ABOUT FREE T4 TESTS
The Free T4 test measures the unbound (free) form of thyroxine, the primary hormone produced by the thyroid gland. Free T4 is the portion available to enter tissues and regulate metabolism. This test is commonly used alongside TSH and other thyroid tests to diagnose hypothyroidism, hyperthyroidism, and to monitor treatment effectiveness.
This test is for you if you’re experiencing symptoms like fatigue, weight changes, depression, or anxiety, or if you’re being treated for a thyroid condition.
The test measures the free (active) form of T4 hormone circulating in your blood.
It helps identify whether your thyroid is producing too much or too little hormone and assists in diagnosing conditions like hypothyroidism or hyperthyroidism.
No special preparation is needed. You may take this blood test at any time unless advised otherwise by your provider.
