Hemoglobin A1c and the Estimated Average Glucose
Conclusions
July 2009
In conclusion, the optimal diagnostic criteria for diabetes are still being debated. Hemoglobin A1c has recently been endorsed by clinical groups for diagnosis of diabetes using a cutpoint of 6.5%. Reporting of the eAG at this time is still controversial and will vary from laboratory to laboratory depending on the preference of the physicians, pathologists, and endocrinologists.
