Study Overview
Brief Summary
This study aims to validate a possible diagnostic test for bile acid diarrhoea prospectively compared to the SeHCAT scintigraphy. Fasting participants are given a standard meal and 1,250 mg chenodeoxycholic acid. The investigators measure fasting FGF19, bile acids species including 7-alpha-CHO and serial blood samples after the stimulation.

- Correlation of FGF19 to clinical diarrhoea(Individual data are collected within one week)
- 7alpha-CHO by SeHCAT stratum(Individual data are collected within one week)
- Other diagnostic and Nosographic propabilities stimulated deltaFGF19, SeHCAT < 5%(Individual data are collected within one week)
- Diagnostic and Nosographic propabilities of 7alpha-CHO for SeHCAT <10%(Individual data are collected within one week)
- FGF19 by SeHCAT stratum(Individual data are collected within one week)
- Correlation of 7alpha-CHO to clinical diarrhoea(Individual data are collected within one week)
