What is a haptoglobin (HP) test?
This test actions the quantity of haptoglobin in the blood. Haptoglobin is a protein produced by your liver. It attaches to a sure variety of hemoglobin. Hemoglobin is a protein in your red blood cells that carries oxygen from your lungs to the rest of your human body. Most hemoglobin is positioned inside of red blood cells, but little quantities flow into in the bloodstream. Haptoglobin binds to hemoglobin in the bloodstream. Alongside one another, the two proteins are identified as the haptoglobin-hemoglobin complicated. This complicated is promptly cleared from the bloodstream and taken out from the human body by your liver.
When red blood cells are damaged, they launch a lot more hemoglobin into the bloodstream. That implies a lot more of the haptoglobin-hemoglobin complicated will be cleared from the human body. The haptoglobin may possibly go away the human body more rapidly than the liver can make it. This brings about your haptoglobin blood amounts to fall. If your haptoglobin amounts are too low, it may possibly be a sign of a disorder of the red blood cells, these types of as anemia.
