Can I order this test on its own?

Most labs can be ordered on their own with the “Lab Only” option, which includes a general results review. If you’d like your results personally reviewed — with a written Root Cause Report and personalized 12-week protocol — explore the 12-Week Program. Either way, add Tiffeny Parker as your practitioner when you register your kit so I can see your results.

Is this a medical diagnosis?

No. Functional lab testing is educational and is used to guide nutrition, lifestyle, and supplement strategy. It does not diagnose, treat, or cure any disease. Always work with your licensed healthcare provider for medical concerns.

How long do results take?

Most kits are collected at home in a single day and returned by prepaid mail. Results typically take about 2–4 weeks, depending on the panel.

Thyroid Panel Test

Also known as: TSH, T3, T4 & TPO antibodies

More than TSH — the full thyroid pathway, including antibodies.

How to get this lab ↓

Routine checkups often test only TSH. You can have a 'normal' TSH and still struggle to convert T4 into the active T3 your cells need — or have early autoimmune activity years before TSH changes.

What it measures

Thyroid Hormones

TSHThe brain's signal telling the thyroid to release hormones.
T4 / thyroxineThe thyroid's main output, needed to make T3.
T3 / triiodothyronineThe active hormone for metabolism, digestion, and bone health.

Autoimmunity

TPO antibodiesAn early sign of immune activity against the thyroid.

Who this is for

For classic "slow thyroid" symptoms — especially if you've been told your thyroid is fine based on TSH alone.

Fatigue
Feeling cold
Weight gain
Hair thinning or outer-eyebrow loss
Constipation
Dry skin
Brain fog
Low mood

How we interpret it

We read every panel through a functional lens — optimal reference ranges, ratios, and cross-panel patterns. Results become part of your written Root Cause Report and your personalized 12-week protocol.

Selenium, zinc, and iodine are essential for making and converting thyroid hormone, and your HTMA calcium/potassium ratio shows thyroid activity at the tissue level — so we read both together.

Often paired with

Minerals & Metals Test

Cellular mineral status and heavy metal burden — the foundation of the Method.

Stress, Mood & Metabolism Test

Sex hormones, cortisol, full thyroid, blood sugar, and vitamin D — the complete hormone picture.

Thyroid TSH Test

The brain's signal to the thyroid — a quick screen.

Common questions

Not sure which panels you need?

Start with the Root-Cause Fit Assessment. Takes about 3–5 minutes. If it looks like we're a good fit, you'll be invited to schedule a 45-minute consultation to discuss your health history, goals, and whether this program is the right next step for you.
