About This Test

Who Is This For?

This test is often ordered as a follow-up to an abnormal TSH result, or for anyone already managing a thyroid condition who wants to monitor their hormone levels. It's also useful if you're experiencing symptoms of thyroid dysfunction — fatigue, weight changes, temperature sensitivity — and want a more specific measurement than TSH alone.

What Does This Test Measure?

Free T4 (Free Thyroxine) is the active, unbound form of the main hormone your thyroid produces. While TSH tells you how hard your pituitary gland is working to stimulate the thyroid, Free T4 tells you how much hormone the thyroid is actually releasing into your bloodstream. Together, TSH and Free T4 give a complete picture of thyroid function.
