Hello and welcome to HCM,
It is evident from your history that you are suffering from diabetes mellitus
and you are not able to maintain your blood sugar levels.
HbA 1c is done to see the blood sugar control over a period of past three months.
A value of 6.1 suggests a fair control.
Elevated levels of T3 suggests hyperthyroidism
Alkaline phosphate is elevated in many conditions like liver
disease however, a single investigation is not of much help.
The entire function tests need to be done.
Monitor your fasting blood sugar and post prandial levels regularly.
Stay in touch with your physician/ diabetologist
Thanks and take care.
Dr Shailja P Wahal
