Full Thyroid Check

A dedicated thyroid panel measuring five biomarkers including TSH, free T3, free T4, and thyroid antibodies. Goes beyond the standard TSH-only test that most GPs order, enabling detection of subclinical thyroid dysfunction and autoimmune thyroid conditions like Hashimoto's disease.

The Full Thyroid Check measures the complete thyroid hormone cascade — TSH (the pituitary signal), free T3 (the active hormone), and free T4 (the precursor) — along with thyroid antibodies that reveal autoimmune thyroid conditions. Standard GP thyroid screening typically only measures TSH, which can appear normal even when free T3 or T4 levels are suboptimal. Thyroid antibodies are particularly important because autoimmune thyroiditis (Hashimoto's disease) is the most common cause of hypothyroidism in Australia. Antibodies can be elevated years or even decades before TSH becomes abnormal, providing a crucial early warning window for intervention. This panel is especially relevant for those experiencing unexplained fatigue, weight changes, hair thinning, mood disturbances, or temperature sensitivity — all symptoms that can have thyroid origins but are often attributed to stress or ageing. Results arrive within 24-48 hours with full reference ranges.
