After being diagnosed with hypothyroidism this year I urged by younger sister to go get tested even tho she is not really symptomatic. Her TSH has come back slightly elevated 8.05 (0.35-5.0) and her ft4 ok. However what has surprised us is the level of her antibodies at 501 (0-60). I thought mine was high at 117. Can anyone advise what this level actually means? She has her GP follow up appt next week.
Thanks for any advice
