摘要: During an assay, optical measurements are made at a sensing surface (112), and at least one “homogeneity-image” of the sensing surface (112) is generated. From this image, an “homogeneity-indicator” is determined for at least one region of interest, and the optical measurements are then evaluated in dependence on said indicator. The homogeneity-indicator may for example be a binary value which indicates if an inhomogeneity was detected or not. If an inhomogeneity was detected, all optical measurements may be rejected, only measurements for the involved region of interest may be rejected, or measurements for a selected sub-area of the involved region of interest (ROI) may be rejected.

摘要: A substance determining apparatus determines a substance within a fluid where particles, which have attached the substance, are bound to a binding surface. A sensing unit is configured to generate a sensing signal being indicative of at least one of i) a distance between the particles bound on the binding surface and the binding surface, and ii) an in-plane position of the particles bound on the binding surface. A binding discrimination unit is configured to discriminate between different kinds of binding of the particles bound on the binding surface depending on the generated sensing signal. The binding discrimination unit may be a unit for determining the part of the sensing signal being caused by specifically bound particles and for determining the substance based on this determined part of the sensing signal.

摘要: The invention relates to a substance determining apparatus for determining a substance within a fluid. Particles attach the substance and bind to a binding surface (30), wherein a sensing signal is generated depending on the bound particles. Binding events indicating a binding of a particle on the binding surface (30) are determined from the generated sensing signal, and the substance within the fluid is determined based on the determined binding events. During a procedure of determining a substance within a fluid, particles may bind to the binding surface and may leave the binding surface. Therefore, during this procedure a number of binding events can be determined being much larger than the number of bound particles. The determination of the substance within the fluid can therefore be based on a very large amount of data, thereby increasing the accuracy of determining the substance within the fluid.
