Free Thyroxine Index (FTI) Test
$49.00
Experiencing unexplained weight changes, fatigue, hair loss, or sensitivity to temperature? The Free Thyroxine Index (FTI) Test can provide important insights into your thyroid health.
This thyroid function test calculates the ratio of free thyroxine (T4) to thyroxine-binding proteins, offering a clearer picture of how well your thyroid is working. Abnormal FTI levels may suggest hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid).
Healthcare providers use the FTI test alongside other thyroid evaluations to diagnose thyroid disorders, monitor treatment, and guide medication adjustments.
By understanding your FTI results, you can work with your provider to effectively manage thyroid health, address symptoms early, and improve your overall well-being.
