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.

Panel Categories
Biomarkers Tested
8The 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.
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.
Free triiodothyronine; high levels indicate hyperthyroidism, low levels hypothyroidism.
Free thyroxine; high levels indicate hyperthyroidism, low levels hypothyroidism.
A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.
An inactive form of T3 produced when the body converts T4. Elevated reverse T3 can occur during illness, stress, or caloric restriction and may indicate impaired thyroid hormone activation despite normal TSH levels.
Antibodies against thyroid peroxidase, an enzyme essential for thyroid hormone production. Positive TPO antibodies indicate autoimmune thyroid disease, most commonly Hashimoto's thyroiditis, even before symptoms or TSH changes appear.
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).
