The influence of hematocrit on the consistency between blood glucose meters and automatic biochemical analyzer for testing blood glucose of peripheral blood and venous blood / 中国医学装备

ABSTRACT

Objective:To study the influence of hematocrit on the consistency between blood glucose meters and automatic biochemical analyzer for testing blood glucose of peripheral blood and venous blood.Methods: 200 cases of diabetic and non-diabetic patients were selected in our hospital from January 2013 to September 2015, in which 124 cases were diabetics and 76 cases were non-diabetics. All the selected patients were treated with venous blood and peripheral blood glucose testing by the SIEMENS ADVIA1800 full automatic biochemical analyzer and three brand of blood glucose meters (Reiter GM300, Arkray GT-1920, Johnson & Johnson One Touch), comparing their consistency.Results: The hematocrit range was 35.1~51.6%, accounted for 91.0%(182), 25.0~35.0% of patients accounted for 9.0%(18), and average hematocrit was (42.3±4.2). When hematocrit was 35.1~51.6%, the correlation of automatic biochemical analyzer and Reiter GM300 blood glucose meter was high and stable, followed by Arkray GT-1920 and Johnson &Johnson One Touch. When hematocrit was 25.0~35.0%, the correlation of automatic biochemical analyzer and three blood glucose meters were high than hematocrit was 35.1~51.6%. There was no significant difference between SIEMENS ADVIA1800 automatic biochemical analyzer and Reiter GM300 about monitoring the blood glucose results, but there were significant differences between Johnson and Johnson One Touch and Arkray GT-1920.Conclusion: The automatic biochemical analyzer and three blood glucose meters have good correlation. When hematocrit is greater than 35%, the correlation is lower; when hematocrit is less than 35%, the correlation increases.
