Faecal P.V.P. Excretion in Hypoalbuminaemia and Gastro-intestinal Disease

Abstract

MEDICAL JOURNAL~~~~~~~~~~ n 67 instances the results of the tubeless test were compared with the findings after augmented histamine stimulation. Only two false-positive results were detected, and these were explained by errors in tech- nique. Fewer false-negative results occurred with betazole hydrochloride than when caffeine benzoate was used as the stimulant.
