Biomarker Lab Testing & Analysis
Comprehensive testing that reveals what standard blood work misses
Data-Driven Metabolic Assessment
You can't fix what you don't measure. And standard blood work doesn't measure enough. At Duluth Metabolic, we run comprehensive biomarker panels that go far beyond what you get at a typical annual physical.
Your doctor checks basic metabolic function and screens for disease. We test for optimal function. There's a big difference between "not sick" and "actually healthy," and our testing identifies where your metabolism is underperforming so we can target it precisely.
This data drives every aspect of your personalized treatment plan. No guessing, no generic protocols. Just targeted intervention based on what your body actually needs.
What We Test
- Fasting glucose and fasting insulin with HOMA-IR calculation (the gold standard for insulin resistance)
- HbA1c for 3-month glucose average
- Complete lipid panel including triglyceride-to-HDL ratio (a better cardiovascular risk marker than LDL alone)
- Complete thyroid panel: TSH, free T3, free T4, reverse T3, thyroid antibodies
- Vitamin D (25-OH), B12, folate, and key nutrient levels
- Inflammatory markers: hs-CRP, homocysteine, ferritin
- Liver and kidney function panels
- Hormone panels: testosterone, estrogen, progesterone, cortisol, DHEA
- Metabolic markers: uric acid, fasting insulin, magnesium, iron studies
Why Standard Blood Work Isn't Enough
A standard annual physical typically checks a basic metabolic panel, CBC, and maybe lipids. Your doctor is looking for red flags: diabetes, kidney disease, anemia. If nothing is flagged, you're told everything looks normal.
But that testing doesn't include fasting insulin (the earliest marker of metabolic dysfunction), a complete thyroid panel (most doctors only run TSH), inflammatory markers, or hormone levels. It misses the subclinical issues that cause fatigue, weight gain, brain fog, and mood changes years before they progress to diagnosable disease.
We test what matters for metabolic health, and we interpret results using optimal ranges rather than the broad "normal" ranges that standard labs use.
How Testing Informs Treatment
Initial testing establishes your metabolic baseline and identifies specific dysfunctions. We use this data to design your personalized nutrition plan, fasting protocols, supplement strategy, and exercise prescription.
Follow-up testing every 8-12 weeks tracks your progress and lets us refine your protocol. You'll see the changes in your lab numbers, which is motivating and confirms that the interventions are working. This data-driven approach ensures we're always moving in the right direction.
What to Expect
Most testing requires a fasted state (8-12 hours). We provide detailed preparation instructions. Results are typically available within 3-5 business days.
During your results review session, we walk through each biomarker, explain what it reveals about your metabolic health, and outline how it influences your treatment plan. You'll leave with a clear understanding of your current metabolic state and a concrete plan for improvement.
No Insurance Gatekeeping
In the insurance system, the tests you get are determined by diagnosis codes and preauthorization requirements — not by what your provider thinks you need. Without a diabetes diagnosis, most insurers won't cover fasting insulin or CGM. Without documented symptoms, a full thyroid panel gets denied. The tests that catch metabolic dysfunction early are exactly the tests insurance is least likely to approve.
Our cash-pay model removes that barrier entirely. We order the tests that your metabolic health assessment calls for, period. No preauthorization, no appeals, no waiting. <a href="/resources/cash-pay-healthcare-model">Learn more about how our cash-pay model works</a> and why it means better testing for you.
Frequently Asked Questions
Can't I just get these tests from my regular doctor?
You can request some of them, but many doctors won't order fasting insulin, complete thyroid panels, or hormone testing without a specific diagnosis code. As a cash-pay clinic, we order whatever testing is clinically indicated without insurance gatekeeping.
How much does testing cost?
Testing costs vary based on the panels ordered. We use direct-to-lab pricing which is often less expensive than what you'd pay through insurance with copays and deductibles. We'll discuss costs upfront before ordering any tests.
How often will I need retesting?
We typically retest every 8-12 weeks during active treatment to track progress and adjust protocols. Once you've achieved your metabolic health goals, annual or semi-annual testing is usually sufficient for maintenance.
