Thanks for the info guys!
You can test for most std's after a week. You'll need to wait a full 3 months for hiv and hsv testing.
Not sure if you are male or female but there isn't a commerically available test for hpv for males and they don't test for external genital warts in females.
www.ashastd.org has a full list of std's and how to test for them and when.
