My neurologist ran an auto immune anti body test on me several weeks ago. When I went for my office visit today he told me the test were okay. When I got home and started reading the test results I discovered that my Thyroglob was <20 and the normal range is 0-40.

I was diagnosed with Grave's Disease and Hashimoto's in my 30's, drank the radioactive iodine which caused my to become hypothyroid. That's been 19 yrs ago and I am currently taking Armour Thyroid medicine.

Can anyone help me understand what this means? Internet searches are not helping me much.

Thanks.
