US 2009/0154776 A1 · Optical Imaging Clinical Sampler

Abstract

A clinical sampling system including a reader capable of optically imaging a test cartridge presented thereto and then automatically determining the presence and concentration of a target compound in a liquid sample placed on the test cartridge. The reader includes an optical imaging unit for illuminating, imaging, and interpreting the test cartridge. The test cartridge houses a reaction strip having a control region and a sample region that reacts to a liquid sample placed on the strip. The presence and concentration of the target compound are interpreted by determining the relative reflected intensities of the control region and sample region and calculating the ratio of the reflected intensities relative to the reflected intensity of the background.
