Avatar m tn , but when I looked at the method use, it was P24 (par Elisa). Immediately, I checked on the internet and found that P24 is used only for early HIV test (around 2-4weeks) and will fade away after that. Does P24 still use to detect HIV after 1 year and half? My lymph nodes are still everywhere, neck, armpit and groin, and I also have serious skin problem with my knee and I feel not well when I sleep at night and noon. Pls response as fast as possible.
Avatar m tn PCR DNA test is not a diagnostic test. You took the ELISA to early. The window period is 3 months. Most people will test positive at 6-8 weeks. You will need to take a conclusive test at 3 months post exposure. This story sounds just like another guys that was posted recently.

Avatar n tn Usually a block is performed to determine if there is damage to the sympathetic nerve chain and if it is the source of pain. This is a diagnostic test primarily, but it may provide relief far in excess of the duration of the anesthetic. I had a very similar diagnostic test for my SIJ. It diagnosed my severe SIJ Dysfunction beyond doubt. Nick is correct that this site does not tell you how to obtain narcotics but certainly for pain sufferers we make suggestions on who to consult.
Avatar n tn If the Elisa is positive (and obviously so will the PCR) then it means she has had it before she met me [ie. her elisa positive, me elisa negative] If the PCR is positive and Elisa negative then she has had it for a short period. She could have infected me. It will also prove her claim that her past Elisas have been negative. I will be able to accept such an outcome. I will then have to test the previous ladies to show it is her that must have contrated HIV some point over the last few months.
Avatar n tn and I had an ELISA test was negative but before that test I did a test with ECL and it had a reactive 14.47 . I am worried ... which one of those test is more accurate. is ELISA and western blot similar . how long does western blot take it progress ?? does it a month..or less than that??
Avatar n tn Dear Doc (and forum readers), About a week or so ago I needed to get a medical check for work. When I got my results back, I was shocked to be told that the Elisa test came back as HIV reactive at 1.52. They tested it twice. I really have no idea what that number stands for, though. I don't have sex. No girlfriend. And I don't sleep with street workers. As far as I can remember, I have not come into contact with blood (except when killing mosquitoes).
Avatar n tn Negative...conclusive. You don't have HIV.
Avatar m tn I was wondering if someone would explain me how are the Elisa test classified and how do I know what generation its. Would anyone know what generation Quest Diagnosis Work with?

Avatar n tn t studied about antibody testing since the tests that matter are the confirmatory vir load tests as the antibody test is only a screening test. It does seem that unfortunately testing positive for mearly the antibody apparently bars people to employment in places like the UAE United Arab Emirates where the original poster is wanting to work. So glad we can work here in the U.S.
Avatar m tn i have got an elisa test done for hiv 3 years after exposure. my test confirmed that i was negative. do i need to get retested or can i be assured that i am hiv negative. and yeah thanks for answering my previous questions, it helped me a great deal. you all are doing a great job , thumbs up....
Avatar n tn Does ELISA and WB test are also part of rapid test?and how accurate is rapid test if done after 6 weeks or 3 months?
Avatar n tn curious where did you find this graph?
Avatar f tn I haven't posted in a while and am wondering if anyone can help me with this because I can't find this answer anywhere... How does Oraquick work? I know it checks for antibodies and I know there are antigens on the test. My question is how do they create the antigens?Do they create a whole virus and then pull the antigen out of it? Where on the test are these antigens located? Are they on the T line? I have many fears regarding hiv but one of them is this test!
Avatar n tn Dr. EWH, My girlfriend and I tested for hiv and my girlfriend got the result back today. The result says "negative" and in "reference range" column states "nonreactive". It says that test was "hiv 1/2 ABS /W RFLX CONFIRMATION". It also says hiv-1/hiv-2 ABS ELISA. Does that mean ELISA was done first and then confirmed with something else? Or does it mean that it was confirmed by another test because the result of ELISA wasn't good?
