Catecholamine metabolites vanillylmandelic acid (VMA), homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) are biomarkers for neuroblastoma and catecholamine secreting tumours. We present optimization of the method development process to maximize analyte sensitivity in the extraction and quantitation of these metabolites from plasma. Parameters investigated include MRM transitions, chromatography and sample preparation protocols.
