Abstract

The present invention provides a test carrier for the analytical determination of a component of a liquid sample, especially of a body fluid, with a carrier layer, which is partly covered by a liquid-absorbing layer which contains a sample application zone and a transport zone, and a reagent layer which is in contact with the liquid-absorbing layer, wherein the reagent layer in contact with the liquid-absorbing layer is so arranged that it does not overlap with the sample application zone and is full-facedly in contact with the liquid-absorbing layer.
