title: Simultaneous assay for urinary 4-hydroxy-3-methoxy-mandelic acid, 5-hydroxyindoleacetic acid and homovanillic acid by isocratic HPLC with electrochemical detection.
abstract: A method is described for the simultaneous determination of urinary HMMA, 5-HIAA and HVA by HPLC with electrochemical detection. The method was evaluated over an 8-month period and has thus far identified 2 cases of phaeochromocytoma, 1 case of neuroblastoma and 2 of carcinoid tumour.
