What Does a HbA1c Test Measure?
The HbA1c test measures the percentage of hemoglobin in your red blood cells that has glucose attached to it, reflecting your average blood sugar control over the past 2-3 months. Unlike a fasting glucose test that captures a single moment, HbA1c shows the bigger picture of blood sugar management and is the gold standard for diagnosing and monitoring diabetes.
How the Test Works
The HbA1c test is performed via a standard blood draw at any Quest Diagnostics location. Your sample is sent to a CLIA-certified lab for analysis. Results are typically available within 1-2 business days in your JustLabs account.
