Just asking for some clarity about the statement I hear often on this forum, to wait 8 to 12 hours before a blood test after taking the last dose of T3.
Question: Should one actually time the last dose of T3 to be 8 to 12 hours before the test? Or if taking T3 in the morning of the day before blood test; will 24 hours after that dose be too long without T3 in the blood, and result in too low FT3 on the test?
I'm hoping I have asked this question clearly, and hope it doesn't seem a stupid question. Thanks in advance.
