What's this test for?

This test is ideal if you're pregnant and your provider has flagged a need to check how your body handles sugar after eating. It measures your blood sugar one hour after drinking a glucose solution to screen for gestational diabetes. It's also useful if you've had risk factors like excess weight gain, a family history of diabetes, or a previous high-birth-weight baby.

What happens after I get my results?

Your glucose result will appear in your account along with the normal range so you can see exactly where you fall. If your number comes back high, the next step is usually a longer 3-hour glucose tolerance test to confirm gestational diabetes, so don't panic at a single elevated reading. In the meantime, simple steps like reducing sugary drinks and refined carbs, walking after meals, and spacing out meals can help support healthy blood sugar. You can download a standard lab report from your account anytime, and if you retest later in pregnancy, the trends feature lets you track changes over time.

What is glucose and why does it matter?

Glucose is the sugar your body uses for energy, and it comes mainly from the carbs you eat. During pregnancy, hormones can make it harder for your body to manage blood sugar properly, which is why this test checks how well your body clears sugar after a meal. Keeping glucose in a healthy range matters because consistently high levels during pregnancy can affect both you and your baby.

How can I naturally support healthy blood sugar?
Eating balanced meals with protein, fiber, and healthy fats instead of just carbs can help keep blood sugar steadier. A short walk after meals is one of the simplest ways to lower post-meal glucose spikes. Cutting back on sugary drinks, juice, and refined snacks also makes a noticeable difference. Staying hydrated and getting regular sleep support overall blood sugar balance too.
When will I get my results?
Results are typically ready within about 7 days of your blood draw. You'll be notified as soon as your report is available in your account, so you can check your glucose level and see how it compares to the normal range without waiting for a phone call.
Who should consider this test?
This test is a good fit for pregnant women, especially those between 24 and 28 weeks along, since this is the typical window for gestational diabetes screening. It's also worth considering if you have risk factors like being overweight, having polycystic ovary syndrome, or having had gestational diabetes in a previous pregnancy. Anyone advised to check post-meal blood sugar levels can also use this test.
What symptoms indicate I may need this test?
Increased thirst, needing to urinate more often than usual, unusual fatigue, or blurry vision during pregnancy can sometimes point to blood sugar issues worth checking. Many people with gestational diabetes have no symptoms at all, which is why routine screening during pregnancy is so common. If you notice sudden changes in energy or appetite, it's reasonable to get your glucose checked.
What does a high glucose result mean?
A high result after this 1-hour test suggests your body may not be processing sugar as efficiently as expected, which can be a sign of gestational diabetes. It doesn't mean you definitely have it — a follow-up 3-hour test is used to confirm the diagnosis. In the meantime, cutting back on added sugars and refined carbs and adding light activity like walking can help support your levels.
What causes a high glucose result?
During pregnancy, hormones from the placenta can make your cells less responsive to insulin, causing blood sugar to rise more than usual after eating. Eating a large amount of sugar or refined carbs right before the test, certain medications, or an underlying tendency toward insulin resistance can also push the number higher. Stress and lack of sleep can play a smaller role as well.
How often should I retest?
If your first result is high, you'll typically move on to the 3-hour confirmation test fairly soon after. If your levels are normal but you have risk factors, your care plan may include rechecking later in pregnancy, often around 24-28 weeks if you haven't been tested yet. Tracking results over time in your account can help you and your care team spot any changes early.

Demo results
Glucose (1-Hour Postprandial) 148 mg/dL
Demo results
Normal (<140 mg/dL) Borderline (140-199 mg/dL) High (200+ mg/dL)
148 mg/dL

What this means

A result of 148 mg/dL is above the typical cutoff of 140 mg/dL, which means a follow-up 3-hour glucose tolerance test is usually recommended to confirm gestational diabetes. One elevated reading doesn't confirm a diagnosis on its own. Lifestyle habits and confirmatory testing will help clarify what's going on.

* 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.
