Abstract: An allergy testing system for use with a mobile electronic device having a camera includes a housing that can be attached to the mobile electronic device. First and second light sources within the housing are configured to illuminate, respectively, a test sample and a control sample. A colorimetric assay is performed on the test sample and the control sample. The first light source and the second light source are activated and the camera of the mobile electronic device captures images of transmitted light. The relative intensity of transmitted light is then used by software loaded on the mobile electronic device to determine a relative absorbance value. The relative absorbance value is used, together with a calibration curve, to measure the concentration of a particular allergen within the test sample. Based on the concentration of the allergen the test sample can be labeled as either “positive” or “negative.”
