Is HBA1C test reliable?
In recent times, HBA1C test has been a more popular tool in diagnosing the diabetes which calculates the amount of sugar sticked to haemoglobin during its life span of 3 months.
My questions are,
1. Let's assume a normal person have had more sugary items and bad diet just before the test is done - let's say from week before or 3 days before the test is conducted, wouldn't it spike the readings and show false results?
2. After low carb diet for 3 months if HBA1C levels are normal then is the same person is no more diabetic?
3. Is a person is diagnosed as diabetic with one 7.4% reading of HBA1C alone?
Thanks in advance.

Hello there.
I can understand your concern.
For diagnosis of diabetes FBS, PPBS AND HbA1c all three are required.
The difference between a normal person and a diabetic person is that a normal person can maintain a given level despite the type of diet you have and a diabetic cannot maintain normal levels because he has lost the capacity.
Therefore yes HbA1c reliable.
Consult a diabetologist in person for further evaluation and management.
Best regards.
