Haptoglobin blood test

The haptoglobin blood test measures the level of haptoglobin in your blood.

Haptoglobin is a protein produced by the liver. It attaches to hemoglobin in the blood. Hemoglobin is a blood cell protein that carries oxygen.

Blood test

Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

Hemoglobin

Hemoglobin is the most important component of red blood cells. It is composed of a protein called heme, which binds oxygen. In the lungs, oxygen is exchanged for carbon dioxide. Abnormalities of an individual's hemoglobin value can indicate defects in the normal balance between red blood cell production and destruction. Both low and high values can indicate disease states.
