Hemoglobin A1c is a simple blood test that shows your average blood sugar levels over the past two to three months. It’s a key marker used to screen for prediabetes, diagnose type 2 diabetes, and monitor how well blood sugar is being managed over time. Unlike a fasting glucose test, the A1c gives a broader picture of your metabolic health—without the need to fast.
If you’re looking to track your blood sugar or understand your risk for diabetes, you can order a Hemoglobin A1c test online through our secure platform—no clinic visit required.
Test Description
The HbA1c test, also known as the Hemoglobin A1c or A1c test, measures the percentage of hemoglobin in your red blood cells that has glucose attached to it. Since red blood cells live for about three months, the test reflects your average blood sugar levels over that time period. Unlike a single glucose reading, which can be affected by meals or stress, the HbA1c provides a long-term view of how well your blood sugar has been managed.
The HbA1c test is commonly used in people with type 1 or type 2 diabetes to evaluate their average blood sugar levels over the past two to three months. It reflects how much glucose has attached to hemoglobin in red blood cells over time. Unlike daily blood sugar checks, which capture short-term changes, the HbA1c offers a longer-term view of glucose control. This makes it a valuable tool for assessing how well diabetes is being managed overall. It is also used to help diagnose diabetes and identify people at risk, such as those with prediabetes.
Because it does not require fasting, the HbA1c is often more convenient than other blood sugar tests. It can detect changes in glucose regulation before symptoms appear and is considered a reliable tool for early diagnosis and ongoing monitoring.
Markers
- Hemoglobin A1c
Who Should Consider This Test?
- People with prediabetes: To track whether blood sugar levels are improving, stable, or progressing toward diabetes.
- People with type 1 or type 2 diabetes: To monitor long-term blood sugar control and guide treatment adjustments.
- People with risk factors for diabetes: Such as a family history, higher weight, sedentary lifestyle, or history of gestational diabetes.
- People with unexplained fatigue, frequent urination, or increased thirst: These may be signs of elevated blood sugar that the A1c test can help detect.
- Women with polycystic ovary syndrome (PCOS): Insulin resistance is common in PCOS, and the A1c can help assess metabolic impact.
- People on medications that affect blood sugar: Such as corticosteroids or antipsychotics, to evaluate unintended changes in glucose regulation.
- People undergoing annual metabolic screenings: As part of routine health checks, especially after age 45 or with other metabolic risk factors.
