And FYI the “normal” range for TSH from the medical system is between 0.4 - 4.8
Through a naturopath 1.5 - 2.0
There’s a big difference between functional and optimal..

A full thyroid panel gives you a more complete picture of thyroid function than just TSH alone. This is especially important for people with Hashimoto’s, hypothyroidism, or those who’ve had a thyroidectomy.
-TSH (Thyroid-Stimulating Hormone)
What it is: A hormone made by your pituitary gland to tell your thyroid to make hormones.
Why it matters: It's the primary screening test, but not always reflective of how well your body is using thyroid hormones.
- FREE T4
What it is: The unbound, active form of thyroxine (T4) — the main hormone your thyroid (or thyroid meds) produce.
Why it matters: T4 is the storage form, which gets converted into T3, the active hormone
-FREE T3
What it is: The active form of thyroid hormone — this is what your cells actually use.
Why it matters: Many symptoms (fatigue, brain fog, weight gain) are tied to low T3, even if TSH and T4 are “optimal”
-REVERSE T3
What it is: An inactive version of T3 — it blocks the action of real T3 at the cellular level.
Why it matters: High rT3 can cause hypothyroid symptoms even if TSH and T4 look OK. Often elevated with:
Stress
Illness
Inflammation
Too much T4
-TPO Antibodies (TPOAb)
What it is: Antibodies that attack thyroid peroxidase, an enzyme used to make thyroid hormones.
Why it matters: A hallmark of Hashimoto’s thyroiditis. High levels = active autoimmune attack.
-Thyroglobulin Antibodies (TgAb)
What it is: Antibodies against thyroglobulin, a protein in thyroid cells.
Why it matters: Also seen in Hashimoto’s or thyroid cancer follow-up. May interfere with thyroglobulin testing in cancer patients.
🚩Thyroglobulin (Tg) — For Patients Post-Thyroidectomy
What it is: A protein made by thyroid cells.
Why it matters: After a total thyroidectomy (especially for cancer), it’s used to detect recurrence or remaining tissue.
