Schematic showing the various assays used for the diagnosis of HIT. In this report, we propose the use of surface-enhanced Raman spectroscopy inside a capillary tube (“SERS-in-a-capillary”) to significantly reduce the turn-around time for HIT diagnosis compared to existing approaches such as immunoassays and serotonin release assay.
