Avatar f tn There are different HIV antibody tests. One test is the ELISA (enzyme-linked immunosorbent assay). If the ELISA test is positive, a second test called a Western blot is done to confirm the result. The Western blot takes longer to perform and is more expensive than the ELISA test, but it is more precise.
Avatar f tn The enzyme-linked immunosorbent assay (ELISA) screen is often the first test performed. It tests for HCV antibodies that the body has produced in response to the infection.
Avatar f tn Hiye, this may seem a silly question but is the Elisa test that is used for HIV the same as the Elisa test used for rheumatoid arthritis?.. Is the Elisa just a standard antibody test that is not disease specific and if reactive then a specific test is used?..
Avatar n tn subsec=2 It says that you should do another test inmidiatly, so go to the closest testing place, and get another rapid test so you can have a better idea, DO NOT HAVE A Western Blot, unless you have a positive elisa or rapid test, and inconclusive or indeterminate is not a positive, if you continue having indeterminate results on rapid test, get an Elisa and if the Elisa is also indeterminate, seek for and Hiv expert near you to help you on wich test is better for this case, rapid and elisa tes
Avatar m tn i have no symptoms untill now, i did Elisa test 52 days after 1st time and 20 days after last time and today it´s been 2 months since 1st time (the day i saw the blood) and 1 month after our last time. i live in africa, the doctor said that the elisa test i did is excellant and it could detect antibodies even 1 week after last time.
Avatar n tn Should i test in a lab, or is a rapid blood test also reliable 12 weeks post potential exposure?
Avatar m tn Of course ELISA test can be indeterminate. No an ELISA test is not that much different than a Rapid test. One takes a machine to process while the other doesn't.
Avatar f tn My daughter was sexually assaulted and took an hiv dna pcr test and an antibody test 32 days after possible exposure. I know the hiv dna pcr test is not a diagnostic test but since she took both tests shouldn't that help to alleviate some of her anxiety? I was told the dna pcr test is pretty conclusive after 28 days. If the dna pcr test is so unreliable, why is it used for testing for blood donors in my area to help shorten the window period? Thanks for any responses.
Avatar n tn My lab report only mentioned Western Blot ans negative. There was no mention of the ELISA test. My question is was an ELISA test done and then it was confirmed with a Western Blot test - or was the only test performed the Westerm Blot since this is the only test that showed up on my lab results. From what I have read, a Western Blot test will not be performed unless there is a positive ELISA test. This has me concerned as Western Blot is the only test on the report.
Avatar m tn ​The Herpes Simplex IgG test is performed using an ELISA (Enzyme Linked Immunosorbent Assay) test kit manufactured by Euroimmun Diagnostics (Germany). This ELISA test provides a quantitative in vitro assay for human antibodies of the IgG class against HSV 1/2 (group specific) viruses in serum or plasma.
Avatar m tn ELISA tests do have occasional false positve tests. The ELISA is an inferior tests and almost no matter what the result, I expect you will have continuuing questions. It would be good if you could arrange for an NAAT.
Avatar m tn is an elisa at 51 days accurancy (reliable, confident) independent of the generation test ? thank you p.d : excuse for my english , i live in venezuela This discussion is related to <a href='http://www.medhelp.org/posts/show/247100'>3rd Generation HIV test</a>.
Avatar m tn As we all know ELISA or antibody test is the primary test taht is performed for HIV testing.If this is opsitive then comes WB.Is it possible that ELISA can give false NEGATIVE like false positive ?If yes what will happen then ?
Avatar n tn The DUO is an ag+ab test.The elisa is just an antibody test.You never had a risk to begin with.You need not be concerned about testing unless you have had a genuine risk.
Avatar m tn Just came from my doctor and found out: I was tested with HSV 1, 2 Comined Ab Screen IgG (ELISA) and the result was 2.12 (which indicates 'Detected' for a range greater than 1.1). The test was performed by Arup Laboratories. I don't think they tested me for HSV 1 and 2 separately. My doctor told me I have herpes and I am freaking out although I don't have symptomatic symptoms experience. However, upon reading the thread here, it says that this range may be false positive.
Avatar m tn At that point i went crazy. I went to a infectious disease specialist and he performed another Elisa test and a Combo test (7 and a half weeks post exposure). The elisa came back positive again, with the same results as the last test (that was performed 2 and a half weeks before the second test), with no antibody dinamics (no increase in the amount of antibodies compare to the 1st test). The Combo test came back positive as well (because of the Elisa), but the p24 antigen was not detected.
Avatar m tn However I still freak of it, I just want to know is there any possibility that I catch HIV? Do I need to have the RNA test? What is the window period of ElISA test? Thanks.
Avatar m tn Yes, you will take an elisa test or some forum of antibody test and if positive another WB will be performed.
Avatar m tn ELISA blood test is more slightly reliable and is the prefered method. But you should have had a WB after the positive tests. I would not doubt a negative ELISA blood test.
Avatar m tn I retested after 10 years with HerpesSelect 2 IgG Elisa and it came back as non-reactive. Q2. How accurate are HSV Elisa tests in correctly identifying negative HSV1 and HSV2 results? I had ordered an online home test kit where I had collected my blood on a blood card and ship it to the lab in another state. I heard they miss huge numbers of HSV1 and 3% of HSV2 results. P.S.
Avatar n tn Here is my story 6 months back(in sep 2010) i had sex with a prostitute but unfortunately my condom got ruptured and i got tested 3 months post exposure and now 6 months post exposure and test results are negative(test was performed using 3rd generation elisa kit) and all my symptoms are muscle pains.still i feel these muscle pains especially at the lowe part of my body (both thighs and calf's). Here are my test results 3 months test:0.32(i.e negative) 6 months test:0.50(i.
Avatar m tn My question are....... is there any chance of getting HIV through old but cured eczema (that area is still black ) ? How accurate these Elisa test are ? I'm still having muscle pain, muscle twitching, and joint pain with a dry cough after 75 days of first incident. I had a history of getting cold frequently as my immune system is not strong enough. Now please tell me the chances of getting infected with HIV.
