title: Other enzymes. Creatinine phosphokinase, lactate dehydrogenase, serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, and alkaline phosphatase.
abstract: Enzyme assays remain an important laboratory tool for the Emergency physician. This chapter has reviewed the biochemistry of the enzymes routinely assayed and the pathophysiology of the organs that liberate those enzymes with respect to particular disease states. Information on costs and turnaround time is listed in Table 8. The most important tool that a clinician has available is clinical judgment. A laboratory test should confirm a diagnosis already entertained, not make one by surprise.
