New Technique Uses Electrical Conductivity to Measure Blood in Dry Blood Spot Analysis

Science Newsline - Researchers from The University of Texas at Arlington have demonstrated that electrical conductivity can be an effective means to precisely measure the amount of blood present in dry blood spot analysis, providing a new alternative to the current preferred approach of measuring sodium levels.

Dasgupta and his co-author Jordan Berg, professor of mechanical engineering at Texas Tech University and co-director of the Nano Tech Center, published their findings, "Evaluation of the amount of blood in dry blood spots: ring-disk electrode conductometry," in Analytical Chemistry.
