摘要：A method of measuring at least one of a catecholamine and its metabolite including a biological sample pretreatment process, a fluorescence inducing process of converting into a fluorescence inductor the at least one of a catecholamine and its metabolite in the biological sample subjected to pretreatment by means of a fluorescence inducing reagent, and a measuring process of separating and measuring said fluorescence inductor by liquid chromatography, said method being characterized by addition of a specified volume of maleimide before said process of making the biological sample fluorescent.
