Use of unabsorbed radioactive marker substances in a re-assessment of the radioactive triolein test of fat absorption

摘要

The radioactive triolein test has been compared with two chemical methods for the assessment of fat absorption in a group of inpatients from general medical wards. The special feature of the investigation is the use of a radioactive faecal marker to measure the completeness of faecal collections during the investigation period. Estimations of unabsorbed 131I triolein and faecal fat measured by the chemical methods were made on the same specimens.
