Abstract

L'invention concerne un procédé d'affichage de résultat de mesure qui affiche, sur un écran, un résultat de mesure obtenu par l'imagerie d'une réaction d'agrégation du sang dans chacun des réacteurs (puits (W)) sur une microplaquette (20) destinée à introduire séparément un échantillon et un réactif, et à effectuer une réaction d'agrégation du sang. Une unité d'extraction (34) extrait un résultat de mesure correspondant à l'élément d'extraction entré dans une unité de mesure correspondant à l'élément d'extraction. Une unité de sortie (32) délivre le résultat de mesure extrait. Ainsi, il est possible d'afficher un résultat de mesure spécifié sur un simple écran.
