  Yes, but assuming the nurse/phlebotomist uses an alcohol wipe, that's a non-issue (or, no more an issue than back of hand or inside of elbow). But, with a typical blood draw, you have a larger puncture, with a relatively lengthy and deep penetration by needle (vs a prick which is smaller, less deep, and quickly in/out).
