Yes, blood work was done many times before and during Rad.
I don't know if it included thyroid tests. I asked via email but did not get a response. I'll make appointments and ask then if I dont get a response.

When I ask for a complete hormone panel, which tests should it include. If they don't want to do all of them which ones are most important.

Is it fairly simple to add vitamin deficiency and l-carnitine tests, just in case?

If I run into resistance, what are some good arguments that tests are needed. Should I bring them copies of studies...
