TSH level of 3.1 what does it mean?

FinnMaid

It means you're a bit on the hypothyroid side. If you have symptoms that sound like HypoT they probably are HypoT. You need further testing (FT4 and thyroid antibodies at least).

Hi,
l, agree with, Finnmaid but here in the UK you won't be diagnosed as hypothyroid until your TSH is at least 10.
Have you been invited back for another blood test in 3/6 months? some docs say 3months most say 6 months. Your TSH will need to be monitored regularly and if/when you go for your next blood test it is best to go early in the morning, that is when your TSH will be at it's highest.
