I had unprotected sexual intercourse and slept in the same bed with a girl who had as many as 20 partners. This happened about a month ago. She claims she was tested and everything.. now I have tiny bumps in random places around my body. They are very small, and are barely visible. Arms, Legs, Stomach, Chest, one on my scrotum. They are extremely itchy, and sometimes appear as tiny red dots. There aren't many on me. I would guess maybe 15 on my entire body... and of which only 4 or so are still itchy.

Does this sound like scabies? While we were together, her skin was VERY smooth and VERY clear, it was actually some of the best skin I've ever come across.. so it didn't seem like she had them at all.

Also, would a blood/urine test reveal scabies, or can they only be diagnosed visually by a doctor?
