Question

You get a page from a gastroenterologist asking for a consult for platelet transfusion prior to an elective colonoscopy scheduled for tomorrow. The patient is a 56yo male, with a history of ITP and HTN. This procedure is for screening purposes only and the patient has not had any melena, hematochezia, or rectal bleeding. Platelet count is 97 x 10⁹ per liter and the rest of the CBC is within normal limits.

1. Does this patient meet the platelet transfusion threshold?
   1. If so, how much would you transfuse?
2. If you were worried about bleeding, what are the other tests you could order to assess platelet function?
