A 63-year-old female asked:
Disclaimer

so the internist said it wasn't necessary for my mom to increase her synthroid (thyroxine) dosage of 25 mcg because she has active thyroid hormone (t3) of 2.9. do you agree?

???: Usually we use TSH to titrate the synthroid (thyroxine) dose. There may be some confusion. Better double check with her internist. Good luck, your mother will be proud of you.
