  • Venous blood draw
  • Laboratory analysis of Free T3, Free T4 and TSH
  • Comprehensive results report
  • Brief clinician review

Thyroid Profile 3 (FT3/FT4/TSH) (Venous) evaluates three thyroid hormones: Free T3, Free T4 and TSH. It offers a broader view of thyroid activity than the two‑marker panel. Designed for adults needing a thorough thyroid assessment, it includes a venous blood draw plus a £50 phlebotomy surcharge on the £125 lab fee.

About this treatment

Thyroid Profile 3 (FT3/FT4/TSH) (Venous) measures three key thyroid biomarkers—Free T3 (triiodothyronine), Free T4 (thyroxine) and Thyroid‑Stimulating Hormone (TSH)—to provide a comprehensive assessment of thyroid function. By evaluating both T3 and T4 alongside TSH, the panel may support more detailed discussions about metabolic rate, energy levels, and potential thyroid disorders. This test is intended for adults who require an in‑depth thyroid evaluation, such as those with ambiguous symptoms or on thyroid medication. A venous blood sample is taken, and the laboratory cost is £125 with an additional £50 phlebotomy fee per visit. Results are typically available within a few days, accompanied by a full report and a short clinician‑led review. Unique aspects include the three‑marker composition and its focus on a complete thyroid hormone profile.

Panel categories

Thyroid Panel

Biomarkers tested

3
Free T3 (Triiodothyronine) pg/mL

The active form of thyroid hormone responsible for regulating metabolism, energy, and body temperature. Free T3 is converted from T4 in tissues and is three to four times more potent than T4.

Free T4 (Thyroxine) ng/dL

The unbound, active form of the main thyroid hormone T4. Free T4 directly reflects thyroid gland output and is used alongside TSH to diagnose and monitor thyroid disorders.

TSH (Thyroid-Stimulating Hormone) mIU/L

The primary screening test for thyroid function. TSH is produced by the pituitary gland to regulate thyroid hormone production. High TSH indicates an underactive thyroid (hypothyroidism), while low TSH suggests an overactive thyroid (hyperthyroidism).
