It is usually the 25 OH Vitamin D level that is measured.
The 1,25 di OH is not often measured, though it is a good idea. The 1,25 di OH is the active form.
Most docs will order the 25 OH test.
Ask for a vitamin D test if you haven't had one.
I think it's called a D-25 test.
vitamin D, 1,25-dihydroxy is how it is listed on my test.
Ask for a TSH, A Free T4 ,and a Free T3. Skip the Total T4 and Total T3 tests. They are not so good.
If you want your antibodies checked, ask for a Thyroid Peroxidase antibody test (TPOab), an antithyroglobulin antibody test (TGab), and a TSI test, if you think Grave's may be involved. TSI is thyroid Stimulating Immunoglobulin, and is found in Grave's patients.
I agree I would have you PC run everything and then send copies to endo. Yes I would also have your Ferritin, B12 and Calcium checked if it has been a while along with the thyroid test you have listed.....TSH, Free T3 and Free T4....possibly antibody tests again to see where you stand.
