Hi Elaine,

I had labs a couple times since I last posted to you in June.

August 28:
TSH 0.021 L (0.47-4.68)
FT3 5.31 (2.45-5.93)
FT4 1.20 (0.78-2.44)
his comment was good values no change in dose.

July 27:
TSH 1.56 (0.47-4.68)
FT3 4.24 (2.45-5.93)
FT4 0.74 L (0.78-2.44)
He lowered methimazole from 20 to 10 mg.

June 8, 2023
TSH 0.132 L (0.47-4.68)
FT3 4.91 (2.45-5.93)
FT4 1.3 (0.78-2.44)
I'm still taking 20 mg. methimazole, since February 20, 2023

You made this comment after June's labs but I do not know what you mean by it:
"With your FT3 at a nice level, if you weren't on MMI it would be too high."

I still haven't had any afib since late March when my only abnormal lab was a low TSH. My numbers seem to take turns being abnormal and all three haven't been in the normal range since May 2022. I had hundreds of episodes of afib from October 2022-March 2023. I was also diagnosed with invasive ductal carcinoma in May 2023. I had a central mastectomy instead of a lumpectomy because of the position of the tumor. I started radiation yesterday and will not need chemo. (thankfully)

Since he lowered my dose at the end of July and ordered labs for one month, which I had Monday, how soon should I request labs again? I assume the lower dose takes a while to be reflected in the labs. I don't have a follow up appointment scheduled and he didn't mention in his comment when to have labs again. I really didn't have specific symptoms last fall when things went crazy plus with radiation I don't trust my symptoms anyway.

Thanks, Pam

Hi Pamela Jean,
I meant that if you weren't on MMI you'd have a high FT3 and it looks like the 10 mg dose is working. You could have labs anytime now to make sure your levels are stable. best, elaine

I see you have a new post so I'll check it next
