The test measures key thyroid function parameters including Free Triiodothyronine (FT3) and Free Thyroxine (FT4), which are active thyroid hormones involved in metabolism regulation. It also evaluates Thyroid Stimulating Hormone (TSH ULTRASENSITIVE) to assess thyroid activity. Additionally, the test checks for the presence of Anti-Thyroid Peroxidase Antibodies (Anti-TPO) and Anti-Thyroglobulin Antibodies (Anti-TG), which can indicate autoimmune thyroid conditions such as Hashimoto's thyroiditis or Graves' disease. These results help diagnose and monitor thyroid health and autoimmune disorders.
