Abstract
An improved diagnostic method for detecting malabsorption comprising the oral ingestion by the patient of an effective amount of N-(2-aminoethyl)-glycine (Aeg), collecting the urine for eight hours post ingestion, then detecting the amount of N-(2-aminoethyl)-glycine in the urine by contacting the urine with an indicator substance which indicates the presence of N-(2-aminoethyl)-glycine. Suitable reagents include nihydrin, 2-methoxy-2,4-diphenyl-3-(2H)-furanone, o-phthalaldehyde and fluorescamine, with fluorescamine being preferred. The determination can be made quantitative by treating the urine with a source of active chlorine or bromine prior to contact with the indicator.
