Functional Medicine
Advanced Lab Testing
Your doctor ran a basic metabolic panel and a CBC. Maybe a TSH. That covers about 15 markers. We run over 100. The difference between a basic panel and a complete one is the difference between guessing and knowing.
What Standard Labs Miss
You go to your annual physical. They draw blood. A week later, you get a call or a message: "Everything looks normal." But you don't feel normal. You're tired all the time. The weight won't budge. Your brain feels foggy. Your sleep is broken. Your joints ache. And your doctor says the labs are fine.
Here's what actually happened. Your doctor ran a CBC (complete blood count) and a basic metabolic panel. Maybe a lipid panel for cholesterol. If you're lucky, they added a TSH for your thyroid. That's roughly 15 markers. It's a screening. It tells your doctor whether you have an acute illness right now. It does not tell anyone whether your body is functioning well.
What a standard thyroid check looks like: TSH. That's it. One number. TSH is a signaling hormone from your brain. It tells your thyroid to produce T4 and T3, the hormones that actually run your metabolism, energy, and temperature regulation. But your doctor doesn't check T3 or T4. They don't check reverse T3, which can block your active thyroid hormone. They don't check thyroid antibodies, which would tell you if Hashimoto's (autoimmune thyroid disease) is destroying your thyroid. They check one signal and call it a complete picture.
Why they don't test more. It's not because the tests don't exist. It's because the medications they prescribe only require monitoring one marker. If the treatment is levothyroxine (synthetic T4), the only number they care about is TSH. As long as that looks normal, they consider you treated. It doesn't matter that you still feel exhausted, still gaining weight, still losing hair. The lab number fits the medication algorithm. That's where it ends.
The same pattern plays out with every system. Hormones? They might check total testosterone if you beg, but not free testosterone, estrogen, progesterone, DHEA, prolactin, or cortisol. Inflammation? CRP and ESR are simple blood tests, but they're rarely included on a standard panel. Nutrient levels? Vitamin D, B12, ferritin, magnesium, zinc. All easy to test. Almost never tested. Insulin? Your doctor checks fasting glucose. But fasting insulin, which catches insulin resistance years before diabetes develops, is almost never ordered.
This isn't an accident. Insurance-based care is designed to match a test to a medication. If the medication doesn't require the test, the test doesn't get ordered. The result is that millions of people walk around feeling terrible with "normal" labs.
“Most providers are running labs based on the medications they can give. If your medication only requires monitoring TSH, they don't care what the rest of the thyroid panel looks like.”

What We Test
Your first visit at Med Matrix includes a blood draw of roughly 100 biomarkers plus an InBody 770 body composition scan. This is the most thorough snapshot of your health most patients have ever received. Here's what's on the panel.
Full thyroid panel:
- TSH (the signal)
- Free T4 and Total T4 (the inactive thyroid hormone)
- Free T3 (the active thyroid hormone that runs your metabolism)
- Reverse T3 (can block T3 from working)
- Thyroid peroxidase antibodies and thyroglobulin antibodies (Hashimoto's screening)
Sex hormones:
- Testosterone (total and free), estrogen (estradiol), progesterone, DHEA, prolactin
Metabolic health:
- Fasting insulin (catches insulin resistance before it becomes diabetes)
- Fasting glucose and HbA1c
- Full lipid panel (cholesterol, triglycerides, LDL, HDL)
Inflammatory markers:
- CRP (C-reactive protein) and ESR (erythrocyte sedimentation rate)
Nutrient levels:
- Vitamin D, B12, ferritin (iron storage), magnesium, zinc
Additional markers:
- Cortisol, CBC, liver and kidney function, cardiac risk markers
Body composition:
- InBody 770 scan: lean mass, body fat percentage, visceral fat, hydration levels, basal metabolic rate
When deeper investigation is needed, we also use the DUTCH test (dried urine test for hormones). This measures hormone metabolites at the tissue level, showing how your body is processing and using hormones, not just what's floating in your blood. It's the gold standard for managing ongoing hormone therapy. We also offer advanced stool testing for gut microbiome and immune health.
All of this data goes to your provider before your first visit. When you sit down together, they already have the full picture.

