The present invention provides a device and a process for detecting an analyte in a biological fluid. That device comprises a cover portion with a restricted area for sample application, a separation matrix for separation of the analyte from substances in the sample that can interfere with detection of the analyte and means for detecting the analyte. The restricted area of sample application is less than 90 percent of the cross sectional area of the separation matrix and the separation matrix and the means for detecting analyte are under compression of between 14 to 43 percent. A process comprises applying a sample of fluid to such a device and detecting a signal generated from an interaction between the analyte and the detection means in the device.

L'invention porte sur un dispositif et un procédé pour la détection d'un composé à analyser dans un liquide biologique. Le dispositif comprend un couvercle avec une section restreinte pour l'application d'un échantillon, une matrice pour séparer le composé à analyser d'autres substances présentes dans l'échantillon, lesquelles pourraient interférer avec la détection du composé et le système de détection. La section restreinte pour l'application de l'échantillon représente moins de 90 % de la section transversale de la matrice de séparation; la matrice et le système de détection pour le composé à analyser sont comprimés à 14-43 %. La méthode consiste à appliquer un échantillon du liquide sur ce dispositif et à déceler le signal produit par une interaction entre le composé à analyser et le système de détection.
