TSH paired with both free and total T3/T4, reverse T3 (the stress brake on thyroid), autoimmune antibodies (TPO + Thyroglobulin), plus selenium and iodine , the two trace minerals thyroid hormone synthesis depends on. For the visitor whose 'normal TSH' didn’t match how they actually feel.
What’s tested
biomarkers
Grouped by clinical axis. Notes flag the markers where the assay choice or interpretation matters most.
Why these matter
Thyroid Panel with TSH
Legacy bundle: TSH + Total T3 + Total T4 + T-Uptake + Free T4 Index. Provides binding-protein context the direct assays alone don’t show.
Free T4 (FT4)
Direct measurement , the modern standard, more reliable than the calculated Free T4 Index in the bundle above.
Free T3
The active hormone. Often where the actual issue lives when TSH looks normal.
Reverse T3, LC/MS/MS
The 'stress brake' on thyroid. The Free T3 : Reverse T3 ratio is often the most clinically useful number in this panel.
Why these matter
Thyroid Peroxidase and Thyroglobulin Antibodies
Catches Hashimoto’s , the most common cause of hypothyroidism, often missed when only TSH is checked.
Why these matter
Selenium
Required cofactor for the deiodinase enzymes that convert T4 to active T3.
Iodine, Serum/Plasma
Required substrate for T4 synthesis.

The other way
The panel
A snapshot. Yours to keep. Includes the lab work and a physician’s interpretation. The right move when one read is the question.
The relationship
The panel is the snapshot; ongoing care is the relationship. A membership keeps a doctor who knows you in your phone and puts your metabolism on a testing rhythm, measured and corrected at what I pay. The right move when one read isn’t the question.
