Liothyronine

Hi I always skip levothyroxine before a blood test should I do the same with liothyronine?

Last dose of T3 should be 8-12 hours before blood draw, even if it means altering time and splitting dose the day before.

Last dose of Levo should be 24 hours before blood draw.

Any longer than these times then you get false low results, take them too close to the blood draw and get false high results.

Important to test vitamin D, folate, ferritin and B12 too
