Hiv 1 Screen 4 Th Generation Wrfx Non Reactive
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
Does a negative hiv-1 western blot at 6 months (no ELISA was completed only wb) indicate no hiv-2 as well? Or should I screen again?
Western blot: Most sensitive test available. Negative excellent.Get a more detailed answer ›
I just had an HIV 1/2 eia antibody screen w/ reflexes. Can you explain how this test works? Are there any better tests?
Viral Testing: To test for many infections we look for antibodies (your body's reaction to something new or foreign). In the case of HIV infection these antibodies can take three to six months to be positive on a test. This old fashioned test is a reliable and common screening tool. But, it is not the best test if one is possibly exposed. We now send HIV genetic tests which can be positive by day 21 post expos. ...Read more
I took a HIV-1/2 Fourth Generation test and the results were reactive. Week later my HIV RNA, QL TMA came back negative. What does this mean?
I had 7 hiv duo test at 3rd 4th 6th 8th 12.7th 13.3 th 15th 1) antiobdy 9.5 week 1) hiv 1 rna pcr qualitative at 14.5 week All -Non reactive hiv?
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
Is 4th generation ag/ab conclusive for BOTH hiv-1 & hiv-2 after 6 months (& multiple tests before this) of unprotected sex? Is further testing needed?
I went for HIV 1/2 & p24 Combo test (CMIA) Test on 32nd day after HIV exposure and result was non reactive. 1). How much I can trust these result?
HIV testing: Nope. That test is not valid until three to six months after exposure. ...Read more
Hiv 1/2 eia non reactive at 8 weeks and again at 23 weeks. How confident should I be that I'm HIV negative?
6 months window: Depending on the time of exposure about 6 months window for seroconversion is usually sufficient. However if exposure has significant extending testing to one year may be more reassuring. ...Read more
Report value result is cut of index 0.553 reference range cut of index 0.90 non reactive negative for HIV 1 and HIV 2 what is meaning of 0.553 n 0.90?
This sounds like a good question. This is the way antibody testing is reported by labs when searching for viral infections.
If the antibody response is not acute enough one is not considered to be infected.
Any further testing in this case should be based upon risk and recent experience. One can also be tested by searching for the genetic material of the HIV virus instead of antibody testing. ...Read more
Hi I had HIV 1&2 lab test and the results are non reactive (0.347) cutt off rate is 1.0 test performed my ECLIA, I m so worried is it higher. Please help me?
Likely negative: ELISA is highly accurate, almost 99%. So please be reassured. Repeat the test in four weeks or so to ensure it remains negative. If you have not been sick with a fever, rash, sore throat, enlarged glands, chills, night sweats etc. In the last two months, then the risk of being infected in last two months is even lower. ...Read more
What does a nonreactive/neg HIV 1/2 AG/AB 4th GEN/RFL mean? Why does it say it does not exclude HIV and that seroconversion is variable?
For the lawyers: Nobody knows how often the new HIV tests turn positive "late" because nobody really knows who's done what other risky stuff and not told about it. I'd accept negative / nonreactive results if the usual time frame for the test has lapsed, be thankful for good health, love safely from now on, and share the memory of whatever happened as something to be treasured. ...Read more
Is 28 day result conclusive timing for a HIV neg test - 4th gen duo (HIV 1 & 2 incl P24)? On web and Dr's on health tap, conflicting responses.
I recently got my HIV test results. They are kind of scientific. Can anyone explain these in english for me? Hiv 1/o/2 abs-index value <1.00 <1.00 hiv 1/o/2 abs, qual non reactive non reactive
It is HIV: Hiv is human immunodeficiency virus--type 1 or 2...Does not matter which type...It is transmitted via sexual/vaginal/anal intercourses, needle sticks/sharing, and mom-child transmission during pregnancy/birth (vertical transmission)...Kissing and simple touching does not transmit the disease... ...Read more
Yes: While it is possible, it is very uncommon and infrequent. ...Read more
Is 28 day result conclusive timing for a HIV neg test - 4th gen duo (HIV 1 & 2 inc P24)? On web and this forum, conflicting communications.
Definitive. A positive result would be definitive but a negative one, this soon after exposure does not rule out infection. Repeat the test a 12 weeks and 6 months after exposure.
Wish you good health! ...Read more
HIV 1&2 P24 Combo (CMIA) test done on 13th day. Index value is 0.1 and non reactive. Symptoms. White patches on tongue so far. How reliable is my test?
Pretty reliable: This test result is about 80-90% reliable in showing you did not catch HIV 13 days previously. Have another test at 4 weeks to be 100% certain. It is much too soon for "white patches" on your tongue to be due to a new HIV infection; they have nothing to do with HIV or your possible exposure to it. ...Read more
HIV 1&2 P24 combo 13th day. Index value 0.1&non-reactive. Oral Candiasis (tongue) on14th day. Is this ARS? No other symptoms so far. How reliable is test?
Very reassuring: I think this is a duplicate question, same answers. Oral candida is not likely (not the same as white coated tongue). But even if candida, it is too soon for it to be from an HIV infection caught only 2 weeks previously, and is never the only sign of ARS. Your test is about 90% conclusive that you don't have HIV. Have another combo test at 4 weeks to be certain, but in meantime really no worries. ...Read more
