Comparison of handheld glucose meter and Olympus AU640 biochemistry analyzer

Objective: To comprehend the concordance of the test results by the handheld glucose meter and the biochemistry analyzer. Methods: The blood glucose samples (low, medium and high levels) were tested by 25 blood glucose meters and the Olympus AU640 biochemistry analyzer. The results and the bias in testing each level of glucose samples were compared and analyzed. Results: The bias reached 22.3% in testing high glucose specimen by 1 of the 25 glucose meters (> 20% as unqualified). The bias was -0.3% to 11.8% in testing low glucose samples,-2.4% to 7.9% in mid-level glucose samples and -8.9% to 7.8% in high glucose samples by the handheld glucose meters. Conclusions: The concordance of the test results by the handheld glucose meter and the biochemistry analyzer is good. The results are reliable, but quality control on the blood glucose meters should be regularly carried out.
