Is hiv-1-pcr quantitative and HIV RNA PCR quantitative same tests?can DNA PCR test be quantitative?
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

Hep B Virus (HBV) DNA Qualitative (Detection) - COBAS TaqMan , Hep C RNA Detection by Taqman detection will be conclusive on 47 days? Any retest need?
No: Both Hepatitis B and C viruses may be detected 30 to 60 days after infection by antigen detection or 60-120 days with antibody testing. Direct HBV DNA and HCV RNA testing can potentially detect infection earlier, within 2-4 weeks after infection, so being tested at 47 days post-exposure with a negative nucleic acid test for both is very likely to be a true negative ...Read more

Interpret hepatitis B panel results:
Hep B surface antigen (HBsAg) - Non-reactive, Hep B core Total antibody Anti-HBc Reactive, NAT Non-reactive?
Ebv panel. Ebv nuc antigen igg=157, early ag igg=12.7, EBV VCA igg=112, EBV VCA igm=10.6. Please explain. Concerned about spleen. Symp=fatigue/fog?
? Active infection: It's impossible for me to answer with certainty since i don't know the normal ranges your lab uses. If early ag & vca igm are elevated above normal this indicates active ebv infection.I don't know if it is acute or chronic without knowing your history. If chronic i see that as a sign of poor immune function.Immune-boosting herbs/supplements & IV vit c drips may help, but find why immunity is poor. ...Read more
Hepatitis c (HCV) antibody is reactive. The hepatitis C Recombinant Immunoblat Assay(riba) confirmation test is non reactive.Is antibody false positiv
Well : A positive hepatitis C antibody test with a negative or in a test usually is not a false positive that usually means someone had hepatitis C infection and their body cleared the infection and they are now immune to hepatitis C.

Hiv ab,1/2, eia with relx result repeatedly reactive. HIV 1/2ab differentiation w/refl hiv1 antibody negative hiv2 antibody negative. pos or neg hiv?
It depends: In a situation like this you have one positive test and one negative test. The lab should run a tie-breaker test (HIV RNA) to give you a real answer. Also, the first test may be an older test 2nd or 3rd generation) instead of the latest 4th generation) test. It also depends on if you have flu-Like symptoms. Seek help from a specialist in HIV who can help you understand. ...Read more
IMy HBV test results (red cross): Hepatitis B Surface Antigen: Nonreactive; Hepatitis B Core Antibodies: Reactive; HBV PCR: Negative. Do I have HBV?
Cured, but...: If a person's Hep B surface antigen is nonreactive, that means the lab does not find pieces of the surface of the virus. If her Hep B virus PCR is negative, that means the lab does not find the virus's DNA (genes). If the core antibody is reactive that means her immune system REMEMBERS being infected with Hep B. She is cured, but some viral DNA might be attached to her own human DNA in her liver. ...Read more

HBV test results: Hepatitis B Surface Antigen: Nonreactive; Hepatitis B Core Antibodies: Reactive; HBV PCR: Negative. Need any medication or vaccine?
Excellent question: and your story stumps many a doctor, often! :) a lot of the recommendations depend on - are you someone with risk factors for HBV? is this the first time that it has been checked? are your liver enzymes normal? are you about to undergo any procedures/ treatments that could put you at risk for HBV? If you have no sig risk factors, yes, I'd vaccinate you if there's potential for exposure. ...Read more

Is LABCORP "Hepatitis C Virus (HCV) Antibody Verification" test used as was used riba test for ruling out/in false positive hep C HCV antibody results?
HCV: Nowadays with polymerase chain reaction technology it is making "window" periods a less discussed issue. In my practice if I suspected a recent infection (say days to weeks old)..this test would show virons in your blood. Once this virus hits your bloodstream it explodes exponentially. Some people are fortunate that their bodies contain the infection..most do not. ...Read more

It's not really: a question of truth telling. No test is perfect: the proteins and reactants used in each test will respond to an individual's blood/biologic material, potentially, in a different way. Falsely positive or falsely negative results are not very unusual. You need to decide on a confirmatory strategy with your doctor. Retesting is necessary and an expert can help you weigh the evidence to decide result ...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
What is the window period for p42 antigen/ antibody dual 4th gen HIV test? And the window period for HIV RNA PCR test? When can it be conclusive?

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
Had HIV RNA PCR test done at 82 hours post exposure. I was assured if the results were negative, I was negative. Is this correct?
Took Truvada 3wks post exp. took it only 21 days. At 7, 8, 10, 11 and 13 wks did 4th G (7,10,13), PCR RNA(8), rapid(11) all negative. Conclusive?
To be on the safe side, get a HIV nucleic acid test at 6 months after exposure.
Wish you 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.

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

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
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.
