How does the OptiScanner measure glucose?

Unlike enzymatic-based systems that measure glucose from whole blood and use a standard calculation to convert to a plasma equivalent, the OptiScanner 5000 Glucose Monitoring System measures glucose directly from a plasma sample. The OptiScanner has an integrated spectrometer that uses mid-infrared wavelength light to detect glucose in blood plasma. Glucose concentration in a centrifuged sample of whole blood is then calculated using an algorithm that accounts for multiple interferents.
