Handheld Spectral Analyzer for Point-of-Care Diagnostics

A spectral transmission-reflectance-intensity (TRI) analyzer was developed that attaches to a smartphone and analyzes patient blood, urine, or saliva samples as reliably as clinic-based instruments. It is capable of performing thousands of current tests that may be adapted to the device, including an enzyme-linked immunosorbent assay (ELISA) that detects and measures a wide variety of proteins and antibodies in blood, and is commonly used for a wide range of health diagnostics tests. The system is capable of detecting the output of any test that uses a liquid that changes color, or a liquid that generates light output (such as from fluorescent dyes).
