Activities of bone and liver alkaline phosphatases in serum in health and disease.
A heat-inactivation method for determining absolute activities of liver and bone alkaline phosphatases in serum has been applied extensively in routine diagnosis. Values for each isoenzyme in healthy individuals of different ages are reported together with results obtained in various diseases. Data from normal subjects show that bone alkaline phosphatase contributes about half the total alkaline phosphatase activity in adults. Liver phosphatase shows a slight increase with age. The method is also able to detect reliably the presence of carcinoplacental isoenzymes.
