The HbA1c test measures the percentage of hemoglobin in red blood cells that is bound to glucose, reflecting long-term blood sugar control rather than daily fluctuations. Higher HbA1c values indicate poor glucose control and increased risk of diabetes-related complications.

Preparation: No fasting required; can be done at any time of day
Sample Type: Blood sample (from a vein in the arm)
Who Should Take It: Diabetic patients for routine monitoring, individuals with diabetes risk factors, borderline glucose levels, or routine health screenings
Benefits: Tracks long-term sugar control, guides treatment adjustments, reduces complication risk, and helps in early diabetes diagnosis
