For an analytical test element for blood analyses comprising a substrate body (12) having a channel structure (14) for the flow transport of a blood sample from an application site (18) to at least one analytical site (20, 22), the invention proposes that the channel structure (14) has a dilution channel (24) that can be loaded with the blood sample and is provided with separation means (36) for retaining corpuscular blood components and has a sample channel (26) which conveys a blood sample aliquot to be diluted and joins the dilution channel (24) at a mixing site (40).
Pour un élément de test diagnostique pour analyses de sang comprenant un corps de substrat (12) ayant une structure en canal (14) pour le transport du flux d'un échantillon de sang d'une zone d'application (18) vers au moins une zone d'analyse (20, 22), l'invention propose que la structure en canal (14) dispose d'un canal de dilution (24) qui peut être chargé avec l'échantillon de sang et est prévu avec des moyens de séparation (36) pour la rétention des composants sanguins corpusculaires et dispose d'un canal d'échantillonnage (26) qui transmet une aliquote d'échantillon de sang à être dilué et rejoint le canal de dilution (24) au niveau d'une zone de mélange (40).
