I had some thyroid testing done in May by my primary care doctor because my symptoms suggested possible hypothyroidism. The TSH was high and my doctor referred me to a reproductive endocrinologist because I’ve been trying to get pregnant for a year and she suspects my thyroid may have something to do with it. The fertility folks ran a TSH as part of my bloodwork, and it’s still high, so now they’re asking me to go back and get a full thyroid panel done. What is the rationale for repeating thyroid peroxidase antibody and antithyroglobulin antibody so soon after my previous tests? The T3 and T4 I can see changing over time, but the antibodies wouldn’t be different two months later, would they?
I asked my nurse that question via email and she responded “Please repeat. Our bodies can change.” Besides being somewhat condescending, it’s unhelpful. She knows I’m a med tech, but she’s talking to me like I’m a fifteen-year-old who doesn’t know what hormones or antibodies are.
I’ll repeat the tests, because I don’t want to be difficult and have them drop me for being a noncompliant patient, but I hate to be racking up extra testing costs and extra holes in my arms just because it’s the usual progression of testing and they make everyone do it.
