HbA1c (Glycated Hemoglobin)
The Gold Standard for Diabetes Diagnosis & Long-term Control
Glycated hemoglobin (HbA1c) reflects your average blood glucose level over the preceding 2–3 months. Unlike daily fingerstick tests, it provides a stable, objective window into chronic glycemic exposure, making it the cornerstone of modern diabetes management.
Key Characteristics of HbA1c
Long-term Stability
Minimally affected by short-term fluctuations in diet, stress, or exercise.
Diagnostic Power
International guidelines set ≥ 6.5% as the threshold for diabetes diagnosis.
Patient Convenience
No fasting required. Can be performed at any time of day with high compliance.
HbA1c vs. Daily Monitoring
| Characteristic | HbA1c | Daily Fingerstick |
|---|---|---|
| Time Frame | Past 2–3 months | Single time point |
| Key Factors | Long-term average | Diet, exercise, meds |
| Main Purpose | Diagnosis & Trends | Real-time management |
Clinical Significance
- Complication Risk: High levels correlate with retinopathy and neuropathy.
- Treatment Guidance: Helps clinicians adjust medications or lifestyle.
