Capillary electrophoresis (CE) has been investigated for the analysis of some neurotransmitters, dopamine (DA), 3-methoxytyramine (3-MT) and serotonin (5-hydroxytryptamine, 5-HT) at nanomolar concentrations in urine. Field-amplified sample injection (FASI) has been used to improve the sensitivity through the online pre-concentration

A substantial number of patients with head and neck paragangliomas (HNPGLs) have biochemically active tumors, evidenced by increased urinary excretion of catecholamines and metabolites, including 3-methoxytyramine (3MT). It is unclear whether plasma levels of these parameters are more sensitive to

Patients with head-and-neck paragangliomas (HNPGL) are regularly screened for catecholamine excess. The clinical relevance of increased urinary secretion of 3-methoxytyramine is unclear in HNPGL. The aim of the study was to assess the prevalence and the clinical, biochemical, and radiological
