为提供ＳＹＮＣＨＲＯＮＣＸ３型全自动生化分析仪钾、钠、氯试剂，在对随机试剂的组成及理化特性进行分析的基础上，设计配方，并反复进行对比调整，最后选出各项参数及测定结果适合检测的配方。结果，自制试剂从理化特性、线性范围、相关回归、精密度、准确度、稳定性及临床应用等方面均与随机试剂相近。说明自制试剂可以替代随机试剂，满足临床需要。 In order to provide potassium, sodium, and chlorine reagents for SYNCHRONCX3 automatic biochemical analyzers, based on the analysis of the composition and physicochemical properties of random reagents, the formulation was designed, and the comparison and adjustment were repeated. Finally, all parameters and measurement results were selected. Test recipe. As a result, self-made reagents were similar to random reagents in terms of physical and chemical properties, linear range, correlation regression, precision, accuracy, stability, and clinical application. Description Self-made reagents can replace random reagents to meet clinical needs.
