Answer

Occasionally, patients with severe iron deficiency anemia from slow but persistent gastrointestinal (GI) bleeding have repeatedly negative testing of stool for hemoglobin. Therefore, it is important for the clinician to be aware of characteristics of the anemia at all intervals after the onset of bleeding.

Go to Anemia, Sideroblastic Anemias, and Chronic Anemia for complete information on these topics.
