6. How Are Low Hemoglobin Levels Diagnosed?
A health care provider reviews a person's medical history and asks about their symptoms. They draw blood that undergoes laboratory testing to determine the amounts of hemoglobin and iron in the blood.
Under some circumstances, they may conduct a bone marrow aspiration or biopsy to check the size, number and maturity of blood cells and to detect any abnormal cells. To check for bleeding in the gastrointestinal tract, the provider may order an endoscopy.9‘Iron-Deficiency Anemia.’ Johns Hopkins Medicine, www.hopkinsmedicine.org/health/conditions-and-diseases/irondeficiency-anemia.
