OPTICAL INDICATOR FOR DETECTING BACTERIAL PATHOGENS

摘要

A clinical testing assay device that can differentiate bacterial from viral infections is described. The assay device has a sample contact zone with an absorbent pad on which a test sample is deposited and a detection zone with a colorant indicator that is sensitive to bacteria cells. The colorant indicator changes color when exposed to a bacteria sample. The color change signal can manifest relatively quickly, usually within a few minutes, and with an intensity correlative to the concentration of bacteria in a test sample. A method of use is also provided.
