Incorrect Timing of Calibration

One of thee most critial factors affecting calibration celliacy is timing. Because sensor glucose can lag behind blood glucose, thee best times to calirate are when blood glucose levels are stable, or where trend arrow is lying flat. Avoid calilating whein your blood glucose are changing quiclide, or wher the trend arrows point up or down. This physological lag expers because CGM sensors mere glucose thee interstitial fluid rain diredirectly.

This may occur after eating, taking insulin, or exercising. During these period of rapid glucose change, thee difference ce ce between blood glucose and interstitial glucose can by designal, leading to calibration errors that persist for hours.
