    摘要： Disclosed is a method for analyzing a blood sample. The method comprises arranging a cuvette comprising a sampling cavity and a sample analysis cavity on a rotatable member. The sampling cavity comprises a blood sample to be analyzed. The method comprises rotating the rotatable member at a first speed in a first rotation cycle for transfer of the blood sample from the sampling cavity to the sample analysis cavity. The method comprises rotating the rotatable member at a second speed in a second rotation cycle after the first rotation cycle for separating blood parts from plasma in the blood sample. The method comprises obtaining, using a photometer, during the second rotation cycle, second absorbance data indicative of absorbance in the plasma. The method comprises determining, based on the second absorbance data, a second blood parameter being a plasma free hemoglobin level of the blood sample. The method comprises providing an output indicative of the second blood parameter.

    摘要： Disclosed is cuvette for body fluid analysis. The cuvette comprising a sampling cavity comprising a fluid inlet, a sample analysis cavity, and a venting cavity being in fluid connection with the sampling cavity and the sample analysis cavity. The venting cavity has an outlet to the exterior of the cuvette. The cuvette is configured to transfer, when a centrifugal force is applied to the cuvette, a body fluid from the sampling cavity to the sample analysis cavity via the venting cavity. The sample analysis cavity is configured to provide a first capillary force, wherein the first capillary force is higher than a capillary force in the venting cavity. The sample analysis cavity is configured for separating and analyzing the body fluid sample.

    摘要： The invention relates to a sample acquiring device holder (3) for a housing (2) of an analysis apparatus (1). The sample acquiring device holder (3) may comprise an activating element (5) and a reception recess (11) for receiving a sample acquiring device (4). A first portion (10) of the activating element (5) may protrude into the reception recess (11), if the activating element (5) is in a non-activating position. The activating element (5) may be adapted to be moved into an activating position by the sample acquiring device (4), if the sample acquiring device (4) is inserted into an intended measurement position within the reception recess (11). The activating element (5) may be adapted to activate a measurement triggering element (15), if the activating element (5) is in its activating position, such that the measurement triggering element (15) activates a measurement of the analysis apparatus (1).
