Hi, I am new here, so I will encourage you to keep posting, and asking questions...this site has a lot of supportive people on it...
I'm still learning about the thryoid, and medicatins,and counts..
I do know that the eGFR if for kidney, as it the cretinine. An eGFR as it has been explained and I've read a number above 60 is good.
Another thing I do, is if I do not know what something is, I google it, and behold they have an answer...
Take care
pretty much you had the Hashimoto autoimmune thyroid tests and you tested positive. So in combination with the TSH of 8.61 your doctor is assuming you have Hashimoto hypothyroid autoimmune disease.
Please read up on the autoimmune Hashimoto thyroid disease and keep posting your questions. This can be difficult to understand right away and it can be a tough thing for the person experiencing symptoms to go through alone - not knowing.
