Last dose of T3 before blood test ?

[LynLyn]

Please advise when I should take my last dose of T3 before having blood tests. I currently take 12.5mcg at 9am, 4pm and 10pm. I have my blood tests between 8 and 9am fasting. Thank you.

8 to 12 hours before the test.

We always say last dose of T3 should be 8-12 hours before blood draw, splitting dose and adjusting time the day before if necessary.

If you do a test between 8-9am then your current dose regime is perfect and doesn't need changing.
