Glucose Tolerance Test, 1-Hour Postprandial
A one-hour glucose reading that screens for blood sugar that spikes too high after eating, most often used in pregnancy.
Consider this test if:
- Pregnant and being screened for gestational diabetes
- A prior pregnancy involved gestational diabetes or a large birth-weight baby
- Family history of type 2 diabetes or known risk factors during pregnancy
- Following up on a borderline fasting glucose with a post-meal measurement
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
Timing is the critical detail: blood must be drawn exactly one hour after the meal or glucose drink, so coordinate the draw with your provider's instructions. Follow the specific prep your clinician gives for the load used. Recent illness, certain medications, and major changes in activity can shift the result.

What this test is for
This test measures blood glucose exactly one hour after a glucose load or meal, capturing how high your blood sugar climbs once carbohydrate hits the bloodstream. It is most commonly used as the first-step screen for gestational diabetes, where a high one-hour value flags impaired glucose handling that fasting glucose alone can miss. A positive result is a screen, not a diagnosis: in pregnancy it is confirmed with a longer oral glucose tolerance test before gestational diabetes is diagnosed.
This is the single one-hour draw. The related two-specimen and 2-hour tolerance tests add fasting and later timepoints for fuller characterization, and the dedicated gestational protocols use a standardized 75-gram or follow-up load for confirmation.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost — covering the lab and what it takes to run the service — never a profit on the test itself; Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9/mo, and you still pay the lab’s order fee. Prices are itemized before you pay, with no hidden fees.
Where do I get tested?
Choose a partner lab (Quest, Labcorp, or BioReference) at checkout. If your cart spans multiple tests, we consolidate the whole order onto a single lab so you only make one visit.
Is this eligible for HSA/FSA?
Yes. This test is HSA/FSA eligible, and you can pay with your HSA/FSA card at checkout.
When will I get my results?
Your results post to your dashboard once your lab completes them, then a clinician reviews them and your full analysis and personalized action plan (with clear next steps) follow. Turnaround varies by test: specialty assays and at-home kits take longer, and each test shows its expected turnaround before you buy.
Do I need a doctor’s order?
No. Mito provides the lab order for you, so you can book and get tested without a separate doctor visit.
