HIV testing in the United States?!
Question: HIV testing in the United States!?
Many of the questions here seem to come from people who have been given a "positive" result of an ELISA test for HIV, before a Western Blot has been performed!.
If this is the case, it strikes me as a remarkably stupid thing to do!. It causes an enormous amount of unnecessary anxiety, given that the majority of positive ELISAs from low prevalence populations are false positives: a diagnosis of HIV can only be made on repeatedly postive ELISA PLUS Western Blot!.
In Australia, all positive ELISAs are automatically referred on for Western Blot before results are released!. If the WB is negative, the test is reported as "indeterminate - please send another sample after four weeks"!.
Is this what happens in the US too, or am I misinterpreting the questions I see here!?Www@Answer-Health@Com

As some one who does HIV testing!. With the use of Rapid Testing where we can give results in 20 minutes the test is only an Eliza test!. If we have a preliminary positive it is automatically followed up with another test where an Eliza is done first followed by a western blot!.
The reasoning for this is when we first started testing over 75% did not come back for their test results!. With the rapid testing you can give a result right then and there, so a much higher return on knowing a person status!.
If there is an indeterminate the person could be seroconverting and we ask to follow up asap!.
I know of some false positives, this was before when we sent the tests to a lab to process!. Due to a careless procedure in the lab a "splash" went from one slide to another to create the false positive!.Www@Answer-Health@Com

Frankly, I'd be more freaked out if someone refused to release my results and referred me for another test!.

Where I work, we perform rapid HIV tests!. It is an ELISA test, but people are given there results in 20 minutes!. If the ELISA is positive, we give our patients what we call a "preliminary positive" result!. We explain to them that the ELISA test isn't 100% acurate (however, it is 99!.7%), and that we must draw a confirmatory Western Blot before they are officialy diagnosed with HIV!.
Here, and indeterminate test means that at least one of the HIV bands are present, but there are not the three needed to make the test positive!. If the WB is negative, the person is considered negative, unless they have a viral load!. If they have a negative or indeterminate WB with a positive ELISA and a viral, the person is usually sero-converting!. In this case, we wait two weeks and then repeat the WB!.Www@Answer-Health@Com
