tomorrow I go for testing at 1:30 pm and the question is should I take my regular dose of 50 mcg synthyroid and 5mcg of cytomel at about 6:30 in the morning. Should I take the cytomel the morning of my test? Or should I just take the synthroid? Please help

The T3 in Cytomel is so quick acting that I always wait until after the blood draw for the test. That way you don't get a false picture of the level of T3 in your blood.

The max effect for a T3 med is at about 3 hours, and then it dissipates over the rest of the day. So you should be okay.

Thanks so much for the reply but my internet went down so I did'nt know what to do. I did take the cytomel at 7;00 am and did not get the blood work done until 2;00 pm. so that's about 7 hrs. Not sure if that's enough time to work it out of my system. I guess time will tell. thank you
