Comparative Study of Oral Glucose Tolerance Test Levels in Pregnant Women Using Glucometer and Laboratory Glucose Oxidase Methods

Abstract

Oral glucose tolerance test (OGTT) is a medical test utilized mostly to resolve border results involving glucose concentrations. This study is aimed at establishing an existence of relationship of OGTT glucose concentrations between glucose oxidase and glucometer methods. Blood samples were collected from hundred (100) pregnant women with risk factors for gestational diabetes mellitus. The glucose concentrations were assayed using glucose oxidase and glucometer methods. The results were analyzed using student t-test and Pearson correlation. The results established a significant increase (P< 0.05) of some of components of OGTT in glucometer method as compared to glucose oxidase method. A correlational study established a correlationship at only the fasting levels of the assay. The findings revealed that results from glucometer seem to be higher when compared to glucose oxidase method. Hence, glucometer should be restricted to only medical screening and not clinical use. Also users of glucometers should be educated on the inaccuracies surrounding the use of glucometer.
