    • 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.
    • 一种用于检测吸收不良的改进的诊断方法,包括患者口服摄入有效量的N-(2-氨基乙基) - 甘氨酸(Aeg),摄入后8小时收集尿液,然后检测N-(2- - 氨基乙基) - 甘氨酸通过使尿液与表示N-(2-氨基乙基) - 甘氨酸存在的指示剂物质接触。 合适的试剂包括游离醇,2-甲氧基-2,4-二苯基-3-(2H) - 呋喃酮,邻邻苯二甲醛和荧光胺,优选使用荧光胺。 可以在与指示剂接触之前用活性氯或溴源处理尿液来定量测定。
