We herein report the simultaneous determination of the levels of noradrenaline (NA), and 3-methoxy-4-hydroxyphenylglycol (MHPG), a major metabolite of NA. The sample was subjected to a Sep Pak C18 cartridge prior to the NA and MHPG assay by high-performance liquid chromatography with an electrochemi
