Hemoglobin A1c (HbA1c) with eAG with Reflex to 1,5-Anhydroglucitol (1,5-AG)
Your average blood sugar over the past three months, the core marker for diabetes risk and control.
Consider this test if:
- Family history of diabetes or a personal history of prediabetes
- Tracking whether diet, exercise, weight loss, or medication is improving glucose control
- Symptoms like increased thirst, frequent urination, fatigue, or blurred vision
- Establishing a metabolic baseline alongside routine cardiovascular and weight goals
- Managing diagnosed diabetes and monitoring control every few months
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Reflex testing
If your A1c falls outside the standard range, a 1,5-anhydroglucitol (1,5-AG) test runs automatically to reflect shorter-term glucose swings that A1c can miss. This follow-up is done at no additional cost.
Pre-test considerations
No fasting required. A1c reflects a three-month average, so timing of day and recent meals do not affect it. If you have anemia, a hemoglobin variant, or recent blood loss or transfusion, mention it, since these can skew the result.

What this test is for
Hemoglobin A1c reflects the percentage of hemoglobin coated with glucose, which tracks your average blood sugar over roughly the previous three months. This version also reports estimated average glucose (eAG) in mg/dL and mmol/L, translating the percentage into the same units as a home glucose meter. Rising A1c signals prediabetes or diabetes and is the standard marker for both screening and tracking glucose control over time; the ADA suggests testing twice a year with stable glucose and quarterly when control is poor. A1c can be distorted by conditions that change red-blood-cell lifespan, such as anemia, recent blood loss, or hemoglobin variants, so an unexpected result is worth confirming.
This is the standard A1c with eAG. The plain Hemoglobin A1c item reports the percentage alone, while the Glycomark variant reflexes to a different follow-up marker for short-term glucose swings.
Biomarkers tested

- Specimen
- Whole blood
- Method
- Estimated from HbA1c
- Measures
- Mass concentration
HbA1c measures the fraction of hemoglobin that glucose has permanently attached to over the roughly three-month lifespan of a red blood cell, giving you an average blood sugar reading rather than a single-moment snapshot. Elevated levels point to prediabetes or diabetes and reflect cumulative glucose exposure that drives vascular damage, so it's a core piece of cardiovascular and metabolic risk assessment even before symptoms appear. It also pairs well with fasting insulin and glucose to track how diet, training, weight loss, or medication are actually changing your metabolic trajectory over time.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost — covering the lab and what it takes to run the service — never a profit on the test itself; Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9/mo, and you still pay the lab’s order fee. Prices are itemized before you pay, with no hidden fees.
Where do I get tested?
Choose a partner lab (Quest, Labcorp, or BioReference) at checkout. If your cart spans multiple tests, we consolidate the whole order onto a single lab so you only make one visit.
Is this eligible for HSA/FSA?
Yes. This test is HSA/FSA eligible, and you can pay with your HSA/FSA card at checkout.
When will I get my results?
Your results post to your dashboard once your lab completes them, then a clinician reviews them and your full analysis and personalized action plan (with clear next steps) follow. Turnaround varies by test: specialty assays and at-home kits take longer, and each test shows its expected turnaround before you buy.
Do I need a doctor’s order?
No. Mito provides the lab order for you, so you can book and get tested without a separate doctor visit.
