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

Relax, Mike: I understand that you're a man worried about HIV after an unprotected episode of intercourse with a woman. The nucleic acid tests are almost always positive by this time -- we can't even estimate the frequency of their turning positive only at 12 weeks because history isn't always accurate. Retest only if you or someone close to you is obsessed over it. Love wisely and well from now on. Cheers. ...Read more

Are HIV RNA and HIV PCR the same tests? How soon after potential exposure can you get a conclusive result?

HIV viral load tests: The short answer is 'yes' -since HIV-1 is an RNA virus. We quantify how much virus is there per drop of blood by using PCR technology (polymerase chain reaction if you must know). These days, the tests are extremely good -so after an exposure, this kind of testing could pick up positive results within 2 or 3 weeks. If you think you've been exposed, see an ID doc immediately-they could help w/ meds ...Read more

Accurate but...: While the tests you have taken are good, the are not fool-proof. The standard is to retest at 6 months. This gives your body time to form antibodies. Be careful. ...Read more

Repeat in 4 months: You are in all likelihood free of HIV, just to make sure repeat the test in 4 months. 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. ...Read more

If 1hiv PCR RNA Quant test negative at 40, 105 days, is that enough to understand person has not got hiv?, or need more test on 6 mon? And What tests?

Probably enough: The definitive test to show no HIV infection is a negative antibody test and that should be done a minimum of 6 weeks after intercourse but usually more like 3-6 months. However if a pcr test is negative at 1 month and 3 months that's is essentially conclusive that you are negative, but you should have the Elisa and western blot antibody tests to be sure. ...Read more

All antibody tests negative at around the 10 week mark except for RNA PCR test which says RNA detected, below 20 copies/ml instead of undetected.

All antibody tests negative at around the 10 week mark except for RNA PCR test which says RNA detected, below 20 copies/ml instead of undetected.

Unclear question: If you are concerned about HIV tests, a negative result at 10 weeks after exposure is not definitive. You should repeat the tests at 6 months after exposure. Wish you good health! ...Read more

HCV+: Hcv+ genotype3, RNA pcr of 1730256 iu/ml refers to your viral load or how much of the hepatitis virus you're carrying in your blood. Your number is toward the high end of the range. You have normal lft's though. It's more alarming that you're hep c positive and are still having unprotected sex, unless your partner is already infected.

Is 59 days HIV combo + PCR RNA test neg conclusive? Some docs say yes, some say no and need to be tested at 3,6,12 months. What is correct? Some org say 12, 13 lots of confusing info Please answer!

The 3,6,12 is old: based on data that was purely antibody; even the CDC website screws that up. "HIV testing may be concluded 4 months after exposure " http://nccc.ucsf.edu/wp-content/uploads/2014/03/Updated_USPHS_Guidelines_Mgmt_Occupational_Exposures_HIV_Recommendations_PEP.pdf Thing is, nobody including me, believes you have ONLY ONE EXPOSURE lifetime. So, the real situation is to be tested about every 6-12 mo ...Read more
