Detailed Answer:
Hi Mr XXXX,

Welcome to HCM. Thanks for posting the question.

Once on treatment the TSH should be between 0.5 and 3.5 miu/ml. Her TSH is high. If she was taking Thyronorm 100 mcg regularly in morning empty stomach till now, she needs to increase the dose to 125 mcg. If she was not taking the medications regularly, continue with 100mcg for another 6 weeks and retest.

Hope I have answered your query. If you have any further questions I will be happy to help

With warm regards,
