Urinary catecholamines: comparison between HPLC with electrochemical detection and fluorophotometric assay.
Comparisons between catecholamines determined by HPLC (with electrochemical detection) and fluorometry in urine samples from healthy adults and children, respectively, showed high correlations. In agreement with greater specificity for HPLC, mean values were higher for the fluorometric assay. However, it was concluded that fluorometric assays provide as valid and sensitive indices of stress-induced changes in catecholamine excretion in humans as HPLC.
