About this test

Discover why normal thyroid blood tests can miss functional issues. Our advanced Gut-Thyroid Test tracks 58 specific markers to optimise your health.

A growing body of published research has established a clear relationship between gut microbiome imbalances and thyroid dysfunction, with investigated conditions including Hashimoto's thyroiditis, Graves' disease, hypothyroidism, and disrupted TSH regulation.

The Gut-Thyroid Function Test provides a comprehensive assessment of these root cause pathways, identifying both the beneficial bacteria required for healthy thyroid function and the pathogenic species known to disrupt it.

The panel analyses 58 specific markers, covering bacteria, archaea, pathogenic organisms, fungi and parasites. This includes 12 functional thyroid pathways, utilising the most advanced stool testing technology currently available in clinical practice.
