western blot - HIV Prevention Message Board

Please someone may know....

I read that Western blot done in people with only 6 to 7 weeks into the window period can provide a false positive or indeterminate. Is this true?

I had blood drawn today and the doc said they do both ELISA and Western Blot, and then just as got here I bumped in the to this information about Western Blot.

I thought this test was the most reliable one together with the ELISA.

Westenr Blot is a highly sensitive test. It is used as a confirmatory test for this very same reason. If an ELISA comes out negative, labs do not do WB, because there is a chance of a false positive.

Both tests taken at 6-7 weeks may not return reliable results. It is recommended to test at 3 months from possible exposure. What you took can be considered a "baseline" test set. If you were to come out positive on this, you would still need to test at 3 months/13 weeks to confirm for sure.

HIV tests are very inaccurate. I wouldn't trust them either, at all. Other STD tests work, but they don't know what the hell they're doing when it comes to AIDS. If you get a positive result, don't sweat it, it's probably wrong.

Cor- to get an accurate result, the western blot is only run after 1-2 positive ELISAs, so used with the ELISA it is the most accurate and final test to confirm HIV status. Because it is highly sensitive it is only used AFTER a +ELISA, so there is no risk of false positive, as not ALL tests will be positive UNLESS there is HIV anitbodies present. They will ONLY use a Western Blot after an ELISA has shown positive. As for the time you are talking about, 6-7 weeks is NOT a conclusive result, you should be tested at 12-13 weeks for a conclusive result.

Scapegoat-Where do you get the information from that HIV tests are inaccurate and probably wrong. I read anothe post, and you made it seem as if you believe HIV doesnt even exist. Why? 20+ years of research is wrong? Is this some kind of government conspiracy, or maybe something manufactured by the drug companies to sell drugs? What about the people in Africa who are affected, or babies who are infected from their mothers, how do they get HIV and AIDS? Just curious.

I completely believe that the whole AIDS thing is a crazy hoax. I have done a lot of research on it, there are plenty of books, journals, testimonials, etc. that have made me think twice about what we're being spoon-fed. It's quite amazing actually. In Africa, most of those people are also being diagnosed with Malaria, Cholera, severe dysentary, tuberculosis, etc. These people are obviously sick, but when you don't even have clean drinking water or nourishment for your body, what do you expect? Health? Doubt it. Those people are dying, but its not from an epidemic of one particular boogey man disease. I have never seen anyone get better after taking their cocktails of drugs either. Remember Magic Johnson? Stopped taking his meds and had a "miraculous recovery". When you want to get to the bottom of anything, follow the money trail. Do some research if you care. I can't preach to the whole world. The info is out there and if your life is at stake, maybe you ought to start reading up.
