The invention concerns an analytical test element for the determination of an
analyte in a liquid containing an inert carrier, a detection element and a channel
capable of capillary liquid transport which has a sample application opening at
one end and a vent opening at the other end of the channel capable of capillary
liquid transport, wherein the channel capable of capillary liquid transport is
formed at least partially by the carrier and the detection element and extends
in the direction of capillary transport from the sample application opening at
least to the edge of the detection test element that is nearest to the vent opening
and wherein a notch is located in one of the surfaces forming the channel capable
of capillary liquid transport at the edge of the test element forming the sample
application opening so that one side of the edge of the test element forming the
sample application opening is at least partially discontinuous and the surface
opposite to the notch is exposed. It also concerns the use of the said analytical
test element for the determination of an analyte in a liquid as well as a method
for the determination of an analyte in a liquid sample with the aid of the said
analytical test element.
