How accurate is the hiv-dna by pcr?

Nucleic acid Test : Hiv is a RNA virus. Nucleic acid testing (nat) is done to (1) detect virus for an early diagnosis after potential exposure; (2) donated blood to detect infection, (3) to measure the viral load in someone undergoing treatment for hiv. Nat may be negative up to two weeks or so after acquiring infection. It is the most accurate of the tests for hiv. ...Read more

Polymerase Chain Reaction (Definition)

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

Why is the HIV DNA PCR test not recommended after 4 weeks of exposure? Would it still be a good measure if used past a 3 month time frame?

Why is the HIV DNA PCR test not recommended after 4 weeks of exposure? Would it still be a good measure if used past a 3 month time frame?

HIV RNA PCR: It is completely diagnostic at four weeks. Who told you otherwise? But it must be combined with one of the newer generation antibody tests in case you happen to have a natural ability to suppress the viral replication. ...Read more

Highly unlikley: But hopefully you were also tested for a host of other stds at the same time. The lesson is universal barrier protection. With mono-like illness this could be one of many other diseases, like cmv, toxoplasma, and so on. Only a detailed work-up is likely to clear this up, but then you have to ask yourself if it will make a difference in your long-term health, particularly if you are now better. ...Read more

Too soon: Not reliable at all. I am shocked anyone would even offer you such a test before the test could possibly be valid! the HIV pcr test can be accurate after fourteen days. Most of us wait till day 21 after exposure to erase all doubts. You tested too soon! ...Read more

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?

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
