Glucose, Fasting and 2-Hour Postprandial
Two glucose readings, fasting and after a meal, showing both your baseline and how your body clears sugar.
Consider this test if:
- Fasting glucose has looked borderline or normal but you want to see post-meal spikes
- Family history of type 2 diabetes or a personal history of insulin resistance
- Symptoms like excess thirst, frequent urination, fatigue, or unexplained weight change
- Tracking whether diet, weight loss, or medication is improving glucose control
- Pregnant and screening for elevated post-meal glucose
- 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
The fasting sample requires 8 to 12 hours with no food or caloric drinks; water is fine. The second sample is drawn exactly two hours after the start of a meal, so time the meal carefully. Illness, physical stress, and some medications such as steroids can raise glucose temporarily.

What this test is for
This test measures blood glucose twice: once after an overnight fast and again two hours after a meal. The fasting value reflects your baseline glucose control, while the postprandial value shows how efficiently your body clears sugar after eating, which often rises before fasting glucose looks abnormal. Elevated readings point toward prediabetes, type 2 diabetes, insulin resistance, or, in pregnancy, gestational diabetes. A high two-hour result during pregnancy is usually confirmed with a formal oral glucose tolerance test.
This pairing uses your own meal rather than a standardized sugar drink. The separate Glucose Tolerance Test gives a fixed 75g glucose load for a controlled diagnostic challenge, and the standalone fasting or 2-hour tests measure just one of these two points.
Biomarkers tested
Includes 2 biomarkers
- Specimen
- Serum or plasma
- Measures
- Mass concentration
Fasting glucose measures how much sugar circulates in your blood after roughly eight hours without food, reflecting how well insulin manages the glucose your liver releases overnight. High readings point toward insulin resistance, prediabetes, or diabetes, while very low readings suggest your body is clearing glucose faster than it can be replenished. It's a core baseline for tracking metabolic health over time and pairs well with fasting insulin or A1c when investigating fatigue, weight gain, sugar cravings, or a family history of diabetes.

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.
