LDH (Lactate Dehydrogenase)
LDH is an enzyme present in nearly all cells that catalyzes pyruvate to lactate during anaerobic metabolism and is released when cells are damaged. Elevated serum LDH is nonspecific and occurs with hemolysis, liver disease, heart attack, kidney injury, lymphoma, and many cancers. It is used to gauge disease activity and treatment response rather than for diagnosis.
