Clinical Significance

Haptoglobin binds hemoglobin, which is released during erythrocyte lysis. The haptoglobin/hemoglobin complex is rapidly eliminated from the blood stream. Increased release of hemoglobin due to intravascular hemoloysis results in a reduction in the haptoglobin concentrations, during severe hemolysis, to complete consumption of the haptoglobin. In children, haptoglobin has lower physiological serum concentrations and, therefore, is not suited for hemolysis testing. Haptoglobin is an acute-phase protein, which can develop very high serum levels during inflammatory conditions.
