The determination of haptoglobins in normal human serum

Abstract
The peroxidase activities of methaemoglobin and of methaemoglobin-haptoglobin complex on the reaction between guaiacol and hydrogen peroxide have been examined and a method for the determination of haptoglobins in serum was devised. The method has been used to determine the serum haptoglobin concentration in normal human serum. A mean value (as bound methaemglobin) of 93 mg/100 ml (S.D. 40) was obtained. The mean serum-haptoglobin concentration varied according to the genetic haptoglobin type.
