Abstract
A microfluidic element for analyzing a bodily fluid sample for an analyte contained therein is provided, the element having a substrate, a channel structure that is enclosed by the substrate, and a cover layer, and is rotatable around a rotational axis. The channel structure of the microfluidic element includes a feed channel having a feed opening, a ventilation channel having a ventilation opening, and at least two reagent chambers. The reagent chambers are connected to one another via two connection channels in such a manner that a fluid exchange is possible between the reagent chambers, one of the reagent chambers having an inlet opening, which has a fluid connection to the feed channel, so that a liquid sample can flow into the rotational-axis-distal reagent chamber. At least one of the reagent chambers contains a reagent, which reacts with the liquid sample.
