Pertussis In Nasal Swab Pcr Test
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
A bit too early: The exact time for reliable chlamydia testing by NAAT isn't certain, but 3 days probably is a bit early. A negative result would be somewhat reassuring, but probably not conclusive. It would be safer to wait until 5 days or so, unless there is some urgency (e.g. if you have abdominal pain or other symptoms of a complication like PID). ...Read more

When the hiv test is conclusive?.what causes repeated perianal fungal infection?last hiv test 14monthes postexposure.is negative?
No worries: Every HIV test that exists, anywhere in the world, is conclusive by 3 months. The most commonly used tests are conclusive by 4-8 weeks. For sure your negative result at 14 months proves you don't have HIV, no matter how high risk the exposure (and if not reexposed), and no matter how typical the symptoms. Entirely healthy people often get perianal fungal infections; it's not a sign of HIV. ...Read more
I did a DNA PCR test for HSV & i got the result: -humanes herpesvirus-dna ((typ 7, pcr) (eb) : negative limit of detection:100 copies/ml.So i'm clean?

+ gonorrhoeae DNA amplification test, but, neg. Amp RNA test(source urine). Do they have gonorrhoeae? Is one test more reliable?
Complicated: Although these tests are very sensitive there are false positive results because of the potential presence of other benign species of neisseria. If you had to compare the two it would be without much relevant data. Bacterial culture will provide both a definitive diagnosis and allow determination of antibiotic sensitivities. ...Read moreSee 1 more doctor answer

What is the accuracy of HIV testing (antibody and antigen) 6 weeks post PEP? I had all tests (Neg) including the pcr rna test at 22 days post pep.
HIV testing & RNA: Read the CDC updated recommendations on HIV testing. The rationale for this test being available is that HIV RNA is detectable in plasma before antibodies. A safe approach is to be tested after the eclipse period after potential exposure when no RNA nor antibodies to HIV can be detected. The RNA test is effective around 10 days after infection but seroconversion to antibodies may take 3 months. ...Read more

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
