Does your wife have symptoms of hyperthyroidism? Is she on any type of thyroid medication?
What are the actual results of the T4 and T3, and are they for Free T3 and Free T4 or are they total T3 and total T4? There's a difference. Also, please be sure to post the reference ranges with the results, as these vary lab to lab, so must come from her own report.
Congratulations. Just wanted to stop by and welcome you to the the community. We are patients on the community so we may not have an answer for you. Feel free to post your question here to ask a doctor, perhaps.
