Thyroid & Energy Panel

A 27-biomarker panel combining a complete thyroid assessment with the nutritional and inflammatory markers that most commonly cause or compound thyroid-related fatigue. Covers full thyroid hormones (TSH, free T3, free T4), iron studies, vitamin D, B12, folate, CRP, and a full blood count — addressing the reality that thyroid symptoms often result from multiple overlapping deficiencies rather than thyroid dysfunction alone.

Fatigue, brain fog, and weight gain are the most common reasons Australians seek thyroid testing — but these symptoms are rarely caused by thyroid dysfunction in isolation. The Thyroid & Energy Panel investigates the thyroid alongside every system that mimics or compounds thyroid symptoms. The full thyroid panel (TSH, free T3, free T4) goes beyond standard GP screening to assess the actual hormones driving metabolism. Poor T4-to-T3 conversion — caused by stress, inflammation, calorie restriction, and selenium/zinc deficiency — produces hypothyroid symptoms with normal TSH. This panel would catch that pattern; a standard TSH-only screen would not. Iron deficiency causes fatigue through reduced oxygen transport and impaired mitochondrial energy production. Vitamin D deficiency affects muscle function and mood. B12 deficiency causes neurological symptoms and fatigue. Folate deficiency impairs DNA synthesis and cell division. Each of these independently causes the same symptoms as hypothyroidism — and they commonly coexist. CRP measures inflammation, which both suppresses thyroid function and drives fatigue through immune activation. A full blood count screens for anaemia and infection. This panel systematically investigates the top 6 biological causes of energy-related complaints in a single blood draw.
