Brief summary

The purpose of this study is to characterize the impact of acetaminophen ingestion on the performance of the Guardian™ Sensor (3) (i.e., C algorithm and Zeus algorithm) in subjects age 18 - 80 years.

Detailed description

The study is a multi-center, prospective, study without controls. The purpose of this study is to characterize the impact of acetaminophen ingestion on the performance of the Guardian™ Sensor (3) (i.e., C algorithm and Zeus algorithm) in subjects age 18 - 80 years.

Interventions

DEVICEGuardian™ Sensor (3) connected to a Guardian™ Connect Transmitter. C sensor algorithm applied retrospectively to raw sensor data.

Characterize the impact of acetaminophen ingestion on the accuracy of Guardian™ Sensor (3) when C sensor algorithm is used.
