Patent ID: 7833479

Claim:
A cuvette for taking up a body fluid sample and for providing the body fluid sample to an analysis, said cuvette comprising: an inlet cavity for receiving a body fluid sample to be analyzed, a centrifugation reception cavity, which is arranged in communication with the inlet cavity such that spontaneous flow from the inlet cavity to the centrifugation reception cavity is prevented and such that body fluid from the inlet cavity may be forced into the centrifugation reception cavity by applying a centrifugation force on the cuvette, an analysis sample reception cavity, which is arranged in capillary connection with at least part of the centrifugation reception cavity for providing a sample transport by capillary action from the centrifugation reception cavity to the analysis sample reception cavity, a measurement cavity, which is arranged in communication with the analysis sample reception cavity such that body fluid from the analysis sample reception cavity may be forced into the measurement cavity by applying a centrifugation force on the cuvette, wherein the inlet cavity, the centrifugation reception cavity, the analysis sample reception cavity and the measurement cavity have openings through an outer wall of the cuvette, said openings extending over the entire width of the cavities, respectively.
