Abstract

Diabetes Mellitus (DM) is a chronic metabolic disorder characterized by hyperglycemia, with Type 2 DM (T2DM) being the most prevalent form. Effective glycemic monitoring is crucial to prevent complications. Glycosylated hemoglobin (HbA1c) reflects long-term glucose control (2-3 months), while fasting blood glucose (FBG) provides short-term insights.

Objective: To evaluate the correlation between FBG and HbA1c in T2DM patients.

Methods: This cross-sectional study included 50 T2DM patients (aged 35-50 years) at Metro Hospital, Jabalpur. FBG was measured using the Glucose Oxidase-Peroxidase method, and HbA1c via nephelometry. Descriptive statistics and Pearson correlation were performed.

Results: Mean FBG was 140.2 ± 30.1 mg/dL, and mean HbA1c was 7.2 ± 1.5%. A strong positive correlation existed between FBG and HbA1c (r = 0.85, p < 0.001).

Conclusion: HbA1c strongly correlates with FBG and is a reliable biomarker for long-term glycemic control. Combined monitoring of both parameters is essential for diabetes management.
