A 51-year-old woman sees her physician because of abdominal cramping and diarrhea. Large amounts of blood are present in her stools. She has a past history of a peptic ulcer and hypertension. The surgeon who is also evaluating her is concerned about the amount of blood in the stool and has asked the referring physician to rule out a coagulopathy.
