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
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?
Hiv DNA PCR dectected on 4/08/13 and antibody negative. Still now 6/3/13 8 weeks later still show HIV anitbody negative. What are your thoughts? Is the PCR a false positive?
Not necessarily: Is it really the dna or the RNA pcr? The dna qualitative pcr is the most sensitive test and may become positive months before antibody is detected. The quantitative RNA pcr that is used for monitoring also becomes positive early. Antibodies may not develop until 3 months from the infection. So, they may still develop. If you have not seen a HIV physician and are not on art, see one asap. ...Read more
I had unprotected oral sex 8 week ago I had 2 HIV DNA PCR test at 18 days and 46 days negative and 2 fourth generation test at 28 days and 42 days neg?
HIV: The overwhelming probability is that you did not get HIV infection. You do not say whether the oral sex was done to you (in which case you were not in any significant risk), or whether you did it to a woman (not a risk). If you did to another man and semen hit the back of your throat that is a good way to become infected so in the future make sure he has a condom on. You are going to be fine. ...Read more
Hi doctors, 20+ hiv 4th gen test (upto 14 months), 1 rna pcr (@20 weeks), 2 dna pcr (@11 & 18 week). All neg. Am I 100% free of Hiv or need more tests?
You can quit testing.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...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?
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
I had sex. Used condom. I am in a very high stress. Its 7 week since exoosure. I want to get accurate result, RNA pcr, DNA PCR be conducted cost no issue?
Happy New year. How accurate is a DNA PCR HIV Test with Negative results Past 32 weeks of unprotected sex and 2weeks past protected sex with a csw?
Happy for you: You didn't get HIV from your first adventure. Protected sex when you're a man is unlikely to transmit HIV. How about playing really safe from now on -- not so much out of fear, but out of respect for that one special person who may be in your future? You can get plenty else from messing around -- including unwanted complications. It's a rare, wise guy who works hard to stay clean. Best wishes. ...Read more
I had a recent high risk exposure. At 5 weeks I did the HIV antibody test and at 7 weeks the PCR DNA test both came back negative is this conclusive?
According to the guidelines, following exposure, one may not convert to hiv+ for up to 6 months. It's a good sign that both these test have been negative so far and retesting every 3 months for antibody would be relatively inexpensive. Take precautions when engaging in any high risk activity.

Unprotected oral sex: I am assuming you are concerned about your HIV risk. Based on the information you provided I think your risk is low with the three negative tests. HOWEVER - your behavior is risky. Saliva can contain the HIV virus and while you may not have any cuts or sores - your partner could easily scratch or bite you. Be careful!! ...Read more
HIV testing: Yes. Of course. It is accurate from 14 days post exposure. ...Read more
Does an HIV dna/pcr test become more or less sensitive and conclusive after the 1 month mark? After 3 or 5 months?
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
Highly probable: This is almost invariably the case.Get a more detailed answer ›
Got negative result at 15 th day of my post exposure. Now can I trust on the HIV proviral DNA PCR result?
May be too early: Hiv nucleic acid test may not turn positive in two weeks. A negative result is good but you need to be retested in three too six months to be sure. Did you get post-exposure prophylaxis? Please talk to your doctor about prophylaxis, informing your sex partners and your follow-up care. ...Read more
Hiv has many types and subtypes. So can an HIV DNA PCR test after 21 days of possible exposure rule out HIV completely?
HIV testing: Certainly possible exposure to HIV is worrisome. Rest assured however that HIV testing is extremely good. The standard PCR test is used when a patient might be in the "window period"- that is between the time from infection until an antibody response is registered by the body. Your doc ordered the right test & u can breathe a sigh of relief. Please be careful next time tho-- this & other STDs suck ...Read more
Hi. Just wanted to know how accurate is a HIV DNA PCR test at 6 and 21 days after exposure. Both tests came back as not detected.?
Negative: The overwhelming probability is that you are negative. This is a very accurate test and rapidly becomes positive in infected individuals. The test actually measures rna. This virus is call a retrovirus because in the cell it is converted to dna and then intercalated into the cell genome. ...Read more
