Abstract

Introduction: It is relevant to recognize that the accuracy of glucose measurements performed with glucometers can be influenced by several factors. Objective: The objective of the study was to evaluate the concordance between laboratory and glucometer glucose measurements in patients at a university in Ecuador.

Methods: The study was observational, cross-sectional and prospective. The study population consisted of a total of 138 students enrolled in the Medical School (first semester) of the Universidad Regional Autónoma de los Andes, located in the city of Ambato, Ecuador. SPSS statistical software (version 25) was used and Cohen's Kappa coefficient was calculated.

Results: In the "Normal" measurements according to the glucometer, 23.2 % coincided with the laboratory measurements, showing a certain concordance. However, 22.5 % were categorized differently, indicating discrepancies. In the "Elevated" measurements by glucometer, 31.9 % agreed with the laboratory measurements, showing agreement, but 54.3 % were categorized differently. Cohen's Kappa coefficient was 0.095, with a significance value of 0,266.

Conclusions: Low concordance and nonsignificant association were found between glucose measurements obtained with the glucometer and laboratory measurements.
