Description:
Haptoglobin (HPT) Blood Test
This test measures levels of Haptoglobin in the blood. Haptoglobin is a protein produced in the liver. Its function is to bind to free hemoglobin in the blood and remove it. Most hemoglobin is found in red blood cells with a small amount being free or unbound. When red blood cells are damaged, they release hemoglobin into the bloodstream. The increase in free hemoglobin causes haptoglobin to be used up removing it, which causes a drop in haptoglobin levels. Therefore a decrease in haptoglobin levels can indicate that a person has a condition which is causing the damage or destruction of red blood cells. RBC destruction can be caused by a number of conditions and may lead to hemolytic anemia. Measuring haptoglobin levels can be useful when a person has symptoms of anemia such as fatigue, weakness, shortness of breath, or pale skin to help differentiate hemolytic anemia from other types. Since Haptoglobin is produced in the liver, low haptoglobin levels can also be the result of liver disease.
A Haptoglobin blood test is typically ordered when a person has symptoms of anemia. It is often ordered along with other lab tests such as a CBC, Reticulocyte Count, or Bilirubin.
Turnaround for this test is typically 1-3 business days.
