Diagnosing gout with Raman spectroscopy

Accurate diagnosis of medical conditions at point-of-care speeds treatment, improves patient outcomes and reduces healthcare costs. This application note shows how Raman spectroscopy is emerging as a tool to accurately diagnose gout and pseudogout for arthritis sufferers. Using a new compact point-of-care Raman spectroscopy (POCRS) instrument powered by a Wasatch Photonics integrated 785 nm Raman system, rapid objective testing of affected joints for painful crystals may be within reach for more clinics than ever before. The instrument has demonstrated comparable performance to a research-grade Raman microscope, and very good agreement with the existing gold standard diagnostic method in a clinical study.
