Abstract:
Blood samples were detected by 24 blood-glucose meters using glucose oxidase and another 18 glucose meters using glucose dehydrogenase. The plasma glucose was detected by the auto-chemistry analyzer as control. According to ISO1 5197 and EF9-A2, the bias of results from both glucose meters 100% fall in the range of ±0. 56 mmol/L( ＜4. 2 mmol/L) and ≥99. 7% in the range of ±20% ( ≥4. 2 mmol/L), predicted bias were all less than the true bias(Bc). As κ＞0. 6, the results from both glucose meters were in accordance with the results from autochemistry analyzer in judging hyperglycemia ( ＞6. 11 mmol/L) and hypoglycemia ( ＜ 3.89 mmol/L). Between the results from the two blood-glucose meters, κ＜0. 6. The accuracy of both glucose-meters are accepted for the purpose of clinical diagnosis and treatment.
