Dexcom G7 glucose monitors face user complaints over inaccurate readings despite meeting industry standards

Some users report inaccurate readings from Dexcom's G7 continuous glucose monitors, despite the device meeting industry accuracy standards. Users have filed lawsuits and shared negative experiences online, citing erratic readings. Dexcom acknowledges sensor variability but maintains overall device accuracy, attributing some issues to a now-removed manufacturing component. The discrepancy highlights how marketing metrics like MARD may not reflect real-world performance, leading to calls for more standardized testing and clearer user expectations.
