Is thyroid test part of routine blood work?
A simple blood test for thyroid stimulating hormone, commonly referred to as TSH, is the first step in screening persons for thyroid disease, along with T4 as well as T3, other aspects of what we refer to as a thyroid profile.
Are there other blood tests to check thyroid?
Six other blood tests. That’s what you’re missing. Yes, TSH and T4 are important in the big picture of thyroid health, but without the other 6, MANY thyroid conditions (and other reasons for your symptoms) often go undiagnosed.
