Your Doctor Says Your Thyroid Is Fine.
Your Body Disagrees.
We test more than TSH — because subclinical thyroid dysfunction hides in the markers your annual physical doesn't check.
When "Normal" Thyroid Labs Don't Tell the Full Story
This is one of the most frustrating patterns in conventional medicine. You have textbook thyroid symptoms — fatigue, weight gain, hair thinning, brain fog, cold hands and feet, constipation — but your TSH comes back "normal" and you're told nothing is wrong.
The problem is that TSH alone doesn't tell the full thyroid story. TSH is a signal from the brain asking the thyroid to work. Free T3 and Free T4 are the actual hormones your body uses. You can have a "normal" TSH while your Free T3 is low — meaning your thyroid is being asked to work, but isn't producing enough active hormone.
Why We Test More Than Just TSH
Our functional bloodwork panel includes TSH, T3, and T4 — the minimum needed to properly evaluate thyroid function. We also assess these markers against optimal functional ranges, not just broad conventional ranges.
A TSH of 3.5 is "normal" conventionally but may indicate early hypothyroidism functionally. A low Free T3 with normal TSH points to a conversion problem — the thyroid is making T4 but not converting it to the active T3 form. These distinctions matter enormously for patients with thyroid symptoms.
Signs of Thyroid Dysfunction
Common signs that warrant thyroid investigation include persistent fatigue despite adequate sleep, unexplained weight gain or inability to lose weight, hair thinning or loss, brain fog and difficulty concentrating, feeling cold when others are comfortable, constipation and slow digestion, dry skin and brittle nails, depression or low mood, and irregular menstrual cycles in women.
If you recognize multiple symptoms on this list and your conventional labs have come back "normal," a functional thyroid panel may reveal what's been missed.
How We Support Thyroid Health
Treatment depends on findings. Your doctor may recommend targeted thyroid-supportive supplements (selenium, zinc, iodine, ashwagandha — specific to your results), dietary changes to reduce thyroid-disrupting inflammation, stress management strategies (cortisol directly affects thyroid conversion), and coordination with your primary care provider if medication is warranted.
Our goal is to optimize thyroid function naturally where possible — and to provide your PCP with detailed data if pharmaceutical intervention is needed.
Re-testing every 3–4 months through our hormone testing panel tracks whether your thyroid is responding.
Frequently Asked Questions
Why does my doctor say my thyroid is fine but I still feel off?
Most likely because only TSH was tested, and it fell within the broad conventional range. T3 and T4 — the hormones your body actually uses — may tell a different story. We test all three.
What thyroid markers do you test?
TSH, T3, and T4. All are included in our $299 panel.
Can diet and supplements help thyroid function?
In many cases, yes. Specific nutrients support thyroid hormone production and conversion, and reducing inflammation through diet can improve thyroid performance. The approach depends on your bloodwork results.
How often should thyroid levels be rechecked?
Every 3–4 months when actively working on thyroid optimization. Once stable, every 6–12 months for maintenance monitoring.
