Davie/Bute
The std clinic at Davie/Bute is a walk-in. I've never had to wait more than a few minutes. I think the same people work there as the one on 12th and I also beleive their computer records are linked so going to either is basically same.
Same annon system...you only give your name/show ID if you want a print out of the results.
(Otherwise the Health nurse/section might have the number for the one on 12th)
