Is 4th Generation Hiv Test Conclusive At 8 Weeks
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
99.8%: A WHO evaluation of five tests found that each had a sensitivity of 100%.2 A French evaluation of twelve tests found that nine had a sensitivity of 100%. Two tests did fail to identify a single HIV-positive sample (of 669 tested), and were judged to have a sensitivity of 99.8%. These tests were the Vidas Duo and Enzygnost HIV Integral. The samples missed were of subtypes F and C.3 ...Read more
It's conclusive.: The p24 antigen is a viral core protein that appears in the blood as the viral RNA level rises following HIV infection. The test turns (+) 5-7 days after viral RNA appears in the blood. It is 89-100% as sensitive as viral RNA.This assay detects a level of antigen that approximately corresponds to an HIV RNA level of 30,000 to 50,000 copies/mL . ...Read moreSee 2 more doctor answers
Took a HIV PCR at 7 weeks , HIV RNA at 17 weeks and HIV antibody at 13 and 16 weeks . All negative . Is it conclusive ?
1.How reliable, accurate second generation antibodytest at 6 week post exposure?
2.How reliable, accurate pcr plasmatest at 8 weeks if viral load low
Together, 100%: 1) Probably around 95-98% 2) Probably 95%. The combination of the two tests is 100% proof you don't have HIV.

Good luck and stay safe. ...Read moreSee 1 more doctor answer
Very accurate at 25: days(approx 1 month).. You should get tested again at 6 months to be sure. ...Read more
Test accuracy: Every test we do has a margin of error, due to both the nature of the test itself or how people behave when they collect samples, and the biologic variation between people. That said, the antibody tests for HIV perform quite well and in the setting of a suspect exposure are largely conclusive. However, the nucleic acid tests are far more specific than antibody-based tests can be. ...Read more

Very reliable.: It's recommended to repeat HIV test on the 12th week or 3 month window to account for a delay in the production of antibodies.If there is a higher risk of getting hiv, it's recommended to repeat the test after 6 months.Take care! http://i-base.info/guides/testing/test-accuracy-results-and-further-testing. http://www.ncbi.nlm.nih.gov/m/pubmed/15967238/ http://hivtest.Cdc.Gov/faq.Aspx#exposure. ...Read more
There are several ways to detect the HIV virus. The first is by antibodies. This includes eia (enzyme immuno assay). The rapid HIV tests are these types. The second way detects proteins on the viral coat (western blot). This is a gel plate electrophoresis. Thirdly there is pcr (polymerase chain reaction). This detects and amplifies dna allowing a viral ...Read more
