Abstract
L'invention concerne un dispositif à base d'enzymes et un procédé de fabrication du dispositif de longue conservation. Ce dispositif comprend une bande de test en phase sèche utile pour détecter la présence et la teneur en acide urique dans un échantillon liquide (comme par exemple l'urine) et présente une solution de travail contenant de l'uricase stabilisée imprégnée dans l'échantillon. L'invention concerne aussi des procédés de fabrication du dispositif permettant de conserver la stabilité de la solution de travail, plus particulièrement de ses composants enzymatiques. L'invention concerne en outre un procédé d'élaboration de la mesure de l'acide urique en une seule opération consistant à appliquer un échantillon liquide sur la bande de test du dispositif.
