The Comprehensive Thyroid Panel is a systems-based evaluation of thyroid function that goes far beyond basic screening. It includes all major thyroid hormones and functional thyroid markers, along with key nutrients, vitamins, minerals, and metabolic cofactors that influence thyroid production, conversion, and cellular response. This allows patterns such as impaired T4 to T3 conversion, nutrient-driven thyroid dysfunction, inflammatory interference, and metabolic slowdown to be identified clearly rather than overlooked. The goal is a complete, functional view of thyroid health, from hormone signaling to the support systems that regulate it.
