Abstract (en)
[origin: EP1916524A1] A disk-shaped, flat test element (1), rotatable about a (preferably central) axis perpendicular to the plane of the element, has a liquid sample introduction opening (4); a capillary-active region (12) (preferably a porous absorbent matrix) having a first end near and a second end spaced from the axis; and a sample channel (9) extending from near the axis to the first end of the capillary-active region. Independent claims are included for: (1) a variant of the test element, having a sample receiving opening with a sample dosing zone (5) contacting an excess sample zone (7), where a capillary stopper (6) is provided between the sample dosing and excess sample zones; (2) a method for determining an analyte in a liquid sample using the element, involving: applying the sample to the receiving opening; rotating the the element, so that the sample is transported to the first end of the capillary-active zone; slowing or stopping the rotation, so that the sample (or a material recovered from the sample on passage through the element) is sucked from the first end to the second end of the capillary-active zone; and visually or optically determining the analyte in the capillary-active zone or an adjacent zone; and (3) a system for determining an analyte in a liquid sample, comprising a test element as above and a measuring device including a drive for rotating the element and an optical system for evaluating the visual or optical signal from the element.
