Description
Many different types of body cells contain the enzyme lactate dehydrogenase, particularly those in the heart, kidney, liver, and muscle. LDH levels may be abnormally high in heart attack and liver disease, as well as other diseases. LDH catalyzes the conversion of lactate to pyruvate, an important step in energy production in cells. LDH levels are used for assessment of myocardial infarction, liver disease, pernicious and megaloblastic anemia, pulmonary embolus, malignancy, and muscular dystrophy
