Definition


Haptoglobin is a protein found in the blood that increases in quantity when reacting to inflammation in the body. Normal levels are of between 0.5 and 2.5g/l, reached by the age of 2. Increased haptoglobin blood levels indicate an inflammatory syndrome caused by arthritic flare-up, infectious disease, acute nephropathy, or even a type of cancer. In contrast, reduced levels can be caused by hemolysis, even one of limited severity, hepatitis, or, again, nephropathy.
