The earlier report of fasting blood sugar and PP sugar levels does denote diabetes
but the subsequent report of blood sugar levels are normal even without medicines.
It means either the earlier report was wrong or the person had started restricting the diet and then subsequently got the reports normal.
In any case these reports should be checked again after a gap of 15 days to actually look for the status of patient.
As far C - peptide levels are concerned,they are normal and it's normal level indicates that you are type 2 diabetic if a person is diabetic.
Neutrophils are definitely very high and indicates presence of infection especially if the person is having fever
Since there is strong family history of diabetes ,she should be very vigil regarding her diet,weight and do regular exercises.
For her best would be to keep herself in the required range of BMI.
