What is Glycated Hemoglobin (HbA1c)?

Glycated Hemoglobin is measured as part of a diabetes & blood sugar panel. Your HbA1c is below 5.7% — your average blood sugar over the past 3 months has been in the healthy range. No sign of diabetes or prediabetes.

What does a high Glycated Hemoglobin mean?

Your HbA1c is elevated. 5.7–6.4% = prediabetes. 6.5%+ = diabetes. This reflects your average blood sugar over the past 3 months — not just today's reading. Lifestyle changes can significantly reduce this.

If markedly elevated: Your HbA1c indicates poorly controlled diabetes. Long-term high blood sugar damages nerves, kidneys, and blood vessels. Working with your doctor on a management plan is important.

Understand your whole report, not just one number

A single value rarely tells the full story — Glycated Hemoglobin is best read alongside the rest of your panel. Paste your values or upload your report and get a plain-English explanation of every marker, with the important results flagged.
