Abstract
The invention relates to a reagent and a method of using the same for automatically determining the population of the basophilic leukocytes in the blood. The invention relates more particularly to a new formulation for a differential lysing reagent that lyses all the blood cells except for the basophils, particularly suitable for the measuring principle based on resistivity measurement, that is to say the concentrations of the constitutents and the pH of the solution are suitable for ensuring good electrical conductivity of the medium. The reagent according to the invention will find an application in apparatus for automatically determining blood formulae by means of resistivity variation measurements.
