Apresentamos uma conveniente extração de fase sólida acoplada a cromatografia líquida de alta pressão (HPLC) com deteção eletroquímica (ECD) para a determinação simultânea de três neurotransmissores monoamina e dois dos seus metabolitos na urina dos bebês. Também identificamos o metabólito MHPG como um potencial biomarcador para o diagnóstico precoce de lesões cerebrais para infantes.
