Abstract

The proportion of sequential HbA1c exceeding critical difference (diagnostic yield), where it is considered clinically significant change, was calculated for different testing intervals. 12% and 26% of repeat HbA1c exceeded the critical difference before 30 and 90 days testing intervals, respectively. Repeating HbA1c within 4 weeks has poor diagnostic yield and should be avoided.
