Abstract

Détermination d'un volume de cellules dans le sang. Dans un volume prédéterminé de l'échantillon 18, on introduit un réactif agglutinant et un volume prédéterminé d'un colorant 22 et les hématies s'agglutinent, ce colorant ayant une concentration connue, on décante 28, 34, 40 les hématies agglutinées et on mesure 50 par colorimétrie la concentration du colorant; le réactif agglutinant a une charge électrique positive élevée, et le colorant est soluble dans l'eau, ne pénètre pas dans les cellules, ne forme pas précipité avec le réactif agglutinant et ne lyse pas les cellules. Détermination des hématies dans des échantillons de sang selon une technique d'analyse en écoulement continu.
