What's this test for?

This test is ideal if you're experiencing increased thirst, frequent urination, unexplained fatigue, or blurry vision that could point to blood sugar problems. It's also commonly used if you've had a high glucose reading before, have a family history of diabetes, or were told during pregnancy that you need to check how your body processes sugar. The test tracks how your blood sugar rises and falls after drinking a glucose solution, showing how well your body handles sugar over time.

What's included in this test?

This test measures your blood glucose at five separate points: a fasting baseline, then at set intervals after you drink a glucose solution. Looking at multiple time points instead of just one gives a much clearer picture of how efficiently your body processes and clears sugar from your blood, which a single reading can't show.

What happens after I get my results?

Your results will show up in your account, with each of the five glucose readings explained against its normal range so you can see how your body responded at each time point. If any value comes back high, simple next steps include cutting back on refined carbs and sugary drinks, increasing physical activity, and rechecking your levels within the timeframe suggested in your report. If a reading is dangerously high, especially the 2-hour result over 200 mg/dL, seek medical care promptly. You can download the full lab report anytime and use the trends feature to compare results if you test again in the future.

How can I naturally support healthy blood sugar levels?
Eating more fiber-rich foods like vegetables, beans, and whole grains helps slow down sugar absorption into your blood. Regular movement, even a 20-30 minute walk after meals, helps your muscles use up sugar more efficiently. Cutting back on sugary drinks, refined carbs, and late-night snacking also makes a noticeable difference, and getting consistent sleep helps keep your blood sugar hormones balanced.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. Once processed, they'll be uploaded directly to your online account, where you can view each of the five glucose measurements along with what they mean.
Who should consider this test?
This test is a good fit if you have symptoms of high blood sugar, a family history of diabetes, or previous borderline glucose results. It's also frequently recommended if you're pregnant and need to check for gestational diabetes, or if you're overweight and want to catch a blood sugar problem early, before it becomes diabetes.
What symptoms indicate I may need this test?
Common signs include feeling unusually thirsty, needing to urinate more often, feeling tired even after resting, blurry vision, or slow-healing cuts. Some people notice tingling in their hands or feet, or unexplained weight changes. If these symptoms sound familiar, this test can help clarify what's going on with your blood sugar.
What does a high glucose result mean?
A high reading, especially a 2-hour result over 200 mg/dL, suggests your body isn't clearing sugar from your blood as efficiently as it should, which is how diabetes is diagnosed. Values between normal and that threshold may point to prediabetes, an early stage where lifestyle changes can still make a big difference. In either case, cutting added sugar, increasing activity, and rechecking your levels are good first steps, with medical care recommended for very high or symptomatic results.
What causes abnormally high glucose tolerance results?
High results usually happen because the body either doesn't make enough insulin or doesn't respond to it well, so sugar lingers in the blood instead of moving into cells for energy. Being overweight, eating a lot of processed carbs and sugar, lack of physical activity, chronic stress, and certain medications can all make this worse. Genetics and family history also play a meaningful role in how your body handles sugar.
How often should I retest?
If your results are normal and you have no risk factors, retesting every 1-3 years is generally reasonable. If you were borderline or have risk factors like extra weight, family history, or prior gestational diabetes, retesting every 6-12 months helps catch changes early. Your lab report will include guidance based on your specific results.

165 mg/dL

What this means

A 2-hour glucose level of 165 mg/dL falls in the prediabetes range, meaning your body is having some trouble clearing sugar from your blood efficiently. This isn't diabetes yet, but it's a signal 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.
