Rapid assays for Gaucher and Hurler diseases in dried blood spots using digital microfluidics.


ABSTRACT: Easy tool for newborn screening of Gaucher and Hurler diseases.Method comparison between fluorometric enzymatic activity assay on a digital microfluidic platform and micro-titer plate bench assay was performed on normal (n = 100), Gaucher (n = 10) and Hurler (n = 7) dried blood spot samples.Enzymatic activity analysis of glucocerebrosidase (Gaucher) and ?-l-iduronidase (Hurler) revealed similar discrimination between normal and affected samples on both platforms.Digital microfluidics is suitable for Gaucher and Hurler newborn screening.
