The invention relates to an apparatus and a method for determining an analyte in a fluid. Provided in the device is a stirring zone formed in an optionally microfluidic three-dimensional structure, into which stirring zone a sample of the fluid can be introduced and in which there is a stirring device which can be operated in a contactless manner and is optionally designed as a microstirrer, the stirring device being configured so as to stir the sample of fluid introduced into the stirring zone and being loaded with at least one reagent which reacts with the analyte. The invention also provides a stirring device which can be operated in a contactless manner and is optionally designed as a microstirrer, the stirring device being loaded with the at least one reagent which reacts with the analyte.

Apparatus and method for determining an analyte in a fluid

An analytical test element for determining at least one analyte in a liquid is provided comprising a support, at least one detection element, and a channel capable of capillary liquid transport which is at least partially formed by a hydrophilic network, one side of which is at least partially in contact with the inner space of the channel and the opposite side of which is at least partially in contact with the detection element such that liquid can be transported from the channel across the network to the detection element. The invention also concerns the use of the analytical test element to determine an analyte in a liquid and a method for determining at least one analyte in the liquid with the aid of an analytical test element.
