It is also one of the most commonly missed diagnoses because antibody testing is often not included in standard thyroid workups. Elevated thyroid antibodies can be present for five to ten years before TSH shifts enough to trigger medication. During that time, symptoms (fatigue, hair thinning, weight gain, brain fog, cold intolerance) are often dismissed as being in normal range. This test catches the autoimmune pattern early. A positive antibody result does not automatically mean medication is needed, but it gives you and your practitioner a foundation for discussing lifestyle interventions (gluten removal, selenium, vitamin D optimisation, stress management) that have evidence behind them for slowing or reversing thyroid antibody progression.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"product-ingredients\"\u003e\n\u003ch3\u003eWhat it measures\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eBiomarker\u003c\/th\u003e\n\u003cth\u003eSample\u003c\/th\u003e\n\u003cth\u003eReference Range\u003c\/th\u003e\n\u003cth\u003eWhat it tells you\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eTPO Antibodies (Thyroid Peroxidase)\u003c\/td\u003e\n\u003ctd\u003eBlood (SST)\u003c\/td\u003e\n\u003ctd\u003eUnder 35 kIU\/L\u003c\/td\u003e\n\u003ctd\u003ePresent in the majority of Hashimoto's cases and some Graves' cases.

Over time this typically (not always) progresses to clinical hypothyroidism.

Antibody titres are not fixed. Evidence shows that selenium supplementation, vitamin D optimisation, removing gluten in sensitive individuals and treating underlying infections can reduce antibody levels in many people.
