Measures blood glucose levels to screen for diabetes and monitor blood sugar control. 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. **Clinical use:** Single fasting blood-glucose measurement. A snapshot of current blood sugar; pair with A1c for the full diabetes screening picture. ## Who should order it? 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). ## Biomarkers measured - [Glucose](https://www.test-well.com/biomarkers/glucose) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Labcorp | $14.99 | $20.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served. Prices are identical online and in the lab; no draw fee or physician fee is added. ## How much does a Glucose test cost? 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 | | --- | --- | --- | --- | | TestWell (drawn at Quest or Labcorp) | $14.99 | $20.99 | Includes the one $6 lab processing fee, charged once per order | | Hospital outpatient lab, self-pay (typical) | $50.00 | $50.00 | Reference figure; hospital charges vary widely by facility and are often higher | Lab test codes: Labcorp test no. 001032. ## How do you prepare? Fasting for 8–12 hours is required for an accurate result. Water is okay. ## Related conditions - [Type 2 diabetes](https://www.test-well.com/conditions/diabetes-screening) (E11.9) - [Prediabetes](https://www.test-well.com/conditions/diabetes-screening) (R73.03) - Hypoglycemia (E16.2) - Gestational diabetes (O24.4) ## Common questions about the Glucose test ### What's a normal fasting glucose? 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. ### Why fast for a glucose test? 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. ### What's the difference between fasting glucose and A1c? Fasting glucose is a snapshot of this morning's blood sugar; [A1c](https://www.test-well.com/tests/hemoglobin-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](https://www.test-well.com/tests/diabetes-screening-panel) bundles both plus insulin. ### How much does a fasting glucose test cost without insurance? 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. ### What is the CPT code for a fasting glucose test? 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. ### Should I order fasting glucose alone or with A1c? 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](https://www.test-well.com/tests/comprehensive-metabolic-panel) includes fasting glucose plus 13 other markers for nearly the same price. ### How often should I retest fasting glucose? 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. ## How to order 1.
