Timings of levo and t3 before test

[Mickeydooley]

I’m hoping to do a blood test on Tuesday morning about 8.30am, fasted and having taken levo and t3 24 and 12 hours prior as recommended here. However I generally take 3 doses of t3 during the day - 5mcg at 11pm, 10mcg about 6am and 5mcg at 3pm. I know to take the last dose (5mcg) at 8.30pm on Monday night but my question is do I still take the 10mcg at 6am and the 5mcg at 3pm or will that be too much t3 prior to the test?

You take all your T3 as normal the day before the test, just adjusting the time of the last dose if necessary.

The time gap for last dose of T3 is 8-12 hours before the test, so taking your 11pm dose as normal will be fine, no need to alter it.

Thank you. I was a bit confused because when I did a test last time and my t3 levels ended up above range I’d taken last dose about 11 hours prior to test and was advised in future to leave 12 hours. X
