What this test screens for
Understanding the Glucose Blood
A Glucose Blood Test measures the amount of glucose (sugar) in your blood at the time of the draw. It is used for diabetes screening, pre-diabetes monitoring, and medication management. The test can be ordered as a fasting glucose (drawn after at least 8 hours without food) or as a random glucose (drawn at any time).
At our Ashburn lab, a glucose blood test is $59 and requires no doctor referral. Results post to your secure online portal within 24 to 72 hours. A fasting glucose is the standard for diabetes screening — the American Diabetes Association defines fasting glucose under 100 mg/dL as normal, 100 to 125 mg/dL as prediabetes, and 126 mg/dL or higher (confirmed on repeat) as indicative of diabetes.
For a more complete picture of blood sugar control over the past 2 to 3 months, pair the glucose test with an A1C ($89). Both are included in the Annual Check-Up Panel ($159) and the Comprehensive Wellness Panel ($279), which bundle core blood markers at a meaningful discount. If you are specifically tracking diabetes risk or progression, discuss testing frequency with a primary-care provider.

- Prediabetes monitoring and lifestyle-change tracking
- Medication management (checking glucose levels on metformin or other diabetes medications)
- Annual baseline labs as part of a routine health check
- Pre-surgical or pre-procedure labs
- Investigating symptoms such as excessive thirst, frequent urination, or fatigue
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
Fast 8 to 12 hours before the draw for a fasting glucose (plain water OK). Take morning medications normally unless your prescriber specifically says to hold them. If you need a random glucose (non-fasting), no preparation is needed — come in at any time.
During your visit
A single small blood draw — one tube, completed in under 5 minutes. Most clients are in and out of the lab in 10 minutes total from check-in to walking out. The draw is performed by a trained phlebotomist in a private collection room.
Getting your results
Results post to your secure online portal within 24 to 72 hours, along with the lab’s reference range. A single glucose reading is a snapshot — discuss your result with a primary-care provider, especially if it falls in the prediabetes range or above. Persistent elevated glucose typically warrants A1C testing and clinical evaluation.

FAQ
Glucose Blood Test — what people ask
Specific questions about the glucose blood test. For anything not covered, call 571-500-7030.
What is the difference between fasting glucose and random glucose?
Fasting glucose is drawn after at least 8 hours without food and is the standard for diagnosing prediabetes and diabetes. Random glucose can be drawn at any time; a result of 200 mg/dL or higher with symptoms may indicate diabetes. For the most useful result in a screening context, fasting is preferred.
Should I order glucose alone or pair it with A1C?
Glucose gives a snapshot at the moment of the draw. A1C shows the average blood sugar over the past 2 to 3 months — a more complete picture of long-term glucose control. Both are included in the Annual Check-Up Panel ($159), which is often the most cost-effective option for adults wanting a baseline blood sugar assessment.
If my fasting glucose is in the prediabetes range, what should I do?
A single prediabetes-range result (100 to 125 mg/dL) warrants confirmation on a repeat test and a conversation with a primary-care provider. Prediabetes is reversible with lifestyle changes — diet, exercise, and weight management — and many adults with prediabetes do not progress to type 2 diabetes with appropriate intervention.
