What effect does aspirin have on bleeding time?

Show Answers

Prolongs bleeding timeExtends clotting timeRaises partial thromboplastin timeIncreases activated partial thromboplastin timeNo effect on coagulation parameters

Explanation

Aspirin primarily inhibits platelet function, which leads to a prolonged bleeding time (BT). It does not significantly affect clotting time (CT), partial thromboplastin time (PTT), or activated partial thromboplastin time (APTT).
