Hello again... I just want to ask how long should I go off/withdrawal from my levothyroxine medication (125 mg thyrax) before my tg level blood test as a routine check of any recurring papillary CA? I am from the Phillippines and thyrogen injections here is very costly and i cant afford it. My endo said I have to be off thyroid drugs for 2 weeks before the tg blood test. Is that enough to make me hypothyroid?
How long should i go off levothyroxine. I am scheduled for my tg level 3 mos from now. Any inputs is very much appreciated
