Rohlfing et al reported an equation for estimating the mean plasma glucose concentration from the hemoglobin A1c levels. The authors are from the University of Missouri.
Parameters:
(1) hemoglobin A1c in percent
estimated mean plasma glucose in mg/dL =
= (35.6 * (HgbA1c)) - 77.3
estimated mean plasma glucose in mmol/L =
= (0.0555 * (mean plasma glucose in mg/dL)) =
= (1.98 * (HgbA1c)) - 4.29
Performance: r = 0.82
