Thyroid cancer blood test advice needed please.

[AnnieJo41]

Hello,

I have had a total Thyroidectomy for Thyroid cancer. My Thyroid gland was removed in two operations in 2022 and 2023, and I had RAI also. I have been having a blood test every six months the last TSH result was 0.53. I am on Levothyroxine tablets 100mg. I usually have my blood tests in the afternoon but I understand it is better to have the test done at 9am and then take the Levothyroxine after the test. If I do this am I likely to see my TSH test result higher or lower than previously?
