What is a Free T4 Test?

A free T4 test is a blood test that measures the amount of free thyroxine hormone circulating in your bloodstream. The test requires a blood sample drawn from a vein in your arm. This test helps doctors diagnose thyroid disorders, including hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid).

Frequently asked questions

Find quick answers to the most common questions about health tests, bookings, and reports.

The free T4 test can generally be taken at any time of day. However, for consistency in monitoring your condition, it's best to follow your doctor's specific instructions or take the test at the same time for subsequent check-ups.

No, fasting is not required for the free T4 test alone. You can eat and drink normally before the test. However, if other tests are ordered simultaneously, your doctor may advise fasting.

Yes, severe dehydration can concentrate your blood and potentially affect test results. It's recommended to stay adequately hydrated before any blood test for accurate results.

No special diet is needed. However, inform your doctor about all medications, vitamins, and supplements you're taking. High-dose biotin supplements should be stopped at least 8 hours before testing as they can interfere with results.
