Analysis of vanillylmandelic and homovanillic acids in urine using solid phase sample preparation and high pressure liquid chromatography with electrochemical detection.
A rapid, simple and specific method for quantification of vanillylmandelic acid (VMA) and homovanillic acid (HVA) in urine is described. The method is suitable for routine use and may include other organic acids in human urine.
