Medical term:
haptoglobin
haptoglobin
[hap´to-glo″bin]a group of serum alpha2-globulin glycoproteins that bind free hemoglobin; three phenotypes, with differing abilities to bind hemoglobin, are distinguished electrophoretically.

hap·to·glo·bin (HP),
(hap'tō-glō'bin), [MIM*140100 & MIM*140210]A group of α2-globulins in human serum, so called because of their ability to combine with hemoglobin, preventing loss in the urine; variant types form a polymorphic system, with α- and β-polypeptide chains controlled by separate genetic loci. Levels are decreased in hemolytic disorders and increased in inflammatory conditions or with tissue damage.
[G. haptō, to grasp, + hemoglobin]

haptoglobin
(hăp′tə-glō′bĭn)n.
A plasma protein that is a normal constituent of blood serum and functions in the binding of free hemoglobin in the bloodstream.

haptoglobin
A protein in the circulation that migrates in the α2 portion of serum subjected to electrophoresis, a so-called acute phase reactant that ↑ in serum in acute inflammation or infection, stress, or necrosis Role Bind Hb released from RBCs undergoing hemolysis, preventing the accumulation of Hb in plasma; after iron has been removed, the haptoglobin-bound Hb is eliminated by the reticuloendothelial system.McGraw-Hill Concise Dictionary of Modern Medicine. © 2002 by The McGraw-Hill Companies, Inc.

haptoglobin
Alpha2 -globulin, a plasma protein that binds free haemoglobin to form a complex too large to pass out of the kidneys into the urine.Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005
Haptoglobin
A blood protein made by the liver. Its main role is to save iron by attaching itself to any hemoglobin released from a red cell.
