The urinary excretion of D-glucaric acid and the plasma clearance of antipyrine were estimated during the acute phase of viral hepatitis and again during recovery. The plasma clearance of antipyrine was impaired during the acute stage of hepatitis, while the urinary excretion of D-glucaric acid was paradoxically high. Both parameters returned to normal during recovery. These findings suggest that the use of urinary D-glucaric acid excretion as an index of microsomal enzyme induction is unreliable when there is liver injury.
