I am about to do a blood test. I normally take T3 at 8am and 8pm and T4 at 8am. I am hoping to do blood test at 8am, so should I take the previous eve dose of T3 at 9pm and the morning dose of T3 and T4 after the blood test, please? Just want to be sure I get this right. Thanks π

It will be fine to take your last dose of T3 anywhere between 8pm and midnight the night before, the time gap should be 8-12 hours.
Take your last dose of Levo at 8am as normal the day before the test.
After the test, take that day's Levo and first dose of T3.
