Comparative StudyContinuous glucose monitoring in the management of diabetes mellitus.
Continuous glucose monitors (CGMs) measure interstitial fluid (ISF) glucose, and provide information about continuous glucose fluctuations that is not otherwise captured by intermittent blood glucose testing. CGMs may benefit patients having difficulty controlling their blood sugar or during initiation or monitoring of insulin pump use. CGMs require calibration with finger-stick tests and supplement, but do not replace conventional blood glucose testing. CGM values correspond to blood glucose values taken approximately 13-18 minutes earlier and may differ from metered readings.
