Your TSH Came Back Normal. So Why Do You Still Feel Like This?
Fatigue, brain fog, weight that won't budge, hair that's thinning — if your last test said "normal" and none of that changed, here's why. A normal TSH only checks one thyroid marker. It won't catch a T4-to-T3 conversion problem, shown by Reverse T3, or early autoimmune thyroid disease, shown by TPO and thyroglobulin antibodies — both of which can cause real symptoms years before TSH itself changes. This panel checks all six markers together, so nothing gets missed because one test looked "normal."
​
Reverse T3 shows if your hormone is actually converting, or getting blocked.
Thyroid antibodies catch autoimmune activity — often years before TSH itself moves.
What's Included in this Panel?
-
TSH: the standard first check, and only the first piece
-
Free T3: the active hormone your cells use; can run low even with a normal TSH
-
Free T4: your thyroid's raw output, before conversion
-
Reverse T3: flags a conversion problem basic panels never test
-
TPO Antibodies : present in 9 out of 10 Hashimoto's cases
-
Thyroglobulin Antibodies checked: alongside TPO, since a person can test positive for one and not the other

Why Not Just Get the Basic Test?
Most thyroid tests around Mesa and the East Valley are the basic version — TSH only.
A basic TSH test is a good first screen — it's just not built to catch everything. It misses conversion problems, and it misses autoimmune activity until it's advanced enough to push TSH out of range. That's the gap between a routine thyroid test and a real thyroid antibody test: one confirms a hormone level, the other checks whether your immune system is involved at all. If you've already had a normal TSH and still aren't convinced that's the whole story, this is the test built for exactly that — closer to what people search for as a Hashimoto's test or a full thyroid workup than a basic screen.

Full Thyroid Panel FAQ
My TSH already came back normal. Why would I need this? TSH is a good first check, but it's one piece. This adds Reverse T3 (catches conversion problems TSH can't see) and both thyroid antibodies (can be positive years before TSH moves at all).
What does Reverse T3 actually tell me? It shows whether your body is turning thyroid hormone into the active form your cells use, or making an inactive version instead — a pattern that never shows up on a TSH-only test.
What do thyroid antibodies mean? Positive antibodies mean your immune system is targeting your thyroid — the hallmark of Hashimoto's. It's often the earliest sign, showing up well before TSH itself changes.
Do I need to stop my thyroid medication first? No — just draw before that day's dose. Taking it first can shift your numbers temporarily.
