Vi presenterar en bekväm fasta fasen extraktion kopplad till högtrycks vätskekromatografi (HPLC) med elektrokemisk detektion (ECD) för samtidig bestämning av tre Mao signalsubstanser och två av deras metaboliter i spädbarn urin. Vi identifierar också metaboliten MHPG som en potentiell biomarkör för tidig diagnos av hjärnskador för spädbarn.
