I have an appointment with my private endo at the end of the month and was wondering whether I need to delay taking my T3 24 hrs prior to the test? I always leave my T4 before it but I have to split my T3 as it’s taken in 2 doses, one in the morning and one in the afternoon.

There is a pinned post with details of dosing for blood test timings. healthunlocked.com/thyroidu...
For T3 the maximum time is 8-12hrs, so delay 2nd dose that day before the test.
