A1C low but Fasting blood Glucose above 100

Hi,
This is for one of my friends..
for the last 5-6 years A1C is on the lower side below max being 4.5 but Fasting blood Glucose above 100 ranging between 100 and 115.
Fructosamine test have been done couple of times and they were also with in range all the time.
The other medications they take is for Epilepsy (earlier Tegretol and then Lamotrigine for the last couple of years.
Their Hemoglobin also has been low below 13 for the last couple of years.
Is this normal or Is there anything to worry?
-Thanks
