Depends on lab range: Likely subclinical hypothyroidism: when TSH is above normal and FT4/FT3 or T3/T4 are normal. This condition is typically caused by immune damage (hashimotos thyroiditis) to the thyroid, evidenced by your elevated thyroid peroxidase ab test. This results in a 2-4% per year risk of becoming overtly hypothyroid and 33-55% lifetime risk. https://www.thyroid.org/hashimotos-thyroiditis Be well, Dr. W
