Also Known As
A1C Test, HbA1C, Hgba1c, Hgb a1c, and Glycated Hemoglobin Test.
What Is the Purpose of the Hemoglobin A1c Test
An A1c test measures your average blood sugar levels over the last three months. It’s used to help diagnose prediabetes as well as type 1 or type 2 diabetes. People who already have diabetes al
so use an A1c blood test to monitor their levels to ensure their blood sugar is under control.
What Does the A1c Test Measure?
The results measure the percentage of hemoglobin proteins in your red blood cells that have sugar (also called glycated hemoglobin). Red blood cells typically live for three months before they die and are replaced by new cells. By measuring the amount of hemoglobin A1c, you will get an average of what your blood sugar has been over that period of time.
Who Should Take an A1c Blood Test?
If you have diabetes, your doctor may suggest a regular testing schedule to make sure your treatment plan is working or needs modification. You may also choose to track your blood sugar levels on your own with an A1c lab test a couple of times a year.
Hemoglobin A1c tests can also be employed to help diagnose diabetes, especially if you have risk factors for the disease. Type 1 diabetes risk factors include a family history of the disease or age (onset is predominantly among kids, teens, and younger adults). Type 2 diabetes risk factors include unhealthy weight, sedentary lifestyle, family history, prediabetes, and age (45 or older).
Hemoglobin A1c Test Preparation
No special preparation is necessary.
Hemoglobin A1c Lab Test Results
Your hemoglobin A1c blood test result is entered as a percentage, and can include another number that reflects your Estimated Average Glucose in mg/dL.
For diagnosing the disease, the Centers for Disease Control and Prevention offers the following guidelines:
Normal A1c percentage: Below 5.7%
Prediabetes: 5.7% to 6.4%
Diabetes: 6.5% or higher
For someone who is diabetic, A1c results should be less than 7%, or the percentage that has been recommended by their physician. Typically, higher A1c test results lead to an increased risk of diabetes complications.
A1c Testing for GLP-1 Medications (Ozempic, Wegovy, Mounjaro)
If you’re starting or currently taking a GLP-1 medication like Ozempic, Wegovy, Mounjaro, or Zepbound, a Hemoglobin A1c test is one of the most important labs you can get. Here’s why:
Before starting GLP-1 therapy: Most providers want to see a baseline A1c to confirm diabetes or prediabetes, assess your starting blood sugar control, and determine the right dosage. Some prescribers require it before writing the prescription.
While on GLP-1 therapy: Tracking your A1c every 3–6 months shows whether the medication is actually lowering your blood sugar and by how much. It’s the clearest measure of whether your treatment is working.
If you’re self-pay or using telehealth: Many GLP-1 telehealth providers require recent lab results including an A1c. Ordering through Personalabs at $50 is significantly cheaper than going through a traditional doctor’s office just to get the lab order.

FAQs About the Hemoglobin A1c Blood Test
Can I order an A1c blood test without a doctor?
Yes — in most states. Personalabs provides a physician-approved lab order as part of your purchase, so you don’t need your own doctor’s referral. Our network physician approves your order within 2–4 hours of purchase. A small number of states restrict direct-to-consumer testing; contact us to confirm availability in your state.
Do I need to fast before an A1c blood test?
No. Unlike a fasting glucose test, the A1c measures your 3-month average blood sugar, so what you eat or drink before the draw doesn’t affect the result. You can eat and drink normally before your appointment.
How much does an A1c blood test cost at Personalabs?
A Hemoglobin A1c test at Personalabs costs $50, with the physician lab order included. No insurance is required and there are no hidden fees. Your A1c is HSA and FSA eligible.
What A1c level indicates diabetes?
According to the CDC: below 5.7% is normal, 5.7%–6.4% is prediabetes, and 6.5% or higher indicates diabetes. For people already managing diabetes, most providers target an A1c below 7%, though your personal target may differ based on your treatment plan.
How often should I get an A1c test?
If you have diabetes, most providers recommend testing every 3 months to monitor blood sugar control. If you’re prediabetic or have risk factors, once or twice a year is typical. If you’re starting a GLP-1 medication like Ozempic or Wegovy, getting a baseline A1c before you start — and then retesting every 3–6 months — gives you the clearest picture of how the medication is working.
How does the A1c test differ from a fasting glucose test?
A fasting glucose test is a snapshot — it measures your blood sugar at one specific moment. The A1c gives you the 3-month average, which is much harder to game and gives providers a more reliable picture of long-term blood sugar control. For diagnosing diabetes, A1c is generally preferred because it doesn’t require fasting and captures trends over time.
What factors can affect A1c test results?
Anemia, certain blood disorders, kidney disease, recent blood loss, and blood transfusions can all affect A1c accuracy. Some people of certain ethnic backgrounds also have genetic hemoglobin variants that can skew results. If you have any of these conditions, mention them when reviewing results with your provider.
Can lifestyle changes lower my A1c?
Yes — significantly. Consistent exercise, reducing refined carbohydrates and sugar, maintaining a healthy weight, and managing stress can all lower A1c levels within one to three months. Many people with prediabetes reverse it entirely through lifestyle changes, which is exactly why early testing matters.
