Abstract

L'INVENTION SE RAPPORTE A L'ANALYSE BIOLOGIQUE. ELLE CONCERNE UN PROCEDE POUR DETERMINER LA PRESENCE D'UN ANALYTE DANS UN FLUIDE CORPOREL, CARACTERISE EN CE QU'IL COMPREND ESSENTIELLEMENT LES ETAPES SUIVANTES: A.MISE EN CONTACT D'UNE SURFACE 2 AVEC LE FLUIDE 11, CETTE SURFACE ETANT REVETUE D'AGENTS RECEPTEURS 10 SPECIFIQUEMENT REACTIFS AVEC L'ANALYTE; B.MISE EN CONTACT DE LA SURFACE REVETUE AVEC UN REACTIF IMMUNOLOGIQUE 13 COMPRENANT UN COMPOSE IMMUNOLOGIQUE 14 SPECIFIQUEMENT REACTIF AVEC LES REACTIFS RECEPTEURS OU AVEC UN COMPLEXE DE L'ANALYTE ET DU REACTIF RECEPTEUR, CE COMPOSE IMMUNOLOGIQUE ETANT APPLIQUE SUR DES INDICATEURS A REACTANCE 15 QUI SONT DES PARTICULES CAPABLES DE MODIFIER LA REACTANCE ELECTRIQUE; C.ENLEVEMENT DU REACTIF IMMUNOLOGIQUE N'AYANT PAS REAGI DE LA SURFACE; D.MESURE DE LA REACTANCE ELECTRIQUE DE LA SURFACE. UTILISATION PAR LES LABORATOIRES MEDICAUX D'ANALYSES.THE INVENTION RELATES TO BIOLOGICAL ANALYSIS. IT CONCERNS A PROCESS FOR DETERMINING THE PRESENCE OF AN ANALYTE IN A BODY FLUID, CHARACTERIZED IN THAT IT ESSENTIALLY INCLUDES THE FOLLOWING STEPS: A. CONTACT OF A SURFACE 2 WITH THE FLUID 11, THIS SURFACE BEING COATED WITH ' RECEIVING AGENTS 10 SPECIFICALLY REACTIVE WITH THE ANALYTE; B. CONTACT OF THE COATED SURFACE WITH AN IMMUNOLOGICAL REAGENT 13 INCLUDING AN IMMUNOLOGICAL COMPOUND 14 SPECIFICALLY REACTIVE WITH RECEIVING REAGENTS OR WITH AN ANALYTE AND RECEIVING REAGENT COMPLEX, THIS IMMUNOLOGICAL COMPOUND BEING APPLIED ON REACTOR INDICATORS 15 ARE PARTICLES CAPABLE OF MODIFYING ELECTRICAL REACTANCE; C. REMOVAL OF IMMUNOLOGICAL REAGENT THAT HAS NOT REACTED FROM THE SURFACE; D. MEASUREMENT OF THE ELECTRICAL REACTANCE OF THE SURFACE. USE BY MEDICAL ANALYSIS LABORATORIES.
