Abstract
The present invention relates to a device and a method for detecting substances which are present in biological or chemical samples, each substance producing an optically detectable signal upon reaction with a reagent. The device further comprises a sample carrier with at least two receptacles for receiving samples and is characterized in that at least part of the receptacle is equipped to receive at least 2 reagents each, and in that a camera for recording an image which shows at least one receptacle filled with at least two reagents for the detection of different substances, and an evaluation device for evaluating the samples which device is designed such as to evaluate each image by analyzing the signals in the image. Said method comprises the following steps: Introducing at least two reagents into one receptacle of a sample carrier, and optionally immobilizing the reagents, adding the sample to the receptacle, recording an image by means of a camera such that the image shows the receptacle which is loaded with at least two reagents, and evaluating the image by analyzing the color spectrum of the samples in the image.
