便携式与经典式血乳酸盐测试仪的标准值比较

Standard values of portable lactate-scout versus classic blood lactate analyzer

背景:血乳酸值有着广泛的影响力及重要性,因此,血乳酸仪也得到了广泛的应用,其种类繁多、原理也各不相同。目的:对比新型的便携式乳酸仪与经典式血乳酸盐测试仪测试结果,判断新型便携式乳酸盐分析仪测定血乳酸的准确性及其应用价值。方法:同时利用便携式和经典式血乳酸盐分析仪测量受试者运动前、后的血乳酸值,将两种方法的测量结果进行比较。结果与结论:便携式和经典式血乳酸盐分析仪测量结果没有一致性,两者不能相互替代。便携式和经典式血乳酸盐分析仪测量结果互相比较,相关系数r=0.914,P<0.01;便携式血乳酸盐分析仪测试值=1.895×经典式测试值+2.003,R2=0.836。提示,两种方法测试结果差值较大,不能相互替代,必要时,可以考虑利用回归方程进行血乳酸值相互推算。

BACKGROUND：Blood lactate value has extensive influence and significance,therefore,blood lactate also widely applied,which has different variety and principles.OBJECTIVE：To compare test results between the new portable lactate-scout and classic blood lactate analyzer,and to judge accuracy and its application value of new portable lactate-scout.METHODS：The blood lactate value of subjects was measured prior to and after exercise using portable and classic type blood lactate analyzer,and the results were compared.RESULTS AND CONCLUSION：There was no consistency of measurement result between portable and classic type blood lactate analyzers,and they could not substitute mutually.The results were analyzed by regression equation with correlation coefficient r = 0.914,P 0.01,the test value of portable lactate-scout = 1.895 ×（classic） ＋ 2.003,R2=0.836.The results reveled that there are great difference of test results between two methods,which can not substitute mutually.Regression equations can be used to calculate blood lactate values between two methods if necessary.
