In brief: Yes.
The mother needs both a free-t3 and TSH drawn early in pregnancy, followed up monthly measurements during the pregnacy.
Most women have a significant increase in total T4 and t3, (liothyronine) due the hyperestrogenemia, which occurs with a secondary increase in thyroid binding globulin. Free thyroid levels will fall if a women is on thyroid, and may fall if reserve has been decreased by hashimoto's.
