LD Isoenzyme 1; LD Isoenzyme 2; LD Isoenzyme 3; LD Isoenzyme 4; LD Isoenzyme 5; Lactate Dehydrogenase Total
The LD isoenzyme pattern is useful to evaluate the source of elevated LD activity. LD isoenzyme elevation associations: LD1: germ cell tumors; LD1>LD2: renal or myocardial infarction, megaloblastic anemia, hemolysis; LD3: platelet destruction, reactive, lymphadenopathy, lymphoma, lymphocytosis, pulmonary infarction, pneumonia, advanced cancer, acute pancreatitis; LD4, LD5: various solid tumors; LD5: primary liver disease, liver anoxia, muscle injury or dystrophy; All forms: renal disease, carcinomatosis, collagen vascular vascular disease, overwhelming sepsis, DIC
