There is interest in newborn screening of lysosomal storage diseases (LSDs) because of the availability of treatments. Pilot studies have used tandem mass spectrometry with flow injection of samples to achieve multiplex detection of enzyme products. We report a multiplexing method of 9 enzymatic assays that uses HPLC-tandem mass spectrometry (MS/MS).
