Hemolytic anemia, a condition where the body destroys red blood cells prematurely. Sickle cell anemia, an inherited disorder characterized by abnormal, crescent-shaped red blood cells.
Thalassemia, an inherited disorder where an abnormal form of hemoglobin destroys red blood cells prematurely. These tests may include: A reticulocyte count to see if your bone marrow is making red blood cells at an accelerated rate this is a sign of prior blood loss Serum iron and ferritin tests to check the amount of iron in your blood and body A peripheral blood smear to see if your red blood cells are an abnormal shape Hemoglobin electrophoresis to evaluate for abnormal hemoglobin, which is present in thalassemia and sickle cell disease An osmotic fragility test to see if your red blood cells are more fragile than usual Your doctor may use more tests to search for the cause of your anemia.
