泰尔茂血糖仪与日立7180生化分析仪检测血糖结果相关性分析

摘要

Objective To compare and analyze the results of patients' blood sugar value tested by Terumo glucometer and Hitachi 7180 biochemical analyzer, and to analyze their correlation. Methods Fifty blood samples with different blood sugar values. Terumo glucometer was used to test blood sugar for three times and an average value was calculat-ed;full-automatic Hitachi 7180 biochemical analyzer was used to test blood sugar for three times by serum centrifuga-tion of 3000 rpm, and an average value was calculated. SPSS software was used for analysis. Results Precision of Teru-mo glucometer CV% was less than 5%, and the relative bias accorded with related requirements. Compared with the test results by Hitachi 7180 full-automatic biochemical analyzer, results of blood sugar by Terumo glucometer were all within the allowed range. Standard deviation of sample average of 50 samples tested by Terumo glucometer was (7.51±0.69), and the standard deviation of sample average of samples tested by Hitachi 7180 biochemical analyzer was (7.37±0.66). Results of blood sugar tested by Terumo glucometer and Hitachi 7180 biochemical analyzer were not statistically different (t=0.15, P>0.05); correlation coefficient R2 of Terumo glucometer and Hitachi 7180 biochemical analyzer was 0.9739. Conclusion Correlation between glucometer and full-automatic biochemical analyzer in testing blood sugar is favorable, which can be used for blood sugar testing for diabetic patients, but the blood sugar value tested by biochemi-cal analyzer must be taken as diagnostic basis.%目的：对我院在用的泰尔茂血糖测定仪检测患者血糖结果与全自动日立7180生化仪检测血糖值分析比较，分析其相关性。方法采用血糖值不同的50份血液标本，使用泰尔茂血糖测定仪测3次，取均值；3000转/min离心取血清在全自动日立7180生化分析仪上测定3次，取均值，用SPSS软件进行分析。结果泰尔茂血糖测定仪检测精密度CV%小于5%，相对偏倚符合相应要求。与日立7180全自动生化仪测定值相比，泰尔茂血糖仪检测血糖结果均在允许范围内。泰尔茂血糖仪测定50份样本的均数±标准差为（7.51±0.69），日立7180生化仪血糖测定的均数±标准差为（7.37±0.66），泰尔茂血糖仪和日立7180生化仪血糖测定值之间无统计学差异（t=0.15，P>0.05）；与日立7180生化分析仪相关系数R2=0.9739。结论血糖仪与全自动生化仪测定血糖的相关性良好，用于糖尿病患者血糖检测，但是一定要以生化仪测定的血糖值为诊断±据。
