Lab Testing & Biomarkers: Hormone Panels, Metabolic Labs & Optimal Ranges
The tests your doctor doesn't run — and why they matter
Standard bloodwork misses the early warning signs. Comprehensive panels with functional optimal ranges — not just 'normal' ranges — reveal the metabolic and hormonal dysfunction behind your symptoms.
The gap between 'normal' and 'optimal' lab ranges is where most people suffer. A fasting insulin of 20 μIU/mL is technically 'normal' (reference range: 2.6-24.9) but clinically indicates significant insulin resistance. A TSH of 4.0 is 'within range' but may represent subclinical hypothyroidism with real symptoms.
Our testing philosophy uses functional optimal ranges based on clinical research — tighter ranges where symptoms and disease risk are minimal — rather than statistical reference ranges derived from a broadly unhealthy population.
Why Standard Ranges Aren't Enough
'Normal' lab ranges are statistical constructs — they represent the middle 95% of the population tested at that lab. Since the average American has insulin resistance, is overweight, and is metabolically unhealthy, 'normal' ranges include a lot of dysfunction. Functional optimal ranges are based on clinical outcomes research: at what level do symptoms disappear and disease risk minimize?
Examples of the gap:
- Fasting insulin: 'normal' <25 μIU/mL → optimal <7 μIU/mL
- TSH: 'normal' 0.5-4.5 mIU/L → optimal 0.5-2.0 mIU/L
- Ferritin: 'normal' 12-300 ng/mL (men) → optimal 50-150 ng/mL
- Vitamin D: 'normal' 30-100 ng/mL → optimal 50-80 ng/mL
- Free T3: 'normal' 2.0-4.4 pg/mL → optimal 3.0-4.0 pg/mL
Our Core Lab Panels
Metabolic Panel: Fasting insulin, fasting glucose, HbA1c, HOMA-IR, comprehensive metabolic panel, lipid panel with particle size, hs-CRP, uric acid, homocysteine.
Hormone Panel (Men): Total testosterone, free testosterone, SHBG, estradiol, LH, FSH, DHEA-S, prolactin, PSA.
Hormone Panel (Women): Estradiol, progesterone, total testosterone, free testosterone, SHBG, DHEA-S, LH, FSH (cycle-day specific timing).
Thyroid Panel: TSH, free T3, free T4, reverse T3, TPO antibodies, thyroglobulin antibodies.
Recovery Panel: AM cortisol (or 4-point salivary), iron/ferritin/TIBC, vitamin D, magnesium (RBC), B12/folate, complete blood count.
Frequently Asked Questions
How much does comprehensive lab testing cost?
Our Comprehensive Analysis ($499) includes a full panel of 15-25 biomarkers, clinician interpretation, and a personalized protocol. Many individual tests are covered by insurance with CPT codes, and we provide a requisition form you can take to Quest or LabCorp. HSA/FSA funds are eligible.
Can I use my own lab results?
Yes. If you have recent bloodwork (within 3 months), we can review your existing results using our functional optimal ranges. However, most people find their standard panels are missing key markers like fasting insulin, free testosterone, free T3, or cortisol that we'd recommend adding.
How often should I retest?
We recommend a full retest 8-12 weeks after starting a new protocol, then quarterly for the first year, then biannually once results are stable. Some markers (like iron/ferritin during supplementation) may need more frequent monitoring.
