Precision Point Diagnostics' Comprehensive Thyroid Panel w/ Antibodies & Reverse T3 goes above and beyond routine thyroid tests, which only measure thyroid stimulating hormone (TSH) and total T4. It gives a comprehensive view of thyroid function by measuring TSH, T3 (free and total), T4 (free and total), reverse T3, and anti-thyroglobulin and thyroid peroxidase antibodies.
