i had hiv test hiv 1/2 eia AB with reflexes come back non-reactive

This answer was rated:

i had hiv test hiv 1/2 eia AB with reflexes come back non-reactive and was given a indeterminate result. I had a negative on last test about a year ago ten days from the collection when I got the result I immediately went to another medical facility and showed them the indeterminate result and asked for a new HIV screen they preformed the collection and all test came back negative should I assume the first test was a indeterminate and the negative on the second indicates I am negative

Did either facility perform a Western Blot confirmatory test?

If so, what was the result?

i dont know they just said all test were negative on rhw second one and the first did not indicate a WB was done

The usual testing protocol is to perform an initial test that is a screening test, such as an EIA or rapid test. The screening test is designed to be very sensitive, but not as specific. Therefore, if the screening test is negative, the negative result can be trusted without further testing. If the screening test is positive, then a Western Blot test is done as a confirmatory test. The Western Blot test is very specific. There are some conditions that can cause a positive screening test, but the Western Blot test will be able to determine if HIV is present. If the screening test is positive and the Western Blot test is negative, then the result is negative. If the screening test is indeterminate, either a repeat screening test can be done or a Western Blot test can be done. If either test is negative, then the result is negative. It is unclear to me why the first facility did not perform the next step, but since the testing at the second facility was negative, then the result is negative.


Of course, it is also necessary for a sufficient period of time after an exposure for any test for HIV to be accurate. There is a period of time after initial infection before antibodies can be detected, so testing should be done after a sufficient period of time.
