Accuracy and Glucose Testing Procedures

Stage	POC glucose testing procedures
CGM validation	POC glucose testing Q1 hour compared to CGM glucose Proceed to Q6 hour POC testing when 2 consecutive sensor-meter pairs approximately 1-hour apart meet either of the following criteria: 1)CGM < 20% difference from the POC when the glucose is >100 mg/dL 2)CGM < 20 mg/dL difference from the POC when the glucose is <100 mg/dL
Sustained use	Revert from Q6 hour to Q1 hour POC testing if: 1)CGM < 20% difference from the POC when the glucose is > 100 mg/dL 2)CGM < 20 mg/dL difference from the POC when the glucose is < 100 mg/dL 3)Revert back to Q6 hour POC testing when 2 consecutive sensor-meter pairs approximately 1-hour apart meet the initial validation criteria Obtain 1 time POC glucose if: 1)No glucose value appears on Android screen (due to signal loss, low/high measure) 2)Predicted low or low threshold alert 3)Signs and symptoms do not match glucose readings, particularly for hypoglycemia 4)Change in clinical status, such as intubation, hemodynamic compromise, or nutrition
