Serum Complement in Hepatobiliary Diseases.

Abstract
In 20 patients with acute hepatitis, 20 with hepatic cirrhosis, and 25 with (benign and malignant) biliary obstruction, the serum complement titer was distinctly subnormal in only 2 moribund patients suffering from cirrhosis. The data speak against formation of complement in or through the liver and fail to indicate usefulness of complement titration in diagnosis of hepatobiliary diseases.
