It's not a validated test yet I don't think. Re-testing is being done. Girls should refuse to work with gay performers and those who date gays IMO. ....I know that reduces the fuck pool drastically.
In the medical industry it IS a validated test, it's not like it's a take home test. Because it's no different than the second PCR-DNA test and the next (except it's a few days or so recent.) But in these cases multiple re-tests with various methods are done to confirm the original test is yay or nay. It's a little bit of the fact that medical testing isn't 100% and a little bit of denial.
I really loathe how the jizz biz words things.
