Thyroid Profile II, Comprehensive
Also known as: Thyroid Profile D (Comprehensive)
Use
The Thyroid Profile II, Comprehensive test is used to assess thyroid function by measuring several thyroid-related hormones. These hormones include Thyroid-Stimulating Hormone (TSH), Thyroxine (T4), Tri-iodothyronine (T3), and indices that help in the diagnosis and management of thyroid disorders such as hyperthyroidism and hypothyroidism. Evaluating these markers in combination gives a comprehensive view of thyroid activity and can assist healthcare providers in diagnosing and managing patients with thyroid dysfunctions.
