Diabetes is diagnosed when your HbA1C is 6.5% or above, indicating average blood glucose levels of 140 mg/dL or higher, or 7.8 mmol/L and above. Effective management is critical to reduce complications and improve health outcomes. The normal range for HbA1C levels is below 5.7%. A normal HbA1C level is below 5.7%. This test measures blood sugar with the aim of diagnosing diabetes. Hemoglobin A1c (HbA1c) is a measure of average blood sugar. Learn how it’s measured, what’s considered normal HbA1c, what HbA1c level you’ll want to target if you have diabetes, and why it matters. Glycosylated Hemoglobin Normal Range Glycosylated hemoglobin, commonly known as HbA1c, is a crucial marker in the management and diagnosis of diabetes. Understanding the normal range for glycosylated hemoglobin can significantly impact how individuals and healthcare providers monitor and manage blood sugar levels over time. In this article, we will delve into the normal ranges for HbA1c, the factors influencing these levels, and how to interpret the results for effective diabetes management.
