WebDecreased to absent levels occur more with intravascular than extravascular hemolysis: haptoglobin binds hemoglobin, and carries it to the reticuloendothelial system. Thus, haptoglobin is useful in work-up for hemolytic states. It is low in the megaloblastic anemias, which have a hemolytic component. It is decreased in infectious mononucleosis.

WebFeb 17, 2024 · Haptoglobin is an alpha-2 glycoprotein secreted mainly by the liver. It binds plasma free haemoglobin following red cell lysis, and as such the haptoglobin level will be reduced in the presence of haemolysis (particularly intravascular haemolysis). A reduced haptoglobin may also occur in the context of liver disease due to reduced production.
