Hello sir/mam,i am a mbbs student. in october 2020 i had hyperthyroidism, anti
tsh ab test was negative, tc99 uptake scan was negative for graves. After 3 month of carbimazole hormones became normal, now in August 2022 i went for a routine
thyroid profile. Tsh is in range but its on lower border so i think it will reoccur. Sir why is this happening again as grave was not present, please advise me. I have attached latest thyroid profile photo. Thank you. Have a good day
