What this test is
This panel typically includes thyroid-stimulating hormone (TSH) along with other thyroid hormone measurements, such as T4 and T3 uptake. Together, these markers help assess whether the thyroid is underactive, overactive, or functioning within a typical range.
What it measures
- TSH — reflects how much thyroid-stimulating hormone is being produced
- T4 — reflects the level of thyroxine, a main thyroid hormone
- T3 uptake — helps estimate how much thyroid hormone is available to tissues
- T7 — a calculated value that combines T3 uptake and T4 results
What the test involves
The test requires a standard blood draw, usually from a vein in your arm. No urine sample or other collection method is needed.
Why it is often ordered
A clinician may order this panel if you have symptoms that could relate to thyroid function, such as fatigue, weight changes, or heart rate changes. It is also used to monitor thyroid function in people who are already being treated for a thyroid condition.
Preparation
Preparation instructions can vary, so follow the specific directions provided by the collection lab. In some cases, fasting or timing the test around medications may be recommended.
How results are reported
Results are reported as numerical values for each marker, and the lab may include a reference range for comparison. Reference ranges differ between laboratories, so your results should always be interpreted using the range provided by the testing lab.
