hba1c normal range
HbA1c results in the UK have usually been aligned to the assay used in the Diabetes Control and Complications Trial (DCCT), expressed as a percentage (DCCT-HbA1c) - non-diabetic 'normal' range being 4-6%.ormal levels (laboratory normal 'range') will differ depending on whether HbA1 or HbA1c is measured, and the method used-use your laboratory's reference range (EDTA (FBC) bottle).
