Near-Infrared Spectroscopic Instrument for Non-Invasive Clinical Chemistry

Introduction The analysis of biological samples is essential during patient care. Many such samples are traditionally measured using lengthy and complicated procedures which require the preconditioning of a blood sample withdrawn from the body. Preconditioning can be a lengthy and expensive process and usually destroys the sample. Near-infrared (NIR) spectroscopy can be used to non-destructively analyze biological samples that contain water. Due to light scattering and difficulties in choosing specific NIR wavelengths, NIR spectroscopy of biological samples has not been a straightforward process. Technology description The present invention, discovered by researchers at the University of Washington, provides a method for using NIR spectral instrumentation to rapidly, inexpensively, and accurately characterize the properties of water-containing biological matter. Additionally the properties of the sample are predicted without any preconditioning, such as chemical alteration or physical separation. Business opportunity There is a high demand and large market for non-invasive biological sample monitoring. Stage of development NIR instrumentation that uses this method has been developed to detect hematocrit and hemoglobin levels in blood and other applications are under development.
