title: Survey of serum enzyme analyses. Human tissues as a source of enzymes.
abstract: The College of American Pathologists' enzyme survey permits the evaluation of the quality of enzyme analyses in clinical laboratories. Animal source enzymes for lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, and creatine kinase are satisfactory as supplements for enzyme survey serum, since they give results equivalent to human source enzymes. This finding makes the interconversion of results by different methods possible, and the estimation of the upper limit of normal based on the results obtained for the enzyme survey serum.
