Fasting blood test for a1c & thyroid

[Suzi_]

I am going to have my fasting blood test on Thursday am. I take 50 mcg Levo and 5 mcg of cytomel on empty stomach @ 7 am daily.

Am I right - skip both meds morning of the blood test, Thursday.

take both meds after the blood test.

Usually recommended to take bloods 24 hours after Levo and 10-12 after last dose of liothyronine. You could split your cytomel dose in half and talk last bit before bed.

Day before test split T3 into 2 x 2.5mcg and take last 2.5mcg at 9pm assuming test at 9am

Last dose levothyroxine 24 hours before test
