Thyroid Function

TSH (Thyroid-Stimulating Hormone)
TSH controls how much thyroid hormone your body makes. It’s often the first marker checked when evaluating thyroid health.

Free T3 (Triiodothyronine)
This is the active thyroid hormone that helps regulate metabolism, energy, and body temperature.

Total T4 (Thyroxine)
Measures the total amount of T4 hormone (both bound and unbound) in your blood to assess overall thyroid output.

T3 Uptake
T3 Uptake helps estimate the number of binding proteins available for thyroid hormones and assists in calculating the Free Thyroxine Index.

Free Thyroxine Index (FTI)
A calculated value that provides insight into active thyroid hormone levels, especially when protein levels fluctuate.

Thyroid Autoimmunity

TPO Antibodies (Thyroid Peroxidase Antibodies)

Elevated TPO antibodies suggest autoimmune thyroid disease, such as Hashimoto’s or Graves’ disease, even if other thyroid markers are normal.
