Achieving glycemic control or reduction of hyperglycemia would significantly decrease most of the complicationsassociated with hyperglycemia in diabetes mellitus. It has been stated that measurement of glycosylated hemoglobin(HbA1C) remains the gold standard for the assessment of glycemic control; there is no consensus whether the Fastingor Postprandial is a better predictor of glycemic control in poor resource setting where HbA1C is not easily accessedor available. The aim of this research is to determine fasting and postprandial plasma glucose and their correlationwith HbA1C in glycemic control. A cross sectional case control study was carried out from January, 2023 to July,2023; a total of 203 participants were recruited into the study. Fasting blood glucose (FBG), 2 hours post prandialblood glucose (2HPBG) were determined in all the subjects using the enzymatic glucose oxidase method for glucoseestimation according to the instruction of the manufacturer, while HbA1C was determined using BoroaffinityChromatographic method according to the instruction of the manufacturer. Statistical data analysis was carried outusing SPSS software (Version 25.0, IBM Corp., Armonk, New York USA), and p<0.001 were defined as statisticallysignificant; the correlation between the parameters was carried out using Pearson’s correlation. Both the FBG and the2HPBG showed positive correlation with HbA1C in the diabetic and control subjects; however, the level of correlationvaries. The correlation of FBG and 2HPBG with HbA1C is directly proportional to the concentration of blood glucoselevel. The FBG for the control and the subjects are 7.40±1.59 and 143.67±5.01, with HbA1C of 4.45±0.05; 6.26±1.47respectively. The 2HPBG for the control and the subjects are 120.70±1.75 and 192.92±7.05, with HbA1C of5.56±0.07; 7.82±0.22 respectively. The FBG correlation to HbA1C is r= 0.875, p<0.001; while 2HPBG is r= 0.908, p<0.001. The study showed positive correlation of FBG and 2HPBG with HbA1C, since HbA1C is the value of thepercentage concentration of glucose at a given period of time; FBG, 2HPBG and HbA1C can be used to evaluate thedegree of glycemic control in diabetic patients’ management, in order to minimize or avoid diabetic complications.Keywords: FBG, PBG, Diabetes, HbA1C, Correlation, Complications
