There are two different PCR based HIV tests. PCR-DNA and PCR-RNA. Of the tests you reference, if you click on their links to get a description, you will see four of the five are of the PCR-RNA variety. One of the four does not have a description link.
I'm not sure what the original poster's purpose was. It's kind of yelling that the sky is going to fall and not providing anything else. What's more, he references an article of someone who had a conversation with someone at the CDC - 'nuff said.

The PCR HIV test is not yet approved because it has primarily been used as a research tool. That doesn't mean it isn't any good. Only one manufacturer kit is available and it can rarely give false positive results. However, it is extremely sensitive esepecially at about 1 month after exposure because it detects viral DNA. All the other tests look for antibodies which depend on your body's immune response and may not turn positive for many months.
Nearly all labs that use the PCR also provide the Elisa antibody test as part of a combination package. Using both of these should result in accuracy of about 99% which is as good or better than any other type of testing.
I suspect most people who get the PCR have also received the Elisa.
