Your doctor may order a Free T4 test in several conditions for him or her to assess the levels of Free T4 and how well your thyroid is working:
- Thyroid Function Evaluation: If a patient exhibits symptoms of thyroid dysfunction, such as fatigue, weight changes, or changes in mood, a T4 Free test may be ordered as part of a comprehensive thyroid function evaluation.
- Monitoring Thyroid Hormone Therapy: For individuals undergoing thyroid hormone replacement therapy, a T4 Free test helps assess the effectiveness of the treatment and ensures that the free T4 levels are within the target range.
