I have just got some blood tests back, ordered by gyno. I have only once ever registered Hashimotos antibodies (20 years ago), and never again (thyroid gland has now shrunk) She (as well as another doctor) insist that I don't have Hashimoto's, as I have under range antibodies. My daughter's thyroid is being slowly destroyed and has been told she has Hashimotos by her endo..with less than range antibodies . I am so confused..Do we have Hashimoto's without having antibodies (or well under range)???
