Claiming that test results mean "nothing" after someone has contact with someone else is just plain statistically inaccurate. The significance of the test results does degrade over time. However, the chance of someone who has a 6 month old test result showing up HIV+ in 6 months is still less than someone who is untested.

Porn film actors get tested ever 30 days for HIV, Chlamydia and Gonorrhea-and do a set of more extensive tests every 6 month. Chlamydia and Gonorrhea spread really fast. HIV doesn't spread fast-but obviously the consequences are more severe(the tests used by porn actors are also more sensitive than those that are used by the general public and show HIV+ status a few days after infection). More importantly, the entire population of Porn actors gets tested and much of the sexual activity of porn actors is with each other(or a stable partner who is also only active in that particular population).

The AIM Foundation protocol for testing porn actors isn't perfect. However, it does appear to be working a lot more effectively than a lot of detractors would have predicted.

I'd be very careful of using the limitation of testing as a reason to encourage folks not to test or request test results from partners.
