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

HIV NEGATIVE combo (antibody + antigen) tests at 4,6,10,13,14 weeks and PCR RNA VL UNDETECTED (14 weeks) white tongue, chronic pharyngitis. Am I HIV-?

HIV NEGATIVE combo (antibody + antigen) tests at 4,6,10,13,14 weeks and PCR RNA VL UNDETECTED (14 weeks) white tongue, chronic pharyngitis. Am I HIV-?

You are HIV negative: Listen, man. Stop doing this to yourself. Get to an otolaryngologist and see if you have a post-nasal drip, maybe heavy snoring without realizing it, or some actual serious illness. Try scraping the stuff off your tongue with a piece of dental floss; if it's still white patches, ask your dentist's opinion also. But please get over these HIV fears. Maybe even be thankful for having shared love. ...Read more

HIV NEGATIVE combo (antibody + antigen) tests at 4,6,10,13,14 weeks and PCR RNA VL UNDETECTED (14 weeks) white tongue. Risk: gay deep kiss. Am I HIV-?

You are HIV-neg: I hope this is good news. "White tongue" is usually bacteria, and you may be able to scrape them off with a piece of dental floss held tight. You can trust the test if it is your only exposure. I hope you're comfortable with your sexuality and that you're pleased to have shared a kiss -- guys of all orientations may enjoy perhaps kissing a buddy, and nobody's ever gotten HIV by kissing. ...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?

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

Stop testing!: You have been seriously overtested, especially for HIV. The 4th gen HIV tests are conclusive any time 4 weeks or more after exposure. All HIV tests after the one at 1.5 months were superfluous and a waste of money and time. The other tests also are conclusive and also didn't need to be done a second time. No matter how high the risk might have been, you can move on without worry. ...Read more

Probably cleared: The hcv viral load tests are not fda approved to confirm active infection, although this is how most doctors use it. If a repeat viral load in around 4 months is also negative, people are considered to have spontaneously cleared infection. ...Read more

My hepb serology hbasg +ve, confirmatory test hbsag-ve, hbcab, hbsab, hbeag, hbeab are all -ve, this is 3rd tym same result, am I infected?

My vote is...: No, based on the confirmatory results that antigens and antibodies are negative. As the surface antibody (HBsAb) is currently negative, one can ask his primary care for Hepatitis B vaccines, to acquire protection. However, if one was exposed recently, and got a new infection, he could be in the brief window period, if the HBcAb test was for IgG only (thus missing HBcAb IgM). His Dr. can explain. ...Read more

Not for HIV: It would help to know your risk factors for acquiring HIV, but, regardless, absence if viral DNA after 4 months followed by absence of HIV antibody at 5 months means that we're 99.9% certain you haven't acquired the HIV virus. However, you need to follow up with your doctor about the swollen lymph nodes. ...Read more

Be grateful, man!: You've been obsessing about this too long. Sit down and talk with your physician about fears. If you'll forgive my frankness, talk with him/her and some wise adults (maybe even dad) about your emerging sexuality and how you've explored. By your age, we've all made mistakes. Embrace being a man, decide how you want love to be for you, and cherish adult love while resolving to be safe ; kind. ...Read more

Oral sex with unknown, continuous 5month low grade fever, lymph nodes, sore throat, 107 da HIV eia negative HIV PCR RNA not detected, what other std?

NOT STD: As you have been told this is not an STD. But, it could be an infectious disease. That list is hundreds of possibilities long and will include testing for lymphoma, leukemia, other blood cell cancers, and all of the possible non-STD infectious diseases. It is time to sign off of the internet and to see your doctor for the appropriate testing or infectious disease consultation. ...Read more

CMIA 4th gen antibody screening test (not antigen) for hiv 1 & 2 @50 days is 0.15 non reactive.Is antibody screening without antigen accurate @7thweek?

Conclusive at 6+ wk: Official advice by many agencies is that stand-alone HIV antibody tests are not conclusive until 3 months. However, with the modern tests in current use, including the test you had, the results actually are conclusive any time 6 or more weeks after exposure. Feel free to have another test at 3 months if another negative result will help you get beyond your fears. But i really isn't necessary. ...Read more

Hiv (Definition)

Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more
