has essential measure obtained via diagnostic tool Blood Chemistry Measurement Serum Haptoglobin Level Measurement of the amount of haptoglobin in a specified sample of serum, the clear liquid that separates from blood after it has clotted completely, i.e. blood plasma from which fibrinogen has been removed. Haptoglobin is a serum alpha2 globulin glycoprotein, produced by the liver, that functions to bind free plasma hemoglobin, which allows degradative enzymes to gain access to the hemoglobin, while at the same time preventing loss of iron through the kidneys and protecting the kidneys from damage by hemoglobin.
