What is a haptoglobin (HP) check?

This check actions the quantity of haptoglobin in the blood. Haptoglobin is a protein designed by your liver. It attaches to a specified variety of hemoglobin. Hemoglobin is a protein in your red blood cells that carries oxygen from your lungs to the rest of your system. Most hemoglobin is found inside of red blood cells, but tiny amounts flow into in the bloodstream. Haptoglobin binds to hemoglobin in the bloodstream. With each other, the two proteins are acknowledged as the haptoglobin-hemoglobin complicated. This complicated is quickly cleared from the bloodstream and removed from the system by your liver.

When red blood cells are weakened, they release far more hemoglobin into the bloodstream. That indicates far more of the haptoglobin-hemoglobin complicated will be cleared from the system. The haptoglobin may go away the system more quickly than the liver can make it. This results in your haptoglobin blood levels to drop. If your haptoglobin levels are much too minimal, it may be a indication of a dysfunction of the red blood cells, this sort of as anemia.
