We thank Dr. Romney1 for his response to our article.2
The guideline from the American Thyroid Association has two separate recommendations for women who test positive for thyroid peroxidase antibodies.3 The recommendations apply to those with a thyroid-stimulating hormone (TSH) level between 2.5 mIU/L and the pregnancy-specific upper limit of normal (typically 2.5–3.0 mIU/L), and those who have a TSH level greater than the reference range. There is a strong recommendation to treat those above the reference range and a weak recommendation to treat those with a level of 2.5–3.0 mIU/L. Our statement in point four combined both of these groups.
