The FT3, FT4, RT3, and TSH Panel provides a comprehensive evaluation of thyroid function and hormonal regulation. By measuring free triiodothyronine (FT3), free thyroxine (FT4), reverse triiodothyronine (RT3), and thyroid-stimulating hormone (TSH), this panel offers insight into thyroid hormone production, peripheral conversion, and regulatory feedback. It is commonly used to assess thyroid balance, investigate symptoms related to metabolic or energy changes, and support a more nuanced understanding of overall thyroid and endocrine health.
