Evaluation of hematocrit results of different detection systems / 国际检验医学杂志

ABSTRACT

Objective Using microcentrifugation method (method 1) as the reference method ,to evaluate the consistency of the hematocrit (HCT ) results detected by different types of blood cell analyzers[Sysmex800i (method 2) ,Sysmex1000i (method 3) , XE-2100D (method 4)] .Methods 63 cases of fresh whole blood samples were collected and detected by three blood cell analyzers and method 1 .And the three blood cell analyzers had been calibrated before the tests .Results The correlation analysis of HCT re-sults of method 2 ,method 3 ,and method 4 with method 1 showed the coefficients were 0 .874 4 ,0 .951 2 and 0 .955 5 ,respectively . Using method 1 as the reference method ,the clinical acceptability of three blood cell analyzers were evaluated .The HCT result de-tected by method 4 was unacceptable at two clinical decision levels .Conclusion Investigating the comparability among different blood cell analyzers regularly can effectively guarantee the reliability of test results .
