Avatar m tn Has the HIV PCR RNA or HIV PCR DNA test been approved by the FDA for diagnosing HIV yet? Or is the 3rd and 4th generation antibody tests still considered the "gold standard"? Thanks for your input and time!!!
Avatar m tn Under what circumstances is a PCR-RNA and P24 test used and does that give you a more conclusive result?
Avatar m tn I would also say that I'm not sure which disease to test for. I presume it would be a multiple disease test. My main question would be which type of test is best... internal swab or blood test?
Avatar m tn I read the article, and it seems that they are talking about drug resistance screening, not HIV screening in general. So those cases are about people who have viruses that would test incorrectly on measurements seeking to treat their HIV infection. But, those people would still test positive under antibody ELISA tests. Hope that helps.

Thanks immensely for your time and sorry about the length of this email. Sincerely, Chocabo PS I'm really impressed with the work you do on this website and the help that you provide to hundereds if not thousands of people. Is there any way I can donate?

Avatar f tn I will having a hiv test with cmia methods generation but I'm confuse there are some opinion that said 6 weeks better and the other 8 weeks.
Avatar n tn everything came out negative at 5 months. later got tested for hiv with rapid test where they use oral fluid and this was negative. this about 6 months after last sexual activity. is this conclusive and is rapid test reliable? read on aids website that a series of tests is recommended at 6 weeks, 3 months, and 6 months.
Avatar f tn I know that this forum has said that unprotected cunnunglus is a very low risk factor to contact HIV. However as the forum knows people still are nervous and worried. I had a HIV 1&2 antibodies test thinking that I was 90 days out from contact. The woman that I was with contacted me saying that she gave me the wrong date. This meant that I was only 55 days out from being with this woman. My doctor said that the HIV 1&2 antibodies test is at least 90% accurate.
Avatar m tn - HIV 1 and 2 antibodies and p24 antigen test (HIV DUO or HIV Combi test) This HIV test is licensed in the EU for use after 28 days after a possible exposure. It is probably much better than this and will probably identify the majority of newly infected HIV positive individuals at between 14 and 21 days. This HIV test is referred to as a fourth generation HIV test. Certainly in our clinic we have had many new diagnoses of patients using this HIV DUO test combination in that time frame.
Avatar m tn In this context neither of us has heard or read a credible scientific report on any person who acquired HIV and took more than 8 weeks to develop a reactive HIV antibody test. Similarly I have asked numerous colleagues at scientific meetings if they are aware of any instance in which it has taken more than 8 weeks for a test to turn positive and the answer for over three-4 years, at least, has been uniformly no. Dr. Handsfield's experience is similar. Bottom line.
Avatar f tn I had an influenza vaccine done last week and I am supposed to get an HIV rapid test or oraquick test done tomorrow since it's 6 weeks after my exposure. I am so nervous because I know the one i had done at 4 weeks didnt mean much. Now, my worry is that I have a false result tomorrow and worry myself to death.
Avatar m tn Chemiluminescence . AT 15, 30, 43 DAYS AND IDENTIFICATION OF HIV -1 proviral DNA METHODS: Polymerase chain reaction polymerase chain reaction and nested polymerase ( nested PCR) endpoint. AT 30 DAYS. CONCLUSIVE, NEED TO RE-TEST? SHOULD I GET A 3RD GENERATION TEST AT 90 DAYS?
Avatar m tn You don't guess at HIV, you test. She can test 3 months post exposure to obtain a conclusive test result. Please do not start multiple threads. Keep all your posts on one thread.
Avatar m tn Can RNA-PCR test detects the HIV infection earlier than HIV if yes then how early

Avatar n tn no test was hiv combi .ag/ab.value 0.07. cut off value 1. test result negative. also tell me do that method effect my test results thanks in advance.
Avatar f tn Hello guys, About 6 years ago i did a sex without condom with prostitute it was my first time and it was not last longer than 1 minutes and it is only exposure i had then i got test at governments health center at 2 months 4 months and 1 year all negative the test using 3 different blood rapid antibody test(one test with 3 rapid methods ) 2 month (all 3 rapid blood test negative 4 month (all 3 rapid blood test negative) 1 year (all 3 rapid blood test negative) This is part I don't unders
Avatar n tn Their are test that look for the actual virus which are early detection type methods. I believe it is HIV Proviral Test which you can take at 28 days. Oral Sex is considered low or even in some circles no risk to hiv. I have been told that our saliva has an active agent that breakdowns the virus and gives us protection from it. As long as you are wearing a condom for vaginal or anal sex then you have protected yourself from getting hiv. HIV is a fragile virus... I hope that helps.
Avatar m tn hi i have perticipated in and un protected sex..condome broken..i have tested with tis test at day 21 from exposure PCR DNA at day 35 from exposure P24 COMBO DUO at day 60 from exposure P24 COMBO DUO after 3 months 4 months and 5 months with HIV ELISA 1 & 2 ANTIBODY TEST all these tests came back nagative and non reactive.. my doubt is...
Avatar n tn Most of the discussion here on window periods and test reliability has referred to 4th generation HIV tests. I received an HIV-negative result from a 3rd generation MEIA test 45 days after a possible exposure. What approximate percentage confidence can I have in this result? Thanks and regards.
Avatar n tn Hi Last week I underwent EDP (Early Detection Profile) test for HIV as I doubted I might be infected after the unprotected sex. I had this EDP test ten days after the unprotected sex. Now I got the result which is printed below. 1. Infections: HIV-DUO by CMIA (IV th Generation test – NON REACTIVE (0.1) 2. HIV-p24 antigen detection by ELFA – NEGATIVE 3. Nucleic acid detection HIV-proviral DNA by Real time PCR - NOT DETECTED 4.
Avatar m tn the first blood of blood is not wiped before withdrawing it, will the test result (non reactive) be still valid? Manufacturers of Alere Determine HIV Combo Rapid Blood Test advise to wipe the first drop of blood after finger-stick to avoid tissue fluid.
Avatar n tn pdf Page 27 Current methods for the detection of HIV may not detect all infected individuals. An ARCHITECT HIV Ag/Ab Combo test result that is nonreactive does not exclude the possibility of exposure to or infection with HIV-1 and/or HIV-2. Nonreactive results in this assay for individuals with prior exposure to HIV-1 and/or HIV-2 may be due to antigen and antibody levels below the limit of detection of this assay. UK testing guidelines.
Avatar m tn Because a DUO test doesn't check for HIV 2 by antigen and isn't appoved to give a conclusive test earlier than 3 months.
Avatar f tn My boys from Indonesia, before I say accepted the love, I have sex without a condom in the month 8, 2014, the base of my penis hose week itchy and irritating to the skin, but it hurts me less ignored and repeat the action on 20 December 2014 with a woman another, how the hose, small meat pile arise in areas that itch (like I said earlier that in the base of the penis where the growth of hair) from where I was afraid with HIV, on 11 February 2015 I did a test in a private clinic negative result,
Avatar m tn Any antibody test at 4 weeks is 90% reliable. The antigen part of the DUO makes the test almost conclusive for the HIV-1. Detection of antibodies for HIV-2 only relies on the antibody portion of the test. At 4 weeks it is NOT conclusive for HIV-2.
Avatar m tn hello Dr I have a 3 methods tested by the ARC HIV ag / ab, determine HIV and HIV Com all negative at 2 month. I have used PEP for 4 days but I stop because I have side effects. At 5 weeks I have a tested by combo it was negative. I can feel secure and not think about HIV??
