Abstract: The present disclosure discloses a reagent for differentiating and counting leukocytes which includes: (1) cationic cyanine compounds selected from those having the following general formulae I and II; (2) cationic surfactants selected from those having the following general formulae III, IV and/or V; (3) at least one nonionic surfactant; and (4) optionally, at least one anionic compound selected from those having one or more carboxyl or sulphonyl groups; and optionally includes alcohol compounds. Also disclosed is a kit comprising the reagent for differentiating and counting leukocytes. Further disclosed is a method for differentiating and counting leukocytes using the reagent and kit. Use of the reagent, kit and method disclosed enables the identification of leukocytes in blood samples into five subtypes in a very short time, or at least achieves the differentiation and counting of four leukocyte groupings. Moreover, immature and abnormal cells can be identified.

Abstract: A reagent for blood analysis includes: (1) a compound having the general formula I; and (2) at least one surfactant selected from cationic surfactants and nonionic surfactants. In another aspect a method for differentiating and counting blood cells is provided, the method includes the following steps: (a) mixing a blood sample with the reagent for blood analysis according to the present disclosure to form a cell suspension; (b) detecting scattered light signals and fluorescence signals of cells in the blood sample; and (c) differentiating and counting the cells in the blood sample based upon the scattered light signals and fluorescence signals. The reagent for blood analysis may be effective for identifying and counting erythroblasts and/or basophils in a blood sample to be detected, and meanwhile counting leukocytes therein.
