COMPARABILITY OF BECKMAN COULTER DXC 700 AU AND ROCHE COBAS 8000 AT UNIVERSITY MEDICAL CENTER HCMC – BRANCH
Main Article Content
Abstract
Objectives: The study aims to compare the results of glucose, cholesterol, triglyceride, SGPT, SGOT assays using patient samples performed on Beckman Coulter DxC 700 AU and Roche Cobas 8000 at University Medical Center HCMC – Branch 2. Methods: Cross – sectional descriptions. Using 40 blood plasma samples with different concentration/ activity performed assays on two devices Beckman Coulter DxC 700 AU and Roche Cobas 8000. Using scatter and Bland – Altman plot analyzing data. Results: All assays have R2>0,95, the correlation equation with slope belongs to (0,9; 1,1) narrower than the suggested range of EP09-A3 of CLSI. The glucose, cholesterol, triglyceride, SGPT, and SGOT assays have an average deviation between two devices within the allowable limits of performance. Conclusion: Glucose, cholesterol, triglyceride, SGPT, SGOT assays of the same blood plasma sample performed on Beckman Coulter DxC 700 AU and Roche Cobas 8000 have the comparability with slope belongs to (0,9; 1,1) narrower than the suggested range of EP09-A3 of CLSI. The glucose, cholesterol, triglyceride, SGPT, and SGOT assays have an average deviation between two devices within the allowable limits of performance.
