Fasting levels are not a good predictor or necessarily a good indication of HbA1c as the fasting measurement is a snapshot of blood sugars at one specific time A1c gives a value for the average BS over several weeks and will be effected by levels between the individual tests you may have done.
Remiss of me welcome to the club.
Diagnosis of Diabetes normally requires two A1c tests showing diabetic levels interspaced by several weeks.
So can I monitor HBA1C at home ?
Thanks
