First Claim
Patent Images
1. A system for detecting at least one analyte in a bodily fluid from a subject, the system comprising:
- a light source comprising a coating of luminescent paint and having an emission spectrum;
an assay assembly having one or more reactants to react with the bodily fluid to yield a colored product having an absorbance spectrum encompassing at least one wavelength within the emission spectrum from the light source; and
a detector that detects absorption of the at least one wavelength of light directed through the colored product, wherein said absorption of said at least one wavelength through the colored product is indicative of the presence of the analyte in said bodily fluid.
