TSH is a hormone made by the pituitary gland that signals the thyroid to produce thyroid hormones. It is part of the feedback system that helps regulate metabolism and energy.
Pituitary signal that helps regulate thyroid hormone production.
Supports thyroid wellness education when interpreted alongside Free T4, Free T3, and symptoms with a clinician.
Part of: Thyroid Panel
Free T4 is the unbound (active-available) form of thyroxine, one of the main thyroid hormones. The body can convert T4 into T3, the more active thyroid hormone.
Unbound thyroxine available in blood.
Provides context for thyroid hormone availability; best interpreted with TSH and Free T3.
Part of: Thyroid Panel
Free T3 is the unbound (active-available) form of triiodothyronine, the thyroid hormone that most directly influences metabolic rate, temperature regulation, and energy.
Unbound active thyroid hormone available in blood.
Used in thyroid wellness education for metabolic signaling context; interpret with a clinician.
Part of: Thyroid Panel
TPO antibodies are immune proteins that can target thyroid peroxidase, an enzyme involved in thyroid hormone production. Their presence may suggest thyroid-directed immune activity.
Antibodies that may indicate thyroid-directed immune activity.
Helps contextualize thyroid wellness and whether follow-up with a licensed provider is warranted.
Part of: Thyroid Panel
Thyroglobulin antibodies are immune proteins that can target thyroglobulin, a thyroid-related protein. Their presence may suggest thyroid-directed immune activity.
A laboratory biomarker measured from your sample.
This marker can provide educational insight into general wellness domains such as metabolism, nutrient status, organ function, inflammation, or hormonal signaling. Interpretation depends on context, symptoms, medications, and timing.
