Blood tests - TSH

[Char0187]

Hi, new here never posted before so not sure if this is in the right place but wondering if anyone knows anything about THS levels in pregnancy?

My 1st trimester THS results were 2.8 which my midwife thought was too high. Went to the doctor and he said they were fine. My 2nd trimester results have just come back as 3.6 which a different midwife has told me is too high again and sent me back to GP. Appt. on Friday.

Why are the midwives worried but not the doctor? Is it anything to worry about? Thanks for any help!

Hi, are you diagnosed hypothyroid? If so the NICE advice is that TSH should be below 2 during pregnancy. I think lots of GPS are unaware of this advice. A friend recently got very short shrift for bringing TSH levels up only to be called back later by sheepish GP who'do subsequently read NICE's clinical knowledge summary and thought better of brushing her off.

If you're severelyunder-replaced with thyroxine, in extremis, it can cause a range of pregnancy complications - don't panic but don't just accept what you're told either.

Hi, i have high tsh but now on thyroxin for underactive thyroid. In theory in tsh in pregnancy should be kept below 2.0 or 3.0 depending on who you speak to. The midwife was right to refer you to gp but don't panic. High tsh can cause problems in pregnancy but not at your levels- that said gp will probably want you to take thyroxin to get your tsh down a bit and ensure it doesn't get higher. You may find you have to have extra blood tests and consultant visits to make sure your tsh doesn't continue to go up but I very much doubt it will otherwise affect your pregnancy.
Thyroxin is an easy drug to take, no side effects and safe in pregnancy.

Hi, thanks for the replies. It seems the doctor didn't know about the new guidelines but all sorted now. Thanks again!
