¹³C-methacetin and¹³C-galactose breath tests can assess restricted liver function even in early stages of primary biliary cirrhosis

Abstract

In non-cirrhotic, early-stage, primary biliary cirrhosis the 13C-methacetin breath test and the 13C-galactose breath test reliably indicate decreased liver function. The 13C-galactose breath test can also predict the histological score.
