床旁检验血糖仪与生化分析仪血糖测定结果比对分析

Comparison of POCT blood glucose meter with the automatic biochemical analyzer

目的对中山医院床旁检验(POCT)血糖仪与全自动生化分析仪血糖测定结果进行比对分析和偏倚评估,以保证血糖仪检测结果的一致性。方法参照《便携式葡萄糖仪血液葡萄糖测定指南》,采集肝素钠抗凝静脉血10份,血糖水平分布在3.20～25.81mmol/L。在POCT血糖仪和生化分析仪上重复测定3次,以生化仪为靶仪器,计算相对偏倚。结果 42台血糖仪中的38台与生化分析仪测定值相对偏倚在1%～13%,符合要求。结论通过对中山医院POCT血糖仪与生化分析仪血糖测定结果的比对和偏倚评估,评价血糖仪检测的准确性,以更好地规范医院床旁血糖仪的使用。

Objective To analyze the comparison and bias of POCT blood glucose meter with the automatic biochemical analyzer for ensuring the consistency of the blood glucose meter test results.Methods sodium heparin anticoagulant blood of 10 copies were acquired,distribution of blood glucose levels between 3.20-25.81 mmol/L.Measurements were three times repeatedly on the POCT glucose meters and biochemical analyzer,biochemical analyzer for the target instrument to calculate the relative bias.Results Relative bias of 38 of the 42 blood glucose meters were from 1% to 13.0%,in line with requirements.Conclusion The hospital POCT glucometer biochemical analyzer glucose can evaluate the accuracy of blood glucose meter testing,which can regulate the use of blood glucose meter in hospital.
