An assay to determine anticoagulants in a blood or blood plasma sample, wherein the assay comprises analyses with at least two wet chemistry prothrombine time (PT) methods. The assay comprises measuring PT in a first reaction mixture with a first PT method and measuring PT in a second reaction mixture with a second PT method, wherein the concentration of blood or blood plasma in the second reaction mixture differs from the concentration of blood or blood plasma in the first reaction mixture. The PT methods are calibrated to give the same or approximately the same PT results for reference samples which lack anticoagulants of interest for the assay. Further, calculating a difference in PT from the measurements, wherein if the difference in PT is 1) significant, this is indicative of a presence of anticoagulants in the sample, or 2) non-significant, this is indicative of an absence of anti-coagulants above detectable level in the sample.

A surface plasmon apparatus includes a light source, a sensor unit for Surface Plasmon Resonance (SPR) which includes a transparent sensor structure forming at least one wall of a cavity, the wall being defined by a concave inner surface and a convex outer surface, wherein the inner surface is provided with a layer of a conductive material capable of supporting a surface plasmon, a flow structure in the cavity so as to form at least one compartment for sample between the flow structure and the inner wall of the cavity, a detector for detecting reflected light from the sensor unit, and a processing unit.

Surface plasmon apparatus

The invention relates to a sensor unit for a Surface Plasmon Resonance (SPR) unit, comprising a transparent sensor structure forming at least one wall of a cavity, the wall being defined by a concave inner surface and a convex outer surface The inner surface is provided with a layer of a conductive material capable of supporting a surface plasmon. In the cavity there is provided a flow structure in said cavity so as to form at least one compartment for sample between the flow structure and the inner wall of the cavity. Also, a method for the detection of events at a surface by utilizing surface plasmon resonance is provided. It comprises placing a sample with an analyte of interest in a sensor unit as claimed in claim, and measuring the reflectance from said sensor unit at a single or plurality of angle/angles.
