In 1991 PRESIDENT BUSH was diagnosed with and treated for thyroid imbalance and Mrs. Bush and her Springer Spaniel had complete thyroid panels run. (thedogplace.org)
I recommend a complete thyroid panel that includes TSH, total T4, free T4, total T3, free T3, reverse T3, anti-TPO antibodies, and anti-thyroglobulin antibodies. (mindbodygreen.com)
