What it measures
- T3 uptake — reflects the availability of binding sites for thyroid hormones in the blood
- T4 — measures the total amount of thyroxine, a primary thyroid hormone
- T7 index — a calculated value that estimates free thyroxine levels based on T3 uptake and T4

A blood sample is collected from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.
