Interstitial fluid could be a new source for biomarkers

Researchers from the Georgia Institute of Technology (GA, USA) and Emory University (GA, USA) have developed a new technique for obtaining biomarkers. The minimally invasive technique is used to extract dermal interstitial fluid (ISF) that could be used to provide a new source of information for monitoring and diagnostic testing. The results of the human trial are available to read in Science Translational Medicine. The through-the-skin technique could allow for continuous monitoring of glucose and other key health indicators, as dermal ISF does not clot. "Interstitial fluid originates in the blood and then leaks out of capillaries to bring nutrients...
