Comparing Glucose Results Obtained from Okmeter in Emergency Unit with Laboratory Results Using Automated Machine in KHMC

Objectives: The purpose of this study was to compare the results of the glucose blood test measurements obtained using OKmeter in emergency unit with laboratory results using automated machine in KHMC.
Method: A method-comparison design was used. The analysis applied on 120 patients by using OKmeter and clinical laboratory analyzer (Hitachi 902). A t test was used to determine differences in glucose values obtained via the two methods. Differences and limits of agreement were calculated.
Results: The result you obtain from your meter may differ somewhat from your laboratory test due to different factors and conditions. Meter results can be affected by factors and conditions that do not affect laboratory tests in the same way. You may still have a variation from the result because blood glucose levels can change significantly over short periods of time, especially if you have recently eaten, exercised, taken medication, or experienced stress. In addition, if you have eaten recently, the blood glucose from finger stick can be up to 70 mg/dl higher than blood drawn from a vein (venous sample). Therefore, it is best to fast for eight hours before doing comparison tests. Factors such as the amount of blood cells in the blood (a high or low hematocrit) or the loss of body fluid (severe dehydration) may also cause a meter result to be different from a lab result.
Conclusion: Regression analysis shows a very strong positive relation (Pearson correlation r =0.978) between the values of the blood glucose testing using OKmeter in emergency unit with laboratory results using automated machine in KHMC. Laboratory glucose values OKmeter in emergency unit using in one sample t-test (t1,117 =0.053) with mean 149.3 and 95% confidence interval of the difference, while the machine (Hitachi 902) values ( t2,117 = 0.015) with mean 144.10, and Reliability statistics results (Cronbach's alpha 0.988).