Data without action is just numbers on a page. At Med Matrix, every result connects to a decision.
Here are real examples of what we find and what we do about it:
Hashimoto's that nobody tested for. Laura came to Med Matrix wanting to get off pharmaceuticals. She had high cholesterol, thyroid issues, and persistent fatigue. She'd asked her primary care to test her for Hashimoto's. They refused. Her first lab review at Med Matrix revealed Hashimoto's disease, plain as day. She transitioned to natural thyroid support and targeted supplements. The fatigue lifted. She felt better than she had in years.
Insulin resistance hiding behind "normal" glucose. Your fasting glucose can look fine while your fasting insulin is through the roof. That means your pancreas is working overtime to keep glucose in range, but the system is already failing. Catching this early, before your A1C crosses the diabetes threshold, lets us reverse the process with dietary changes, lifestyle modifications, and sometimes GLP-1 medications. Waiting until you're pre-diabetic or diabetic means the damage is already done.
Suboptimal T3 on levothyroxine. Patients come in on synthetic T4 (levothyroxine or Synthroid) and their doctor says the thyroid is fine because TSH is normal. But when we check free T3, it's low. Their body isn't converting T4 to the active form efficiently. They're gaining weight, exhausted, and losing hair while being told everything is fine. Optimizing T3 with a different medication protocol frequently produces dramatic improvements in energy, weight, and mood.
Nutrient deficiencies driving symptoms. Low ferritin causes fatigue and hair loss. Low vitamin D increases inflammation and weakens immunity. Low magnesium disrupts sleep and muscle function. Low B12 causes brain fog and nerve issues. These are simple problems with simple fixes, but they have to be found first. Your doctor isn't testing for them.
One of our 7 providers reviews your complete panel, your health history, and your goals before your one-hour visit. You go through every result together. Nothing gets glossed over. You leave with a plan that addresses what your labs actually show, not a generic recommendation to eat better and exercise more.

Advanced Lab Testing FAQ
We test roughly 100 biomarkers including a full thyroid panel (TSH, free T3, free T4, reverse T3, thyroid antibodies), sex hormones (testosterone, estrogen, progesterone, DHEA, prolactin), fasting insulin, inflammatory markers (CRP, ESR), cortisol, vitamin D, B12, ferritin, magnesium, zinc, and a complete metabolic and cardiac risk panel. Your doctor likely checks about 15 markers. The difference is the difference between a screening and a diagnosis.
Providers in the conventional system run labs based on the medications they prescribe. If the only thyroid medication they offer is levothyroxine, the only number they need to monitor is TSH. There's no clinical reason (within their model) to check T3, reverse T3, or thyroid antibodies. Insurance reinforces this by covering only the tests that align with the treatment algorithm. It's not that your doctor doesn't care. It's that the system wasn't designed to look deeper.
The DUTCH test is a dried urine hormone panel that measures hormone metabolites in dried urine samples collected over a 24-hour period. It shows how your body is producing, processing, and eliminating hormones at the tissue level. Blood tests show what's circulating. The DUTCH test shows what's actually happening at the receptor. It's the gold standard for managing hormone therapy and is especially useful for patients already on bioidentical hormones who need precise adjustments.
Initial onboarding is about $1,200 to $1,500 all-in. That covers your 100-biomarker blood panel, InBody 770 body composition scan, provider prep time, and your full one-hour provider visit. Follow-up visits are $275. DUTCH testing and advanced stool testing are additional costs if your provider recommends them. We accept HSA, FSA, CareCredit, and all major cards. New patients receive a $100 voucher toward their first visit.
Absolutely. Your results are yours. Many patients share their Med Matrix lab results with their primary care physician. Laura, one of our patients, sent a copy of her lab work to her primary care after we discovered Hashimoto's that they had declined to test for. Having a complete panel often changes the conversation with your other providers because they're seeing data they never had before.
Reference ranges on standard lab work are based on population averages. They tell you whether you fall within the range of everyone else who was tested, including people who are unhealthy. 'Normal' on a lab report means you're not an extreme outlier. It doesn't mean your body is functioning well. Functional medicine uses tighter, evidence-based optimal ranges that reflect where your body performs best. A TSH of 4.0 is 'normal.' It's not optimal. A testosterone of 320 is 'in range.' It's not where most men feel good. We look at optimal, not just normal.
