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.
Anyone with a borderline or abnormal TSH, persistent hypothyroid symptoms despite a normal TSH, a family history of autoimmune thyroid disease, other autoimmune conditions (celiac, type 1 diabetes, vitiligo), or who is planning pregnancy.

No fasting required. If you take levothyroxine or other thyroid medication, have blood drawn before your morning dose. Pause high-dose biotin for 48 hours — it interferes with thyroid immunoassays.
