Your regular doctor can order the blood test for TSH, it's not exotic. The problem you may have is how to know what your pre TX level was, so you would have to ask your doctors plus review your copies of your blood work tests. Still can't hurt to have the blood test done. Turns out however there is controversy over what is the right TSH level with labs having a 5.5, a 4.5 even though endocrinologists who went to Medical school the 21st Century conbsider 3.0 as the highest acceptable level. Before TX, I had a TSH of 1.6 and after TX it shot up to 4.3. Now that I am "on the pill", I am finally warm again. Plus my energy is back My TSH level went down to 3 on 25 mcg ,2.1 on 50 mcg and then 1.7 on 75 mcg. It's now at 1.48 since I switched to taking it a night. Of course there could also be nothing wrong at all with your thryoid . But it worked for me. Good luck
