Strong chromatographic effects were observed for target analytes during dried urine spot (DUS) collection, which had a crucial impact on their distribution within the DUSs and demonstrated that sub-punching, often applied to dried material spots, is not acceptable for quantitative DUS analyses. Hence, a simple, rapid, and user-friendly procedure was suggested, which employed an in-vial collection of a known urine volume on a pre-punched sampling disc and in-vial processing of the whole DUS.
