Diagnostics
Thyroid & Autoimmune
The full thyroid picture most tests skip, including autoimmune activity.
- Free physician review call included
- Drawn at an accredited lab near you
- You leave with a plan, not a PDF
Why it matters
Metabolic decline is quiet. Until it isn't.
Beyond TSH
Free hormones and antibodies tell the real story a single TSH can't.
Catch autoimmunity early
TPO and thyroglobulin antibodies rise years before the thyroid itself fails.
Explains the unexplained
Fatigue, weight changes, mood, and thinning hair often trace back here.
What we measure
Every marker, in four systems.
Thyroid hormones 4
Autoimmune markers 2
Every panel includes a live 1-on-1 review call.
About 10 to 12 days after your draw, a Rethryv physician sits down with you, on video, and reads your results together. What's strong, what to watch, and exactly what to do next. It's included free, and it's the part most people remember.

Included freeQuestions
Good to know.
Do I need to fast or test at a certain time?
Yes, an 8 to 12 hour fast gives the most accurate readings. We'll send clear prep instructions when we schedule you.
Is the physician call included?
Always. Every panel includes a free, live review call with a Rethryv physician. There's no upsell to talk to a doctor, it's the foundation of how we work.
Can I combine with other panels?
Yes, and you should. Add any other panels to your cart and we'll combine everything into one blood draw, so you're only stuck once.
Who should test their thyroid?
Anyone with unexplained fatigue, weight changes, mood shifts, or thinning hair, and anyone with a family history of thyroid or autoimmune conditions.
What will I walk away with?
A clear read on your thyroid health, the specific markers to watch, and a personal plan, including which supplements, if any, would move your numbers.
