I went to MEPS months ago and I remember they said the blood and urine tests checked for drugs and std's. So do they check for just HIV? Or do they check for all the 4 "H"s (HIV, Herpes, and Hepatitis A&B)? Does the urine test check for bacterial stds? Medical conditions or general health? It'd be kind of nice to "know for sure" that my one and only boyfriend never gave me anything. He only had been with one other person but I'm a biology major and I'm familiar with the statistics so you never know. And I know you can test blood samples for tons of stuff so I wish they'd tell you all the interesting stuff about your blood while they're bothering to stick you.
