What this test reveals
What this test reveals
A comprehensive thyroid panel measures TSH, free T4, free T3, reverse T3, thyroid antibodies (TPO and TG), and thyroglobulin — providing a complete picture of thyroid production, conversion, autoimmunity, and cellular resistance.
The standard TSH-only test misses the vast majority of thyroid dysfunction. You can have normal TSH but terrible T4-to-T3 conversion, sky-high reverse T3 blocking thyroid receptors, or raging thyroid antibodies attacking your gland for years before TSH rises. Millions of people suffer with hypothyroid symptoms while being told they're 'fine' based on TSH alone.
People usually reach for this kind of diagnostic when they want a clearer read on tsh (pituitary thyroid signal), free t4 (inactive thyroid hormone), free t3 (active thyroid hormone), especially when symptoms or prior testing still leave blind spots.
Once results are back, you can upload them into Gabriel to connect the findings to symptoms, protocols, and next-step testing instead of leaving them as a static report.
Commonly relevant for: Hashimotos Thyroiditis, Chronic Fatigue Fibromyalgia, Weight Management Metabolic Health.
Gabriel difference
Why this becomes more useful inside Gabriel
TSH is a terrible screening test. Functional thyroid dysfunction shows up in free T3, reverse T3, and antibodies long before TSH budges. Gabriel sees hundreds of patients with 'normal TSH' who are freezing, exhausted, losing hair, and gaining weight — because their T4 isn't converting to T3, or reverse T3 is sky-high, or antibodies are silently destroying their thyroid. A comprehensive panel reveals the truth and guides targeted thyroid support: selenium and zinc for conversion, LDN for antibodies, T3 medication when needed.
Gabriel interprets results through a functional, root-cause lens: optimal ranges, pattern recognition across multiple diagnostics, and what the findings actually mean for action rather than just classification.
That means this test can feed directly into protocols, practitioner matching, food strategy, and follow-up testing instead of ending as a one-off PDF or lab portal result.
What to expect
What to expect from ordering to results
01
Order
Order directly through Ulta Lab Tests or ask Gabriel whether there is a better path first.
02
Complete
A standard blood draw at a local lab, ideally done in the morning before 10 AM (TSH is highest in the morning). No fasting required, but avoid biotin supplements for 72 hours before the test (biotin interferes with thyroid assays).
03
Interpret
Upload the results to Gabriel for pattern recognition, protocol suggestions, and next-step guidance.
Frequently asked questions
Questions people usually ask before ordering
TSH alone misses a lot. A comprehensive panel includes free T3, free T4, reverse T3, thyroid antibodies (TPO and TG), and TSH. You can have a normal TSH with low free T3 (poor conversion), elevated reverse T3 (stress response), or positive antibodies (Hashimoto's) that a TSH-only test would never catch.
Lab 'normal' ranges are based on population averages, including sick people. Functional ranges are tighter. For example, conventional TSH normal is 0.5-4.5, while functional optimal is 1.0-2.0. Free T3 optimal is 3.0-4.0 pg/mL vs the broad 2.3-4.2 range. Many people feel best in the functional range.
Elevated TPO or thyroglobulin antibodies indicate autoimmune thyroid disease (usually Hashimoto's). This means your immune system is attacking your thyroid. Antibodies can be elevated for years before TSH becomes abnormal, making early detection possible with comprehensive testing.
Usually yes, if your doctor orders it with appropriate diagnosis codes (fatigue, weight changes, thyroid symptoms). Some doctors resist ordering the full panel, preferring TSH only. If you encounter resistance, a functional medicine practitioner will typically order the complete panel without hesitation.
A comprehensive thyroid panel (TSH, free T3, free T4, reverse T3, TPO, TG antibodies) typically costs $100-200 through direct-to-consumer labs like Ulta Lab Tests or Walk-In Lab. Through a practitioner, it may be higher but includes interpretation.
