Abstract: The present disclosure relates to devices, apparatus and methods of improving the accuracy of an image-based assay. One aspect of the present invention is to sandwich a sample between two plates and add reference marks in the sample areas of the plates, with at least one of the geometric and/optical properties of the reference marks being predetermined and known, and taking images of the sample with the reference marks, and applying a machine learning model in the analysis of the image-based assay.

Abstract: A homogeneous assay method that employs a device is provided. In some embodiments, the device contains a pair of plates that can be opened and closed. The sample is placed between two plates. In some embodiments, the thickness of the sample in a closed configuration, the concentration of labels, and amplification factor of the amplification surface are configured to make the label(s) bound on the amplification surface visible without washing away of the unbound labels.
