Interferometric Detection and Quantification System and Methods of Use in Healthcare

A portable interferometric system for detection and quantification of analyte within a healthcare test sample composition, the system comprising:

• an optical assembly unit, the optical assembly unit comprising a light unit and a detector unit each adapted to fit within a portable housing unit;
• and
• a cartridge system adapted to be inserted in the housing and removed after one or more uses, the cartridge system comprising an interferometric chip and a flow cell wafer.
• wherein the interferometric chip includes one or more waveguide channels having a sensing layer thereon, the sensing layer adapted to bind or otherwise be selectively disturbed by one or more analytes within the animal health test sample composition.
