In medicine, subclinical hypothyroidism is an elevated thyrotropin (TSH) concentration can maintain a normal or near normal thyroxine (T4) concentration.[1][2][3]
Prognosis
Thyrotropin level=
The thyrotropin level helps predict progression to overt hypothyroidism.[4]
Antithyroid peroxidase antibodies
Antithyroid peroxidase (also called antithyroid microsomal) antibodies my help predict progression to overt hypothyroidism.[5]
Screening
The US Preventive Services Task Force states:[1]
- "t is uncertain whether treatment will improve quality of life in otherwise healthy patients who have abnormal TSH levels and normal free thyroxine levels"
