Summary
The fasting levels of chenodeoxycholic and cholic acid conjugates in various groups of patients [25 healthy subjects, 20 patients with chronic active liver disease (CALD), 21 patients with primary biliary cirrhosis (PBC) and 5 patients with cholesterol gallstones before and after chenodeoxycholic acid therapy] were determined by using a sensitive, accurate and precise radioimmunoassay. The results obtained with this method were compared with those of a gas-chromatographic method with methylation and acetylation of the bile acids using a 2 m × 0.4 cm glass column packed with 3% of AN 600 on Anakrom Q 110–120 mesh. The results obtained with both methods are in agreement; therefore the method used can be applied for quantitative analysis. In diagnosis, the measurement of serum bile acid levels, fasting or after meals, proved to be a very sensitive method, although further correlations are necessary with standard liver function tests.
