Hashimoto's thyroiditis is the most common cause of an underactive thyroid in the United States, and diagnosing it takes two kinds of information: how the gland is functioning (TSH and free T4, with free T3 for the active hormone) and whether the immune system is attacking it (thyroid peroxidase and thyroglobulin antibodies, positive in roughly 90% of cases). Ordering them separately means two visits and often a missed antibody; this panel runs all of them from one blood draw. It is the right test when TSH has come back borderline, when hypothyroid symptoms — fatigue, weight gain, cold intolerance, hair thinning, constipation, brain fog — persist with a 'normal' TSH, when a family member has autoimmune thyroid disease, or when you are planning pregnancy, since untreated thyroid autoimmunity matters for fertility and early pregnancy. No fasting is needed; if you take thyroid medication, draw before your morning dose.
Thyroid testing measures the hormones that regulate metabolism, energy, body temperature, weight, and mood — identifying both overactive and underactive thyroid conditions.
Anyone with fatigue, weight changes, mood changes, hair loss, cold/heat intolerance, irregular cycles, or family history of thyroid disease.

Biotin supplements, levothyroxine timing and ashwagandha and thyroid-support supplements can change a Hashimoto's Thyroid Panel result without anything being wrong. Biotin supplements can falsely lower TSH and can falsely raise Free T4 — stop biotin ≥72 hours before the draw. Levothyroxine timing can raise Free T4 and Free T3 — draw before the daily dose, then take it. Ashwagandha and thyroid-support supplements can lower TSH and can raise Free T4 — note the supplement on a thyroid panel; a clinician may repeat TSH after a planned pause. Each is explained on our physician-reviewed "Before your test" pages; when one applies, remove it and retest.
