Clinical Significance
Elevations in serum lactate dehydrogenase occur from myocardial infarction, liver disease, pernicious and megaloblastic anemia, pulmonary emboli, malignancies, and muscular dystrophy. Since lactic dehydrogenase is present in many body tissues, it’s diagnosis usefulness is limited. Tissue specificity may be enhanced by isoenzyme analysis.
