Evaluation of the diagnostic value of serum bile acid in the detection and functional assessment of liver diseases.

abstract：:Simultaneous localisation of the isoenzymes of alkaline phosphatase and gamma-glutamyl transferase was carried out on 173 serum samples from patients with hepatobiliary and bone disease to determine (i) if a better discrimination of the underlying pathology could be obtained by such an approach, and (ii) if the pathol...
