It is a protein produced by liver to clear free hemoglobin (iron transporting protein) from circulation (which is outside the erythrocytes). Haptoglobin binds to free hemoglobin in blood, forming a complex that is rapidly cleared out from circulation by the liver, so that iron will not be lost and recycled in the body.This large complex also prevents the hemoglobin to be filtered by the kidneys to prevent excretion in urine and protect the kidneys from the toxic effects of this molecule.
Interpretation: When large amounts of hemoglobin is destroyed for any pathological condution, haptoglobin levels will temporarily decrease the free hemoglobin in the blood in circulation rises and and causes tissue and organ damage due to oxidative stress caused by the free hemoglobin
