Abstract

L'invention concerne un procédé de mesure de la valeur d'une fraction sanguine au moyen de données comprenant un ensemble de données unique, le procédé consistant (a) à déterminer plusieurs valeurs de fractions sanguines possibles au moyen de plusieurs dispositifs de calcul de valeur de fraction sanguine, chaque dispositif de calcul de valeur de fraction sanguine faisant appel à l'ensemble de données unique, et chaque valeur de fraction sanguine possible possédant un niveau de confiance qui lui est associé, basé sur au moins une mesure de la qualité; et (b) à procéder à un arbitrage entre les valeurs de fraction sanguine possibles par rapport aux niveaux de confiance pour déterminer une mesure de la fraction sanguine.
