血浆葡萄糖和血清葡萄糖测定结果的差异评估

摘要

目的 评价血浆葡萄糖和血清葡萄糖测定结果的差异,并探讨血浆葡萄糖测定结果是否优于血清葡萄糖测定结果.方法 对该市某小区健康查体人员200例,同时抽取2份血样,一份用氟化钠抗凝管分离血浆;另一份用含分离胶的促凝管分离血清.2份血样同时测定葡萄糖水平,用Excel软件分析2组数据的相关性,并用SPSS 13.0软件对测定结果进行处理,分析2组数据的差异性.结果 血浆葡萄糖和血清葡萄糖测定结果相关性好,回归方程:Y=0.926 2X-0.434 4;r2=0.973 1.血浆葡萄糖平均值5.72 mmol/L;标准差1.22.血清葡萄糖平均值4.86 mmol/L;标准差1.14.两种方法的检测结果差异有统计学意义(P<0.01).结论 血浆葡萄糖和血清葡萄糖测定结果相关性好,但2组结果间存在较大差异.%Objective To evaluation the differences between glucose level in plasma and serum to analyze whether the results of plasma glucose would be better than serum glucose. Methods Inhabitants in a residential district in Xi'an were enroiled. Blood samples , anticoagulated by NaF and not anticoagulated,were collected from all subjects at the same time and detected for the concentration of glucose. Correlation and difference between the data from the two groups were analyzed by using Fxcel and SPSS 13. 0 software respectively. Results There was fine correlation between the results of plasma and serum glucose(Y=0. 926 2X-0. 434 4,r2 =0. 9731). But there was statistical difference between the resutts of plasma and serum glucose(P＜O. 01). Conclusion There is fine correlation between the results of plasma and serum glucose,but there is difference between them.
