Abstract

Introduction: Diabetes mellitus is not one disease, but rather is a heterogeneous group of multifactorial, polygenic syndromes characterized by an elevated fasting blood glucose (FBG) caused by a relative or absolute deficiency in insulin. Objective: The main objective of this study was to assess the relationship between blood glucose levels and HbA1c in control and newly diagnosed diabetic patients without complications. Methods. The present study was conducted on 75 newly diagnosed type 2 Diabetes mellitus patients (female- 25, male- 50) and the control group consisted of 60 healthy individuals (female-24, male-36). Blood samples were collected in plain vacutainers without any anticoagulant and whole blood collected with EDTA from diabetic patients and control subjects for the estimation of various biochemical parameters. Blood glucose estimation was done by GOD-POD method and HbA1c, creatinine, urea, total protein and albumin were estimated by kit method (ERBA diagnostics Mannheim GmbH). Statistical analysis was done by unpaired t-test and Pearson correlation coefficient. Results: FBS (148.60 ▒ 7.8), PPBS (193.92 ▒ 12.30) mg/dl and HbA1c (6.51 ▒ 0.85) % was significantly higher in type 2 diabetes patients (p<0.0001) as compared to control subjects FBS (95.23 ▒ 6.3), PPBS (121.35 ▒ 9.50) mg/dl and HbA1c (4.58 ▒ 0.32) % (p<0.0001). FBS was found to be highly correlated (r=0.774, p<0.001) with HbA1c as compared to PPBS (r=0.427, p<0.05) in newly diagnosed diabetic patients. Conclusions: Our study showed that FBS is highly correlated to HbA1c as compared to PPBS.
