[0029] Reagent for three-classification blood cell analyzer of the present invention

[0030] (1) The formula of the diluent:

[0031] Sodium chloride 8.2 g / L

[0032] Disodium hydrogen phosphate 5.8g / L

[0033] Potassium dihydrogen phosphate 0.27g / L

[0034] Potassium chloride 0.2 g / L

[0035] EDTA-2Na 0.3g / L

[0036] Ethylene glycol phenyl ether 3ml / L

[0037] Weigh or measure 8.2g of sodium chloride, 5.8g of disodium hydrogen phosphate, 0.27g of potassium dihydrogen phosphate, 0.2g of potassium chloride, 0.3g of EDTA-2Na and 3ml of ethylene glycol phenyl ether, and add them to 1L to In ionized water, stir and dissolve evenly at room temperature, and obtain a dilution after filtering with a filter membrane with a pore size of 0.8 microns in a clean environment. The pH value of the dilution is measured to be 7±0.20; the conductivity of the dilution is 180±0.5mS / cm; the osmotic pressure of the diluent is 290±10 mosm / kg.

Abstract

The invention relates to a reagent for a three-classification blood cell analyzer. The reagent comprises a diluent, a hemolytic agent and a cleaning liquid. The diluent is composed of sodium chloride,disodium hydrogen phosphate, monopotassium phosphate, potassium chloride, EDTA-2Na, ethylene glycol monophenyl ether and water; the hemolytic agent consists of disodium hydrogen phosphate, monopotassium phosphate, cetyl trimethyl ammonium bromide, polyethylene glycol octylphenol ether, sodium nitrite and water; and the cleaning fluid consists of sodium chloride, sodium sulfate, an antibacterial agent and a surfactant. The prepared regent for the three-classification blood cell analyzer is low in cost and high in stability, can be universal in multiple models, is reliable in performance and meets the clinical requirements.

Description

technical field [0001] The invention belongs to a reagent for a medical testing instrument, in particular to a reagent for a three-class blood cell analyzer. Background technique [0002] The three-differential blood cell analyzer is currently a blood routine testing instrument commonly used in my country. For a long time, such instruments and reagents have been imported in my country. Due to the high price of reagents and untimely supplies, it has brought heavy economic burdens to hospitals and patients. and inconvenience. Among the three-classification blood cell analyzers commonly used in my country, there are no less than 20 brands of various brands. Due to the differences in biological dilution ratios and measurement methods of various instruments, the reagent formulas of various instruments are different, and the blood cells of different models and manufacturers are different. The analyzer must use special matching reagents, which is an important difficulty in the devel...
