Clinical Significance
Lactate is the end product of the anaerobic metabolism of glucose. The concentration of lactate in the blood is dependent on the rate of production in muscle cells and erythrocytes and the rate of metabolism in the liver. Lactic acidosis usually results from overproduction or underutilization of lactate. Elevated lactate levels can occur as a result of tissue hypoxia; diabetes mellitus; phenformin therapy; malignancies; glycogen storage disease; ethanol, methanol, or salicylate ingestion; and metabolic acidosis.
