Reference Values
40 – 240 mg/dL
Interpretation
Decreased levels of haptoglobin are seen in response to hemolysis. Transfusions which contain a small fraction of hemolyzed red blood cells can lower the level. Increased levels occur with acute or chronic inflammatory response, tissue destruction, and malignant neoplasms.
