The Essential Thyroid Profile measures thyroid stimulating hormone (TSH), free T3, free T4 and thyroid peroxidase (TPO) antibodies using a bloodspot sample. These markers offer practitioners a focused overview of thyroid related hormone patterns, including circulating hormone levels and the presence of thyroid specific antibodies.
Clinically, this assessment may be useful when exploring concerns such as changes in energy, cognitive function, weight patterns, temperature sensitivity, menstrual rhythm variations, or skin, hair and nail changes. Reviewing TSH alongside free T3 and free T4 provides insight into how thyroid hormone production and availability may relate to a client’s presentation, while TPO antibodies add context where immune activity involving the thyroid is under consideration
