Insulin Resistance Panel with Score
Combines insulin and C-peptide into one score that flags insulin resistance years before glucose climbs.
Consider this test 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
- HSA/FSA eligible
- Typical results in about 8 days · Reviewed by a real clinician
Blood draw at 1,900+ lab locations nationwide
How to prepare
- Fast for at least 8 hours before your test.

What this test is for
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.
Biomarkers tested
Includes 3 biomarkers
C-peptide is released in equal amounts to insulin when the pancreas cleaves proinsulin, making it a cleaner gauge of how much insulin your own beta cells are producing (it does not get cleared by injected insulin, so it separates your body's output from any insulin you take). High levels alongside high glucose point to insulin resistance, where the pancreas is grinding out more and more insulin to keep blood sugar in range, often years before an A1c or fasting glucose looks abnormal. Low levels help distinguish type 1 from type 2 diabetes and investigate unexplained hypoglycemia, while tracking C-peptide over time shows whether diet, weight loss, or medication are actually easing the burden on your pancreas.

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. It is never a profit on the test itself. Mito makes its money on the membership, not on marking up your tests. Membership is $9 per month or $99 per year, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Mito's lab tests are HSA/FSA eligible, so you can pay with pre-tax dollars.
Add the test to your cart and select "Pay with HSA/FSA" at checkout. You'll finish on the secure checkout page of Flex, our HSA/FSA payments partner, and Flex emails you an itemized receipt from notifications@withflex.com for your records.
Most Mito tests are auto-substantiated, so you usually won't need a Letter of Medical Necessity. If your HSA/FSA administrator asks for more, contact us and we'll help.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
