Concept explainers
(a)
Interpretation: The medical diagnostic value associated with the enzyme, LDH in the bloodstream has to be predicted.
Concept introduction: The concentration of enzymes is useful for obtaining information about a heart attack. The blood levels of the three enzymes commonly assayed in heart attack situation are: creatine phosphokinase (CPK), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH).
(b)
Interpretation: The medical diagnostic value associated with the enzyme, AST in the bloodstream has to be predicted.
