Abstract:
The absorption of vitamin B12 in selected pathological states of the gastrointestinal tract was studied. Schilling test was performed with 37 kBq (1 microCi) of 57Co-labelled vitamin B12 as an analysis of urinary radioactivity. No increase in cobalamin absorption was present after exogenous IF had been administrated to patients after resection of the upper part the stomach and total gastrectomy. This suggests that there is another factor likely to affect vitamin B12 absorption.
