The FoodID Antibiotic Residue Test consists of eight (8) immunoassays in a lateral flow format. Each assay utilizes visual labels attached to monoclonal detection antibodies in a competitive format to quantify the amount of target analyte present in a test specimen. The visual signal created by the assay is detected by a camera-based reader platform which compares the detected signal against a lot-specific factory calibration to produce a result. This method allows for the quantitative measurement of an analyte in a given specimen.
