Analysis of Circulating miRNA from Dried Blood Spots

Circulating microRNA (miRNA) molecules have been implicated in many disease states including cancer, diabetes and cardiovascular disease. In this study, the authors demonstrate for the first time that circulating miRNA levels can be accurately measured from dried blood spot (DBS) samples. To collect DBS samples, a novel collection device was used (HemaSpot), that simplifies self collection from any location and at any time.
