CA 2164725

A method is provided for measuring an analyte in sample comprising adding substantially transparent particles to a sample in solution or suspension, said particles having an affinity for said analyte; fractionating the particles from the solution or suspension to form a particle- rich fraction and a substantially particle-free fraction; optically reading the particle-rich fraction at a first wavelength; optically reading the substantially particle-free fraction at a second wavelength; and correlating the readings through the particle-rich fraction and the substantially particle-free fraction to obtain a quantitative determination of the analyte originally present in the sample.

L'invention concerne un procédé servant à mesurer un analyte dans un échantillon et consistant à ajouter des particules sensiblement transparentes à un échantillon dans une solution ou une suspension, ces particules ayant une affinité pour cet analyte; à fractionner les particules de la solution ou de la suspension pour obtenir une fraction riche en particules et une fraction pratiquement exempte de particules; à lire optiquement la fraction riche en particules à une première longueur d'ondes; à lire optiquement la fraction pratiquement exempte de particules à une seconde longueur d'ondes; et à mettre en corrélation les lectures dans la fraction riche en particules et la fraction pratiquement exempte de particules afin d'obtenir une détermination quantitative de l'analyte présent à l'origine dans l'échantillon.
