Question about thyroglobulin

Posts: 1

I know several people of posted information about the thyroglobulin level post TT & radioactive iodine. Will being on thyroid replacement (levoxyl, synthroid, etc.) effect this level? Basically I was wondering if I had to be off the replacement prior to checking the thyroglobulin level. I would appreciate any information.

I would ask your doctor, I know for me, We're trying to completely suppress both my Thyroglobulin and THS levels. But obviously I'm not a doctor. lol Sorry I wasn't much help :( But yeam for me I've had to be on my hormone replacements to get an accurate test, since I'm using the homones to control/suppress my thyroglobulin and TSH. When my bloodwork is done on when I'm on my hormones it gives us an idea of whether or not I'm on the correct dosage. - Hope that made some sense lol

My answer is exactly the same as Sally08's answer. You need to be on your meds to see if your numbers are where they should be.
