Thank you Leslie! I learned so much from your class!
I have a question about TSH levels. My patient's TSH level was 4.51 when tested at the beginning of her pregnancy. She miscarried at the end of her first trimester. The day after her miscarriage her TSH level was tested and it was 2.75. Then about a month later it was 3.30. (All other thyroid and hormone tests you recommended were run and everything was within the normal range that you recommend). This was her 3rd miscarriage. She is 40 years old and is in otherwise great health. Is it normal for the TSH to fluctuate this much? I understand that the functional range should be between 1-2. But the labs say that between 1-4.5 are normal. Do you think this is a factor affecting her ability to carry a pregnancy to term?
I really appreciate your help!!
