TSH level at 4 during first trimester
An_247120 posted:
Hi. My TSH is at 4 at a blood test conducted at 11 weeks. While my doc is saying that under 5 is not a problem, i am a little confused as all articles and the report range is also hinting at a normal range not exceeding 2.9 [at the upper end>. Is TSH at 4 ok in the first trimester. The lab has not conducted a T3, T4 and Free T3, free T4 test and i am planing to go for a new test again this week.
Robert O Atlas, MD responded:
It is a very interesting situation you find yourself in. If you had a diagnosis of hypothyroidism, I would want to increase your medication since we would like to get the TSH to approximately 1-2.

However, a TSH of 4 would not be high enough in a nonpregnant patient to warrent treatment. I agree with having it repeated and seeing what your Free T4 level is. If it is low in the least, I would agree treatment may be in order. If it is normal, I probably would not do anything.

Good luck with you. I would discuss this further with your healthcare team and then decide what it is you would like to do.
