Haptoglobin Test, Serum


Test Description

The Haptoglobin, Serum test measures the amount of haptoglobin in the blood. Haptoglobin is a protein produced by the liver that binds to hemoglobin, a protein in red blood cells that carries oxygen from the lungs to the rest of the body.

When red blood cells are damaged, they release more hemoglobin into the bloodstream, which binds to haptoglobin. The haptoglobin-hemoglobin complex is then cleared from the bloodstream and removed from the body by the liver. This test is done to see how fast red blood cells are destroyed and to diagnose hemolytic anemia[1][2][3][4].

Indications of the Haptoglobin Test


A haptoglobin test is most often used to diagnose hemolytic anemia, a disorder that happens when red blood cells are destroyed faster than they are made. Symptoms of anemia include weakness, tiredness, pale skin, shortness of breath, jaundice, or a yellow tinge to the skin and the whites of the eyes, and dark-colored urine. This test may also be done if a patient has symptoms of liver disease[1][2][3][4].
