FALSE a test just say that you were ok for HIV 3 months before the test as, as stated before, it takes up to 3 months for antibodies against HIV to be detectable. For other common STD, the negative results just testify that you were ok the day the samples were taken. So much safer doesn't mean a lot, specially if one had unprotected sex between the day of sampling and the one of the results. So, TRUE, being tested regularly is better than no test or once a year but is in no way a warranty of anything. Much better? I don't think so. I don't want to start a fight with anybody here, just let us be realistic and objective.
That is why (regarding HIV) doctors recommend to new stable couples to play safe for 3 months, than get tested and continue to play safe until the results are known an hopefully negative. After it is a question of trust.
I'm not saying it's a warranty of anything! Being sexually active is a risk in itself, so the best we can do is get tested regularly that's all I was saying
