• Fatigue: persistent tiredness or low energy levels.

• Skin and hair changes: dry skin, brittle nails, hair loss or thinning eyebrows.
• Menstrual irregularities: heavy, irregular or disrupted menstrual cycles.
• Mood symptoms: low mood, depression or emotional changes.
• Autoimmune thyroid disease: evaluation in the context of suspected or known autoimmune thyroiditis.

Overview

The Elite Thyroid Profile (T4, Tgbn, TSH, fT3, fT4, TPOab) measures total thyroxine, free thyroxine, free triiodothyronine, thyroid stimulating hormone, thyroglobulin and thyroid peroxidase antibodies using a finger-prick bloodspot sample. Together, these markers provide a broad overview of thyroid hormone production, circulating hormone availability, iodine-related markers and autoimmune activity.

Clinically, this profile may be useful when individuals present with symptoms suggestive of altered thyroid hormone activity, including fatigue, weight changes, cognitive symptoms or temperature sensitivity. Inclusion of thyroglobulin can add context related to iodine status, while TPO antibodies are commonly assessed when autoimmune thyroid involvement is considered.

Practitioners typically interpret results alongside symptom presentation, medical history, dietary factors and other relevant laboratory findings. When reviewed in context, the profile can support informed discussions with clients about thyroid-related hormone patterns and symptom variation.
