A member asked:

Why tsh is higher at morning? is it because thyroid gland is less responsive when you wake up? does that mean t4 and t3 (liothyronine) gets also higher at morning?

A doctor has provided 1 answer

TSH: Sorry, but I don't fully understand your question. TSH, T4, and T3 (liothyronine) should always be measured on the same blood draw. TSH is higher if the thyroid is not working properly and a high T4 and/or T3 (liothyronine) would decrease TSH levels.
