The difference between sensor glucose and blood glucose

This resource explains how sensor glucose readingsmeasured in the interstitial fluid under the skindiffer from traditional finger-prick blood glucose values, noting a typical lag of 2.4 to 4.6 minutes between them. Discrepancies are especially noticeable during rapid glucose changes like after meals or exercise, yet when levels are stable, both readings align closely. Importantly, the FreeStyle Libre system is accurate and safe for insulin dosing based on scanned sensor readings.
