Abstract
A read-out method for a diagnostic point-of-care assay device, the device including a read-out substrate having at least one response area capable of producing a colored indication of a response, the response area including a marker at least one marker whose color changes in response to binding of an analyte thereto and which is used for indication of response. The method includes registering an image of the response area; calculating a color saturation value S for the image using at least two distinct wavelengths; using the S-value for determining a result of the assay. A read-out system (10) for an allergy point-of-care assay device is described. The system includes an illumination device (12; 21, 22) capable of delivering at least two different wavelengths of light; a color image capturing device (14); a control unit (19) for calculating a color saturation value on images recorded by the color image capturing device.
