Haptoglobins

Haptoglobin is a protein which is found in the blood of humans and other mammals. It binds free hemoglobin released from red blood cells, preventing it from being removed from the circulation by the kidneys. This process helps to protect the body from further hemolysis (breakdown of red blood cells). Due to its ability to bind hemoglobin, haptoglobin is an important factor in diagnosing anemia and other hemolytic disorders. Haptoglobin levels are routinely tested to diagnose these disorders and to identify the underlying cause. Additionally, some research suggests haptoglobin may have antioxidant and anti-inflammatory properties, demonstrating potential roles in the development of autoimmune and cardiovascular diseases.
