Question

Can I still give blood if I took aspirin 15hours before my appointment to give blood?

Answer 1

yes you can. you cannot give platelets, however. A whole blood unit is fine.  

Answer 2

Yup. Aspirin's out of your system by now, though it takes a few days for the anticoagulant effect in the platelets to fade - they're basically replaced by your bone marrow.

So as above, whole blood is fine, but not platelets.
