      (a) history or physical exam is suspicious for bleeding disorder or
      (b) for routine preoperative testing (PT, PTT, platelet count)

● See algorithms for prolonged PT, prolonged PTT, abnormal platelet count (platelet chapter) or hereditary bleeding disorder (PT, PTT, and platelet count normal)
