What is a normal thyroid (TSH) level ?

Question

Hi guys,

I was tested back in Dec for thyroid and Dr told me it was normal. She might have told me what it was but i can't remember for the life of me what it was.

I got tested recently for some blood work as I have RA and my Dr wanted to make sure that everything is good. She told me my thyroid is 3.3

Is that high? Do I need to bring it up to my Obgyn?  I had a mc last month at 5 weeks and I don't want to deal with that again if it's because of this.

Recommendations for Testing for Thyroid Disease During Pregnancy
The new recommendations for TSH levels during pregnancy are the following:
First trimester: less than 2.5 with a range of 0.1-2.5
Second trimester: 0.2-3.0
Third trimester: 0.3-3.0.

Answer

Understanding TSH Levels to Diagnose HypothyroidismToday experts consider 0.3 to 3.0 mIU/L the normal range for TSH levels to fall (14). Anything above 3.0 is considered hypothyroid. Some endocrinologists believe that a percentage of women may find it difficult to get pregnant — or maintain a pregnancy — at a TSH level above 2.0 mIU/L, which may indicated poor thyroid function. Some studies indicate that TSH levels should be below 2.5 mIU/L prior to conception, while other studies suggest it should be at or below 1.2 mIU/L (4).

Answer

DO bring it up. It's VERY important in the baby's development, especially in the first trimester.
