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
The invention belongs to medical diagnostic equipment and use the reagent field, be specifically related to a kind of cellanalyzer hemolytic agent.
Background technology
Dilution and hemolytic agent are the most frequently used reagent of blood analyser in the medical test, are the key reagents of Measuring hemoglobin (HGB) and leucocyte (WBC) counting or classification.Hemolytic agent makes on the one hand rapidly dissolving of red blood cell (RBC) under the mating reaction of dilution, discharge haemoglobin and be combined the stable haemoglobin dervative of formation with hemolytic agent, so that quantitative determination HGB to be provided; Leucocyte is kept original form on the other hand, and keeps certain volume, for the WBC counting, and comes that according to leukocytic size leucocyte is carried out three and hives off: lymphocyte (LYM), monocyte (Mo), granulocyte (GRA).
Usually, blood cell analysis is to use the diluted blood sample, thereby then analyzing a part has diluted blood sample and has measured red blood cell and platelet parameter, again hemolytic agent is added in all the other blood samples that diluted, go out red blood cell and blood platelet, content of hemoglobin is measured, the mensuration of white blood count and differential in order to carry out.
Because red blood cell, leucocyte, blood platelet and hemoglobin concentration are to the susceptibility of chemical reagent, be difficult to find a kind of both the degraded also can close the combination that needs ground changes the chemical reagent that needs the cell characteristics analyzed and hemoglobin parameters, particularly under the condition that changes operating temperature.The physical parameter of cell can be subject to the impact of diluent ingredient and analytical approach, no matter be automatic, semi-automatic or hand-manipulated, existing dilution has all been stipulated the experimental technique that necessary usefulness is special or has been used proprietary instrument, therefore, existing dilution is can not be general or be used for kinds of experiments instrument or experimental technique.
United States Patent (USP) 4255385 has been reported method and the reagent that is used for measuring the blood sample haemoglobin, the document disclose a kind of for dissolving and dilution whole blood sample in order to carry out the reagent of cell analysis, but this reagent contains the potassium ferricyanide that is useful on Measuring hemoglobin.
United States Patent (USP) 5227304 has been reported a kind of reagent system of using of complexity when the enterprising promoting circulation of blood cell count of Cell Dyn board blood analyser and magnitude classification.This reagent system comprises thinning agent and the scaling agent that a kind of grade is oozed, and wherein thinning agent is comprised of imidazoles organic buffer liquid, antiseptic, inorganic salts and pH adjusting agent, but it is not suitable for other types.
Chinese patent 1247982 has been reported and has been used for the measurement of blood sample haemoglobin and the reagent of determination of white cells, disclose and be used for measuring the hemolytic agent that leucocyte hives off, but (see figure 1) in the leucocyte histogram that this hemolytic agent obtains after use, the crest of monocyte (Mo) is obvious not, easily causes the error of instrument software identification.
Summary of the invention
Goal of the invention: for the problems of the prior art, the purpose of this invention is to provide a kind of cellanalyzer hemolytic agent.
Technical scheme: in order to solve the problems of the technologies described above, the invention provides a kind of cellanalyzer hemolytic agent, in the 1L hemolytic agent:
