Hi Elliebee, I'm sorry your post seems to have been missed. I'm not on the forum much these days though as you know we do have several other hypothyroid members, but I guess no one has been around. I'm sorry to know your TSH has increased quite a bit, but I think your GP is probably right that your Thyroxine dose needs to go up now. No harm in checking the other bloods you asked for, but please don't be afraid to up your T4 dose as 50mcg is pretty low & often only used as a starting dose with the knowledge we are very likely to need more for the longer term. If doubling to 100mcg in one step feels too daunting you could perhaps discuss with your GP going to 75mcg for a few weeks & retesting.
I hope things go well for you.
