Evaluation of the applicability of the SeHCAT test in the investigation of patients with diarrhoea

Scand J Gastroenterol. 1988 Jan;23(1):113-7. doi: 10.3109/00365528809093859.


For the assessment of ileal bile acid conservation the retention of orally administered 75Se-23-selena-25-homotaurocholic acid (SeHCAT), a gamma-ray-emitting radioisotope-labelled synthetic bile acid, was measured by an uncollimated abdominal gamma camera in 89 patients with various gastrointestinal disorders and in 20 persons without gastrointestinal complaints. A significant differences in retention was observed between patients with and without previously detected ileal disease. However, it was not possible by use of the test to differentiate between the various types of diarrhoea. Hence the test is not recommended in the routine investigation of patients with diarrhoea.
