[0007] Chinese patent 1247982 has reported the reagent that is used for the measurement of hemoglobin and the mensuration of white blood cell in the blood sample, discloses the hemolytic agent that is used to measure leukocyte grouping, but this hemolytic agent obtains in the leukocyte histogram (see figure 1 ), the peak of monocytes (Mo) is not obvious enough, which may easily cause errors in the identification of the instrument software

Abstract
The invention discloses a hemocyte analyzer hemolytic agent. Every 1L of hemolytic agent comprises 5-40.0g of quaternary ammonium salt, 5.0-25.0g of alkali metal chloride, 0.05-5.0g of ethylenediamine tetraacetic acid or ethylenediamine tetraacetic acid derivative, 0.5-5.0ml of inorganic acid, 0.5-8.0g of pH regulator for regulating the pH value to 5.0-8.0, and the balance of water. The invention solves the problem that the peak shapes of lymphocyte, monocyte and granulocyte in a leucocyte histogram of XFA6000-series and XFA6000 Intelligent-series full-automatic hemocyte analyzers produced by Nanjing Pulang Medical Equipment CO, LTD are not obvious or only the wave peaks of the lymphocyte and granulocyte can appear, and also solves a series of problems of insufficient accuracy of classification of leucocytes; and the reagent does not contain any preservative or cyanide, and thus, does not pollute the environment.
Description
technical field [0001] The invention belongs to the field of reagents for medical diagnostic instruments, in particular to a hemolytic agent for blood cell analyzers. Background technique [0002] Diluent and hemolyzing agent are the most commonly used reagents for hematology analyzers in medical testing, and are the key reagents for determining the count or classification of hemoglobin (HGB) and white blood cell (WBC). Under the cooperation of the diluent, the hemolytic agent dissolves the red blood cells (RBC) rapidly on the one hand, releases hemoglobin and combines with the hemolytic agent to form a stable hemoglobin derivative, which can be used to measure HGB; on the other hand, the white blood cells maintain their original shape and Keep a certain volume for WBC counting, and classify leukocytes into three groups according to their size: lymphocytes (LYM), monocytes (Mo), and granulocytes (GRA). [0003] Usually, blood cell analysis is to dilute the blood sample with...
