What's this test for?

This test is ideal if you're experiencing symptoms like excessive thirst, frequent urination, fatigue, or blurry vision that could point to diabetes or prediabetes. It's also a good option if you have a family history of diabetes or your routine screening showed a borderline blood sugar reading. The test tracks how your body handles sugar over time, giving a clearer picture than a single blood draw.

What happens after I get my results?

Your results will be available in your account, with each glucose reading shown next to its normal range so you can see exactly where you stand at each time point. If your levels come back high, simple next steps include cutting back on refined carbs and sugary drinks, adding more movement to your day, and retesting in a few months to track changes. If any reading is extremely high, seek medical care right away since that can signal a more urgent problem. You can download the full lab report from your account anytime, and the trends feature lets you compare this test to future ones to see how your blood sugar handling changes over time.

What symptoms indicate I may need this test?

Common signs include feeling unusually thirsty, needing to urinate more often, feeling tired even after resting, and noticing blurry vision. Unexplained weight loss, slow-healing cuts, or tingling in your hands and feet can also be warning signs. If you've had a borderline blood sugar result before or have a close relative with diabetes, it's worth checking even without obvious symptoms.

How can I naturally support healthy blood sugar?
Eating more fiber-rich foods like vegetables, beans, and whole grains helps slow down sugar absorption into your blood. Regular walking or exercise, especially after meals, helps your muscles use up sugar more efficiently. Cutting back on sugary drinks and refined snacks, staying hydrated, and getting consistent sleep all help keep your blood sugar steadier throughout the day.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. Because this test involves multiple blood draws over a few hours, the lab needs a little extra time to process all six specimens together. You'll get a notification as soon as your results are posted to your account.
Who should consider this test?
This test is a good fit for anyone with symptoms of high blood sugar, a family history of diabetes, or a previous borderline glucose result. It's also useful for people who've been told they're at risk for diabetes due to weight, age, or lifestyle factors. Non-pregnant adults and children are appropriate candidates; pregnant women should ask about the separate pregnancy-specific glucose test instead.
What is glucose tolerance testing and why does it matter?
This test measures how well your body clears sugar from your blood after you drink a glucose solution, with blood drawn at several set time points. It matters because it can catch diabetes or prediabetes even when a single fasting blood sugar looks normal. Catching high blood sugar early gives you a chance to make changes before it leads to more serious health problems.
What does a high glucose result mean?
A glucose reading above 200 mg/dL at the 2-hour mark, along with a similarly high reading at another time point, suggests your body isn't clearing sugar from your blood as well as it should, which is a sign of diabetes. This happens when your body doesn't make enough insulin or doesn't use insulin effectively. If your results are high, cutting added sugars, increasing physical activity, and losing excess weight if applicable are practical starting points, along with retesting to confirm the trend.
What causes high glucose levels?
High glucose levels are usually caused by your body either not producing enough insulin or not responding to insulin properly, both of which are hallmarks of diabetes. Being overweight, eating a diet high in sugar and refined carbs, lack of physical activity, and genetics all raise your risk. Certain medications and other health conditions can also push glucose levels higher.
How often should I retest?
If your results are normal but you have risk factors like family history or excess weight, retesting every 1-3 years is a reasonable interval. If your results were borderline or high, retesting in 3-6 months after making lifestyle changes can help you see if those changes are working. Your results report will also give guidance based on your specific numbers.

Demo results
Glucose (2-hour specimen) 165 mg/dL
Demo results
Normal (<140 mg/dL) Prediabetes (140-199 mg/dL) Diabetes (200+ mg/dL)
165 mg/dL

What this means

A 2-hour glucose level of 165 mg/dL falls into the prediabetes range, meaning your body is having some trouble clearing sugar from your blood but hasn't reached diabetic levels yet. This is a good warning sign to make changes now before it progresses further.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
