What this test screens for
Understanding the Hemoglobin A1C
The Hemoglobin A1C test (also called HbA1c, glycated hemoglobin, or just "A1C") measures your average blood sugar level over the prior 2 to 3 months. It is widely used by clinicians for diabetes screening and ongoing monitoring — a single blood draw that captures a longer-term picture than a one-time glucose reading.
Walk in any day during open hours for a $59 A1C test at our Chantilly lab. No referral, no insurance, no fasting required (A1C is unaffected by what you ate that morning, which is one of the reasons it has largely replaced fasting glucose for routine screening). Results post to your secure online portal in 24 to 72 hours.
Common reference ranges used by US clinical labs: under 5.7% is generally considered normal, 5.7% to 6.4% is the prediabetes range, and 6.5% or higher is the threshold most physicians use when considering a diabetes diagnosis (a single A1C result is not a diagnosis on its own — a licensed provider interprets the result alongside other markers and your history). For clients already managing diabetes, most physicians target an A1C of 7% or below — but the right target depends on age, comorbidities, and treatment plan, so discuss your specific number with a primary-care or endocrinology provider.
Why people get this test
- Annual diabetes screening for adults 45 and older (or earlier with risk factors)
- Monitoring blood-sugar control on diabetes medication or insulin
- Tracking progress on diet, weight, or exercise changes targeting blood sugar
- Family history of type 2 diabetes
- Symptoms of high blood sugar — frequent urination, increased thirst, unexplained weight changes, fatigue
- Pre-pregnancy screening or workup for gestational diabetes risk
What to expect
From check-in to results — what your visit looks like
Most visits take under 15 minutes. Here’s the full arc, start to finish.
How to prepare
No fasting needed — eat normally before your visit. Take morning medications as usual. The only thing that meaningfully affects an A1C result is conditions that change red blood cell lifespan (recent blood loss, blood transfusion, certain anemias, pregnancy). Mention these at check-in so the lab can flag them.
During your visit
A single small blood draw — typically one tube, completed in under 5 minutes. Most clients are in and out of the lab in 10 to 15 minutes from walking in. The blood is processed at the same reference labs hospitals use, with the same reference ranges your physician expects.
Getting your results
A1C results post to your secure online portal in 24 to 72 hours, reported as a percentage. The report typically includes an "estimated average glucose" (eAG) value in mg/dL alongside the percentage — useful when comparing to your home glucose meter readings. We can fax results to any provider at no additional charge.

FAQ
Hemoglobin A1C Test — what people ask
Specific questions about the hemoglobin a1c test. For anything not covered, call 571-500-7030.
Do I need to fast for an A1C test?
No. A1C measures blood sugar averaged over the prior 2 to 3 months, so the meal you ate that morning has no effect on the result. This is one of the main reasons A1C has largely replaced fasting glucose for routine diabetes screening.
What is a normal A1C level?
Under 5.7% is generally considered normal. 5.7% to 6.4% is the prediabetes range — an indication that blood sugar is elevated but not yet at diabetes thresholds. 6.5% or higher is the threshold most physicians use when considering a diabetes diagnosis; the diagnosis itself is made by a licensed provider after reviewing results alongside other markers and your history. Treatment targets for diagnosed diabetes are usually 7% or lower, but your physician sets the right target for you.
How often should I re-test my A1C?
For adults with normal A1C and no risk factors, every 3 years is typical. For prediabetes, annually. For diagnosed diabetes, every 3 to 6 months — more often when medication or treatment is changing. The Comprehensive Wellness Panel ($279) includes A1C alongside lipid, thyroid, and other key markers in one draw.
