Serum binding globulin

Haptoglobin, also called haptoglobin, is a & alpha; 2 globulin synthesized by the liver, accounting for about 1% of total plasma protein, and can bind to hemoglobin in Xuejiang to form a certain complex. When hemolysis occurs, the free hemoglobin in the plasma increases, the globin bound to it increases, and the plasma haptoglobin decreases, which is a very sensitive indicator of intravascular hemolysis.
