Enterovirus Rna Ql Pcr
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
Is my 8 wks 2 day PCR RNA + 4th Gen test negative conclusive for HIV infection after vaginal exp? Or do i need to test after 12 wks or it has to be after 13 wks? Pls answer, Thanks for any response
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

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
