HbA1c, or glycated hemoglobin, is a crucial blood test used to measure the average blood glucose levels over the past two to three months. It provides valuable information about a person’s long-term blood sugar control, particularly in individuals with diabetes. The test works by assessing the amount of glucose that has become attached to hemoglobin, the protein found in red blood cells. As red blood cells typically live for around two to three months, the HbA1c test reflects the average blood sugar levels during that time period.

Maintaining optimal HbA1c levels is essential for managing diabetes and reducing the risk of diabetes-related complications such as cardiovascular disease, kidney disease, nerve damage, and eye problems. Healthcare providers use HbA1c results to monitor the effectiveness of diabetes treatment plans, adjust medications, and make lifestyle recommendations to help patients achieve and maintain target blood sugar levels. Regular HbA1c testing is a critical component of diabetes management, providing valuable insights into a person’s overall blood sugar control and guiding personalized treatment strategies.
