## What does the Complete Thyroid Panel cover?

The most thorough thyroid assessment — TSH, Free T4, Free T3, Reverse T3, and TPO Antibodies.

The Complete Thyroid Panel combines every major thyroid marker into a single comprehensive order. It includes TSH, Free T4, Free T3, Reverse T3, and TPO Antibodies. This is the panel functional medicine practitioners often recommend because it evaluates not just whether the thyroid is working, but how well it's converting T4 to active T3, whether reverse T3 is blocking thyroid function, and whether autoimmune thyroid disease is present.

**Clinical use:** 5 thyroid tests: TSH, Free T4, Free T3, Reverse T3, TPO Antibodies. The most thorough single-draw thyroid evaluation — distinguishes primary vs central, conversion issues, and autoimmune causes.

## Who should order it?

Anyone with classic thyroid symptoms (fatigue, weight changes, cold intolerance, hair thinning, brain fog) whose TSH alone hasn't given clear answers, anyone managing known thyroid disease, anyone with autoimmune disease (T1 diabetes, celiac, RA) checking for thyroid involvement.

## Common questions about the Complete Thyroid Panel

### What's included in the Complete Thyroid Panel?

Five tests: [TSH](https://www.test-well.com/tests/tsh) (screening), [Free T4](https://www.test-well.com/tests/free-t4-test) (active circulating thyroxine), [Free T3](https://www.test-well.com/tests/free-t3) (the most metabolically potent form), [Reverse T3](https://www.test-well.com/tests/reverse-t3) (inactive 'brake' form), and [TPO Antibodies](https://www.test-well.com/tests/tpo-antibodies) (autoimmune marker). Together they distinguish primary vs central hypothyroidism, T3 toxicosis, autoimmune cause, and impaired peripheral conversion.

### How is this different from just TSH?

[TSH](https://www.test-well.com/tests/tsh) alone catches most primary thyroid disease, but misses central (pituitary) cause, T3 toxicosis, conversion problems, and silent autoimmune thyroiditis. Thyroid Complete catches all of those. If you have classic thyroid symptoms with a 'normal' TSH, this panel is the right next step.

### What does Reverse T3 add?

[Reverse T3](https://www.test-well.com/tests/reverse-t3) is the inactive form your body produces under stress, illness, or caloric restriction. Elevated rT3 with normal [TSH](https://www.test-well.com/tests/tsh) and [Free T4](https://www.test-well.com/tests/free-t4-test) can indicate stress-induced 'cellular hypothyroidism' or impaired T4-to-T3 conversion — explaining symptoms that the standard tests miss. Mainstream endocrinology is skeptical; functional medicine relies on it heavily.

### What do TPO Antibodies indicate?

Positive [TPO Antibodies](https://www.test-well.com/tests/tpo-antibodies) suggest autoimmune thyroid disease (Hashimoto's), the most common cause of hypothyroidism in the US. They can be elevated for years before TSH abnormalities appear — useful for risk-stratifying and timing repeat TSH monitoring.

### How much does the Complete Thyroid Panel cost without insurance?

On TestWell, the Complete Thyroid Panel is $109.99. Ordering the same 5 tests separately would be about $135. Quest Direct lists comparable bundles at $195, walk-in hospital labs typically bill $400-600 for the same biomarkers without insurance.

### Do I need to fast?

No fasting required for thyroid tests. Draw at the same time of day for serial monitoring (TSH has a mild circadian rhythm), and at least 4 hours after your levothyroxine dose if on thyroid replacement therapy.

### Should I add Thyroglobulin antibodies?

Optional — about 5% of Hashimoto's patients are TPO-negative but Thyroglobulin-positive. The standalone [Thyroid Antibodies](https://www.test-well.com/tests/thyroid-antibodies) bundle includes both. If you've already tested TPO-positive, adding Thyroglobulin Ab rarely changes management.

### How often should I retest?

Annually if you have known thyroid disease that's well-managed. Every 6-8 weeks when starting or adjusting levothyroxine. Every 3 months in pregnancy or postpartum. Once for baseline if you're TPO-positive but euthyroid.
