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

Can someone explain a PCR lab?

Molecular testing: Pcr = polymerase chain reaction. This is a very sensitive type of molecular lab testing in which tiny pieces of genetic material are amplified over and over again under controlled conditions to assess for the presence or absence of specific genetic material and/or to characterized that material. Pcr can be used for genetic testing, diagnosis of infections, cancer testing, and other things. ...Read more

Can hiv pcr detect hiv associated with  Hiv/FSGS?

Yes, but...: ...this is your 3rd or 4th question because of worry about HIV in what (from another question) was an obviously low risk exposure. You appear to be irrationally concerned, and having trouble believing or accepting repeated reassurance. There's no point in repeated questions; the answers won't change. Consider counseling; I suggest it from compassion, not criticism. Good luck and stay safe. ...Read more

How long after exposure to HCV does it take to test + with pcr?

How long after exposure to HCV does it take to test + with pcr?

A few days: No one knows for certain. If you shared needles, i know you will be wise enough not to do this again. If you had sex, remember it is difficult to transmit the infection this way. If you had some other kind of exposure, get tested but i would be surprised if it resulted in infection. ...Read more

What's the accuracy of PCR for HIV after one month of exposure?

100% if positive: Nearly all patients test positive for HIV RNA by one month following exposure. There may be false negatives if the virus is not yet circulating in a high enough titer, but a positive test is nearly 100% accurate. ...Read more

If PCR is positve and culture negative how do we go about it in tuberculosis?

If PCR is positve and culture negative how do we go about it in tuberculosis?

PCR can be false pos: False positive. If the suspicion for TB is high then a positive pcr should probably be treated. But if the suspicion for TB is not high, then the pcr is more likely to be false positive in this situation. No test is perfect, and you have to weigh the risks and benefits of both courses of action. ...Read more
