tsh and free t4 levels during first trimester of pregnancy
hi there, I'm in first trimester of pregnancy with a tsh level of 2.38 and a free t4 range of 7.2, are both levels normal?

Did you not get an actual copy of the lab report? I've never seen a lab report that didn't have reference ranges, since they vary from lab to lab and there are no standard ranges. Your result of 7.2 is a different unit that we, typically, see, so we'd have to know that, as well.
Wow - I can't imagine anyone being on Armour, which has T3 in it and not being tested for Free T3. In my opinion, that borders on malpractice.
Often when one is pregnant, thyroid hormone levels must be increased, because you have to provide enough of the hormones for, both, you and your baby until her/his thyroid is developed and produce on its own. Adequate thyroid hormones are essential for the growth and development of a fetus.
At 2.38, your TSH is on the higher side of the "new" (approximately 12 yrs old) range, which is 0.3-3.0, recommended by AACE and ATA, but labs and doctors have been very slow to adopt the range.
You should get the reference range for the Free T4 (if you can't get it from your doctor, call the lab that did the analysis) and insist that your doctor order Free T3 as well as Free T4, every time you have thyroid blood work, which should be monthly during pregnancy.

No ref range and no t3 testing, you'd think that would have been done but it wasn't. At the time I thought it would have been considering my t3 has been low in the past which is why I was put on armour thyroid. Currently taking 90 mcg dose every day which is what I was taking prior to pregnancy.

What is the reference range for the Free T4? Reference ranges vary from lab to lab and we need to compare your result with the range used on your report. The range is usually in parenthesis beside the result.
Did you not have a Free T3 test done? That's actually, the most important one. You should ask your doctor to order that test next time, alone with TSH and Free T4.
