Glycosylated Hemoglobin (HbA1c) Test

The glycosylated hemoglobin (HbA1c) test is a blood test that provides valuable information about a person's average blood sugar levels over the past 2-3 months. Hemoglobin is a protein in red blood cells that carries oxygen. When glucose (sugar) in the blood attaches to hemoglobin, it forms HbA1c. The HbA1c test is commonly used to monitor and manage diabetes, as it reflects long-term blood sugar control. It is particularly useful in assessing how well diabetes management measures, such as diet, exercise, and medication, have been working overtime.
