What this test is
This panel typically includes T3 uptake, T4, and a calculated T7 index, which together provide a picture of thyroid hormone activity. It is used to help evaluate symptoms that may be related to an overactive or underactive thyroid.
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
What the test involves
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.
Why it is often ordered
A clinician may order this test if you have symptoms such as unexplained weight changes, fatigue, or heart rate changes that could be linked to thyroid function. It can also be used to monitor thyroid status over time.
Preparation
Preparation instructions can vary, so follow the specific directions provided by the collection lab. In general, no special preparation is required, but always confirm with the lab beforehand.
How results are reported
