Blood tests & medications

Hello, just wondering if anyone could advise me on when to take my medication before I have a blood test. :)

At the moment I take 12.5mg of T3 at 8am in the morning, then the other half (12.5mg) at 2pm, as told to me by my Private Endo, and then 75mg of Levo at night, at bedtime.

He told me to take my Levo the night before and then my T3 at 8am as normal, but wait 2 hours (10am) until having my blood taken.

Is this correct? I got wrong last time, so want to make doubly sure!

Thank you very much for any help :)

Bellerin It's generally suggested here to leave off Levo for 24 hours and T3 for 12 hours before testing, fast overnight and have blood draw as early as possible in the morning, no later than 9am.

I adjust timing of my meds accordingly the day before I do my test.
