Popular Science: How a 99.99% Accurate Test Can Be Wrong Half the Time

An article in the July 2002 issue of Popular Science magazine
with no risk factors. Here1s the text from page 78: HIV testing is 99.99 percent accurate, a doctor might tell his
patient. That suggests that if you receive a positive result, you almost certainly have HIV. But this is not necessarily the case.
The chance of a straight man with no known risk factors
contracting HIV is roughly one in 10,000. That is also the rate at which an HIV test returns an incorrect result. So if 10,000 men in this low-risk group get tested for HIV, an average one positive will come back from the man with HIV, and another man will test positive even though he is not infected. Thus, in our statistically perfect world, only one of the two men who test positive actually has HIV. 50 percent of positive HIV tests in the low-risk group turn out to be false.(2)

The article incorrectly assumes that HIV tests can diagnose HIV infection and that the claimed accuracy rate of 99.99% has been established through careful scientific studies.

In fact, HIV tests have not been approved by the US Food and Drug Administration for use in diagnosing HIV infection, and all claims of test accuracy are based on estimates and assumptions.

That is why they do multiple other tests if you test positive. It is done to eliminate false positives in those that get a false pos. on a elisa. Maybe you should do more resurch and get all the facts.

Do you really think 'more' unreliable tests suddenly create a reliable result. You need to study basic statistics.

In fact, HIV tests have been approved by the FDA for use in diagnosing HIV infection.

He lies, because he can't face the truth.
