About this test
This panel measures fasting insulin and C-peptide, the two products your pancreatic beta cells release together when glucose rises, and combines them into a calculated insulin resistance score. Insulin resistance develops well before fasting glucose or A1c move, so this score often reveals a metabolic problem while standard glucose testing still reads normal. Elevated values point to the early insulin resistance behind prediabetes, type 2 diabetes, PCOS, fatty liver, and the weight gain, energy swings, and sugar cravings that often accompany them. Because insulin and C-peptide differ in half-life and clearance, using both together is a more reliable indicator of resistance than either alone.
The single-analyte C-Peptide and Insulin, Intact tests in our catalog report one marker each; this panel is the right choice when you want the combined resistance score rather than an isolated value.
Consider it if
- Normal glucose or A1c but a family history of type 2 diabetes or metabolic syndrome
- Weight gain around the midsection, sugar cravings, or energy crashes after meals
- PCOS, fatty liver, or other conditions tied to insulin resistance
- Setting a metabolic baseline before changing diet, training, or starting a medication
- Tracking whether weight loss, low-carb eating, or exercise is improving insulin sensitivity
Why are there member and non-member prices?
Members get Mito's no-markup price on tests. The non-member price is the standard price.
Mito membership is $9/month and unlocks member pricing across the catalog. It's how Mito is supported, so we don't have to mark up your tests or earn more when you buy more. Your member savings are applied at checkout.

Pre-test considerations
Overnight fasting is required: water only for 8 to 12 hours before the draw. Schedule a morning blood draw and keep diet and activity typical in the days beforehand. If you take insulin or insulin-affecting medications such as metformin or a GLP-1 drug, note the dose and timing, since they influence the result.

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. Your price is our cost plus a small amount 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. Members pay even less, applied at checkout (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 are typically visible within 1-2 business days of your lab visit. A clinician then reviews them, and your full analysis and personalized action plan — with clear next steps — follow once that review is complete. Specialty assays and at-home kits take longer; each test shows its 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.
