Test device (A) for determining analytes in a liquid sample comprises a flat carrier that includes specific reagents (I). To ensure long-term stability, (I) are embedded in a combination of: (a) amino-carboxylic acids (IIa) or high molecular weight, peptide-linked compounds (IIb), prepared from aminocarboxylic acids; and (b) polyhydroxy compounds (III). An independent claim is also included for a method for preparing test devices, particularly (A), by treating the carrier with an aqueous solution that contains catalytically active and/or inactive proteins and a combination of (a) and (b), then drying. 1. Trockenchemischer Test, 2. Die Erfindung betrifft ein langzeitstabilisiertes Mittel zum Nachweis von Bestandteilen in Flüssigkeiten, bestehend aus: flächenförmigemTräger, katalytisch aktiven und/oder katalytisch nichtaktiven Eiweißkörpern und monomeren oder peptidartig-verküpften Aminocarbonsäuren und Polyhydroxyverbindungen. Der Träger weist Langzeitstabilität auf.
