Hello, thanks for the query. With treatment (on 25 mcg per day of levothyroxine) tsh should be around 3 to 4 mu/l. Since it is 8.3 mu/l means your hypothyroidism is not in control. There is a need to increase the dosage by 12.5 mcg per day, then check tsh again after 6 weeks to see if desired level has been achieved. If you have any questions please do come back. Thanks,
