Haptoglobin
This test measures the amount of haptoglobin in your blood. Haptoglobin is a protein made by your liver to get rid of the hemoglobin outside your red blood cells.
A haptoglobin test is most often used to diagnose hemolytic anemia. Hemolytic anemia is a disorder that happens when your red blood cells are destroyed faster than they can be replaced. This test may also be used to see if another type of anemia or another blood disorder is causing your symptoms.

These labs do not agree: the published adult ranges differ by up to 2.8×, so the same result can read as normal at one lab and be flagged at another — ABIM 83–267 · ARUP 30–200 · Mayo 30–200 mg/dL. Both are real published values, shown as each lab states them.
