A basic glucose test measures the amount of sugar (glucose) in your blood. It is one of the most commonly ordered blood tests and is used to screen for diabetes and prediabetes, monitor blood sugar control, and evaluate hypoglycemia. Fasting glucose levels above 100 mg/dL may indicate prediabetes, while levels above 126 mg/dL on two separate occasions are diagnostic of diabetes. This test is recommended as part of routine health screenings, especially for individuals with risk factors such as obesity, family history, or sedentary lifestyle.
Single fasting blood-glucose measurement. A snapshot of current blood sugar; pair with A1c for the full diabetes screening picture.
Annual screening for adults 35+, anyone with diabetes risk factors (family history, BMI >25, sedentary lifestyle), monitoring during pregnancy, anyone with classic symptoms (thirst, frequent urination, fatigue).

Your Glucose results will include values for each of the 1 biomarker tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 1–2 business days.
Typical reference range layout
Lab reports show where your value sits relative to established reference intervals—your physician interprets this in context for you.
Fasting for 8–12 hours is required for an accurate result. Water is okay.
A Glucose test costs $14.99 at TestWell — $20.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Hospital outpatient labs typically bill around $50.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.
