?Negative result coclusive?
Yes, but...: The latest pcr tests for HIV should be able to detect the rarer subtypes, but in life, no test is perfect. Life is about chances (probabilities, likelihoods), so if it has been 8 months since a known high risk exposure to HIV and one's primary doctor (or infectious diseases doctor) has done adequate testing, then negative results mean one did not catch HIV that time. Keep in touch with the doctor. ...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
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
