Hiv Ag Ab
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
Rapid results: There are mini ELISA kits available with results in 15 minutes. and they are good! You could also go to your local health department to be tested or doctors office. If you ask me though..don't be concerned with the rapidity that you get the results back because you may sacrifice accuracy. Just go to your doctor and have them run a Western Blot or conventional HIV screening test on your serum. ...Read more
I had a hiv ag ab combo 4th gen test done at 3 weeks 6 weeks and 19 weeks are they conclusive still very scared?
4th gen HIV tests...: ...are 100% conclusive any time 4 weeks or more after exposure. There is no basis for continuing to be frightened you have HIV. Assuming you haven't been reexposed more recently, your 6 week result was conclusive and your 19 week test unnecessary. Stop testing and do your best to move on without worry. Also test for gonorrhea, chlamydia, and syphilis if not done, much higher risk than HIV. ...Read more
I got a HIV test yesterday after 12 months of the risk. The test said: HIV Ag/Ab Nonreactive. What does this mean?
Hiv ag/ab combo : non reactive, patient s/co: 0.23 (ref : reactive >=1.0 s/co). What does this mean. After 1 year of exposure.
I was wondering is it possible to have HIV and not be detected in the HIV ag/ab combo testing? Is there a dormant phase? And for how long of dormancy?
It depends...: The HIV antibody-antigen combo or duo test ("4th generation" test) is always positive by 4 weeks. If it has been that long or more since your last possible exposure, it is not realistically possible that you have HIV. Most people with HIV remain outwardly healthy for years, so it seems dormant. But not really. The virus is active, damaging the immune system and leading toward death if not treated. ...Read more
I recently had a neg HIV AG/AB 4th GEN RFL blood test. Why does it say that a nonreactive result does not exclude it?
Wondering in 2012 I did a HIV 1/2ab test came back negative, in 2014 I did a HIV ag/ab test combo came out negative do I need retest monogamous 3 yrs?
Can low lymphocyte count 1477 18% affect a neg HIV Ag/Ab test done after 4 mths.I read on the net abt people with low imunity that need six mths.plz h?
Is a HIV ag/ab eia and a hiv-1 Rna test conclusive at 5 months ? I also had a 4th gen test 3 months ago both negative. Blood was cold if that matters
With todays ultra sensitive modern ELISA tests, what use is the western blot for hiv? A few months ago i received a weakly reactive cmia HIV ag/ab test, a 4th generation HIV combo test, and this was followed by a negative western blot and a negative p24 t
False-positives: Screening tests are designed to be highly sensitive so they don't miss anyone with the disease. However, they can be so sensitive that they occasionally give a false-positive result. That is, the test appears positive for someone without the disease. The western blot, being time consuming and extra cost, is only used to make sure a positive is really a positive. Talk with your doc for more info. ...Read moreSee 1 more doctor answer
Hi, had HIV-1 rna pcr @ 5 weeks & 5 months. and HIV ag/ab DUO at 1, 2, 4 & 6 months. Do I need further testing for HIV or do I need HIV-2 pcr or did the DUO rule it out?, or is it too rare to worry about in MI? I leave in Novi, MI. thank you
I had an hiv mixed ag/ab detection test 4 weeks after exposure. Is this accurate ? It came back negative.
Nearly conclusive: The Ag/Ab HIV tests detect almost all infections at 4 weeks, but on rare cases it can take 6 weeks. If you had an especially high risk exposure (e.g. unprotected sex with a known infected partner, anal sex with another male), have another test at 6 weeks. Otherwise no worries. ...Read more
Hiv p24 ag ab combo test at 28 days, 42 days and 62 days, some are negative.Quanto to be safe after 62 days?
Not a good test: P24 antigen testing is not the best way to rule out infection. The most sensitive test is a qualitative viral dna test, not usually performed. At 62 days HIV elisa may well be positive, if you were infected. Because sometimes antibodies are not formed until 90 days, you can complement by HIV RNA test that can detect down to 20 copies per ml of blood. ...Read more
