Abstract

A test element and method for detecting an analyte with the aid thereof is provided. The test element is essentially disk-shaped and flat, and can be rotated about a preferably central axis which is perpendicular to the plane of the disk-shaped test element. The test element has a sample application opening for applying a liquid sample, a capillary-active zone, in particular a porous, absorbent matrix, having a first end that is remote from the axis and a second end that is near to the axis, and a sample channel which extends from an area near to the axis to the first end of the capillary-active zone that is remote from the axis.
