The system for the examination of liquid samples, especially to determine blood glucose levels, has a number of test elements (14) preferably in a test strip (12) stored in a cassette. The test elements are moved in succession to a delivery point, by a strip advance mechanism, to be soaked by the blood sample and be moved on to the analysis point for scanning by a measurement unit. The scanning station is at a gap from the test element saturation point. The wet test element is moved into place by the transport mechanism and accurately positioned by a positioning unit which stops the movement when the test element is in place for scanning.
