Title
(EN) HEMATOCRIT AND ANALYTE CONCENTRATION DETERMINATION
(FR) DETERMINATION DE LA TENEUR EN HEMATOCRITE ET EN UNE SUBSTANCE A ANALYSER
Abstract
(EN)
A method to determine an analyte concentration of an anticoagulated plasma by performing at least two different measurements on a mixture of a blood sample corresponding to said anticoagulant plasma and of liquid reagent is described. The method comprises a) mixing a volume of said blood sample with a five-fold, or more, volume of said liquid reagent, b) performing said at least two measurements on said mixture, at least one of which correlates with the hematocrit of said blood sample and at least one of which correlates with said analyte concentration, and c) computing the results from the measurements when the volumes in a) are precise and accurate or when the hematocrit of said blood sample in b) is known to determine said analyte concentration of said anticoagulated plasma. In addition, a measurement and determination device for performing measurements on blood, anticoagulated blood and/or anticoagulated plasma samples, and an equipment kit are described.

L'invention porte sur un procédé de détermination d'une teneur en une substance à analyser d'un plasma anticoagulé au moyen d'au moins deux mesures différentes d'un mélange d'un prélèvement sanguin correspondant audit plasma coagulé et d'un réactif liquide. Le procédé consiste à a) mélanger un volume dudit prélèvement sanguin avec cinq fois au moins le volume dudit réactif liquide, b) effectuer au moins deux mesures sur ledit mélange dont au moins un est en corrélation avec l'hématocrite du prélèvement sanguin et dont au moins un est en corrélation avec la teneur en une substance analysée et c) calculer les résultats des mesures lorsque les volumes dans a) sont précis ou lorsque l'hématocrite du prélèvement sanguin dans b) est supposé déterminer la teneur en une substance à analyser dudit plasma anticoagulé. Par ailleurs, l'invention porte sur un dispositif de mesure et de détermination permettant de mesurer des prélèvements de sang, le sang anticoagulé et/ou de plasma anticoagulé, ainsi que sur un kit d'équipement.
