Thank you for choosing DoctorSpring.
The profile is suggestive of Graves' disease! You have taken Carbimazole for over a year! The profile of Dec 2013 shows uncontrolled thyrotoxicosis, which means, if you have been on regular carbimazole in good dose, you will require radioablation! You may try carbimazole at the dose of 30 mg daily for 3-6months, and see if it remits, and then consider radio Iodine treatment, if not willing at present.
Hope this helps
Feel free to ask followups

I guess the medical readings taken in december 10th was wrong. I did another check today from another lab. The readings are as follows
Serum T3 : 2.05 nmol/L
Serum T4 : 15.74 ug/dl
Serum TSH : 0.05 uIU/ml
I have been taken two tablets of carbimazole(5 mg) for almost an year now. So what do you suggest that I do at present?
I suggest that you take two tablets of Carbimazole 10mg every dayand repeat TSH and T4 test after every 2 mths for next six months. You can reduce the dose by 5mg /day once the TSH becomes normal or higher than 5 mIU/l. If the profile continues to show low TSH even after 6mths, you can consult for RadioIodine ablation treatment.
