TPO antibodies are made when the immune system mistakenly targets the thyroid. They’re the key marker for autoimmune thyroid disease.
High TPO antibodies are a sign of Hashimoto’s disease, the most common cause of an underactive thyroid, and they can show up before thyroid hormone levels change. Knowing this early helps your physician watch your thyroid more closely.
At Serene Med Spa in Hudson, Ohio, every hormone and wellness plan starts with Labcorp lab work reviewed by a board-certified physician.
