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. Already have results? Analyze them with your AI assistant against our physician-reviewed ranges.
Fasting for 8–12 hours is required for an accurate result. Water is okay.
What can throw off this result
Physician-reviewed “Before your test” pages — what each factor does, for how long, and what to do about it.
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.
| Where you order | Price | One test, all-in | Notes |

| Hospital outpatient lab, self-pay (typical) | $50.00 | $50.00 | Reference figure; hospital charges vary widely by facility and are often higher |

Normal: 70-99 mg/dL. Prediabetes (impaired fasting glucose): 100-125 mg/dL. Diabetes: 126+ mg/dL on two separate fasting tests. Below 70 mg/dL is hypoglycemia and warrants evaluation, especially if symptomatic.
Eating spikes blood sugar for 2-4 hours. Fasting (8+ hours, water only) gives a clean baseline reading that reflects your body's overnight glucose regulation. Coffee, juice, sugar in tea, gum, and most medications break the fast.
Fasting glucose is a snapshot of this morning's blood sugar; A1c is your 3-month average. Both have value: glucose catches acute spikes and is what gets used to diagnose gestational diabetes. A1c catches chronic elevation. The Diabetes Panel bundles both plus insulin.
On TestWell, the basic Glucose test is $14.99 — one of the cheapest standalone labs we offer. Quest Direct lists the same test at $20, walk-in hospital labs typically bill $40-50 without insurance.
The CPT code for fasting blood glucose is 82947. Random (non-fasting) glucose is also 82947 — the CPT doesn't distinguish; the fasting state needs to be noted on the order.
For routine screening, A1c is better because you don't have to fast. Fasting glucose adds value when investigating active symptoms (thirst, frequent urination), pregnancy, or hypoglycemia. For complete metabolic screening, the CMP includes fasting glucose plus 13 other markers for nearly the same price.
Every 1-3 years for healthy adults 35+ (or earlier with risk factors). Every 3-6 months if you're prediabetic or actively managing diabetes. Daily home monitoring is separate — this is for diagnostic and treatment-monitoring purposes.
Yes. The Glucose test is the standard fasting blood sugar test — a single fasting plasma glucose used to screen for prediabetes and diabetes. It is also searched as fasting blood glucose test, diabetes screening blood test. On TestWell it is $14.99 at Labcorp — no doctor's visit or insurance required, results in 1–2 business days.
A blood sugar test costs $14.99 out of pocket at TestWell ($20.99 all-in with the $6 per-order lab processing fee) — it is sold here as the Glucose, with no doctor's visit or insurance required. Results in 1–2 business days.
Glucose test results are typically ready in 1–2 business days after your draw at Labcorp. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.
Peptides and GLP-1s, eating before the draw, alcohol and common medications can change a Glucose test result without anything being wrong. Peptides and GLP-1s can lower Glucose — expected treatment effect — A1c is the monitoring marker, not a reason to stop. Eating before the draw can raise Glucose — fast 8–12 hours; water only. Alcohol can shift Glucose — abstain the evening before a fasting glucose. Common medications can raise Glucose — note steroid use; A1c reflects the average. Each factor is covered on our physician-reviewed "Before your test" pages; when one applies, the fix is usually to remove it and retest.
Order the Glucose test online from TestWell for $14.99 (plus a $6 per-order lab processing fee) — no doctor's visit, referral or insurance needed. A licensed physician authorizes the order, then you walk into any Labcorp patient service center near you for the draw (the lab locator on our site lists the closest ones by ZIP code), and results arrive in 1–2 business days.
