An apparatus ana method for testing oral fluids uses a housing (H) containing a chromatographic strip (C) connected to a capillary matrix (W) which extends from the housing for contact with oral fluids. An optional blocking pad (B) can be provided between the strip (C) and the matrix (W). Fluid is taken up by the matrix (W) and transferred to the strip (C) where it reacts with reagents in indicator zones (20) for visual observation through view ports (18).

La présente invention concerne un appareil et un dispositif permettant de tester des fluides buccaux. Ce dispositif met en oeuvre une enceinte (H) contenant une bande chromatographique raccordée à une matrice de capillaires (W) prenant naissance sur l'enceinte et venant au contact des fluides buccaux. Un tampon de blocage (B) facultatif est disposé entre la bande (C) et la matrice (W). Le fluide est prélevé par la matrice (W) puis transféré sur al bande (C) où il réagit avec des réactifs dans des zones de lecture (20) aux fins d'une observation au travers de regards (18).
