Hemoglobin A1c reflects average blood sugar levels over time, helping diagnose and manage diabetes.
High A1c levels are linked to complications like heart disease, kidney damage, vision problems, and nerve damage. Low A1c levels may signal frequent low blood sugar episodes, which can be dangerous.
Monitoring and controlling A1c is essential to prevent these health risks.
Hemoglobin A1c, or HbA1c, is a form of hemoglobin that binds to glucose in the blood. It reflects the average blood sugar (glucose) levels over the past two to three months, providing a long-term view of blood sugar control. Hemoglobin A1c is a crucial biomarker in diagnosing and managing diabetes and prediabetes.
This test helps doctors assess how well blood sugar is being controlled. That is essential to prevent complications such as heart disease, kidney damage, and vision problems. Unlike daily blood sugar readings, the Hemoglobin A1c test offers a bigger picture of glucose management. It is vital for both diagnosing diabetes and evaluating how well treatment plans are working.
Hemoglobin A1c testing is commonly prescribed in situations where long-term blood sugar control needs to be assessed. This test is also part of routine screenings for high-risk individuals or those already diagnosed with diabetes.
Here are common situations when the Hemoglobin A1c test might be recommended:
The Hemoglobin A1c test is a blood test that measures the percentage of hemoglobin bound to glucose. Because hemoglobin is part of red blood cells, which have a lifespan of around 120 days, the A1c test reflects an average of blood sugar levels over the past two to three months.
This test is typically conducted as part of a routine blood panel during medical checkups for people at risk of diabetes or for those already managing the condition. It’s also commonly included in comprehensive metabolic panels (CMP) or diabetic care assessments.
Preparations:
The normal range of Hemoglobin A1c depends on the individual’s health status. Below are the ranges for both adults and pregnant women:
Note: The units of measurement and the normal ranges can differ depending on the laboratory and the specific methods used.

High Hemoglobin A1c levels suggest that blood sugar has been elevated over the past few months. This can be a sign of uncontrolled diabetes, poor dietary habits, or an inadequate treatment plan.
Common causes of high Hemoglobin A1c levels include:
To manage high Hemoglobin A1c levels, the following actions can help:
Low Hemoglobin A1c levels are less common but can indicate certain health issues or even over-treatment in individuals with diabetes.
Common causes of low Hemoglobin A1c levels include:
To manage low Hemoglobin A1c levels, consider the following steps:
If you have abnormal Hemoglobin A1c levels, it’s essential to seek medical advice to understand the underlying causes and develop an effective treatment plan. The specialists you may need to consult include:
Hemoglobin A1c is a blood marker that shows average blood sugar levels over the past two to three months.
You can lower hemoglobin A1c by eating a balanced diet, exercising regularly, reducing stress, and following your doctor's treatment plan.
In a blood test, hemoglobin A1c measures the percentage of hemoglobin bound to glucose, indicating long-term blood sugar control.
