The Dexcom G7 may show readings 50 or 60 points higher than fingerstick measurements due to several reasons:

1. Sensor's First Day: Newly inserted sensors may show larger differences, which usually decrease over the first 24 hours.
2. Pressure on Sensor: If something is pressing on the sensor (e.g., lying on it), it can affect readings. Removing the pressure can help.
3. Rapid Glucose Changes: Blood glucose changes before interstitial fluid glucose, so fast changes can cause differences between meter and sensor readings.
4. Fingerstick Issues: Inaccurate fingerstick readings can occur if hands are not washed properly or test strips are expired or used incorrectly.

These factors can cause temporary differences between Dexcom G7 and fingerstick readings.

1 • Welcome Thanks for choosing the Dexcom G7 Continuous Glucose Monitoring (CGM) System (G7)! Using this medical device, you'll see your glucose readings on your display device just by wearing a tiny sensor! Here are some of the benefits of using G7 to manage your glucose: No more fingersticks: G7 allows you to make treatment decisions without fingersticks.
Page 9: New Since G6
This G7 User Guide introduces you to the display device screens, leads you through making treatment decisions, and shows you how to move to your next sensor session. Each sensor session lasts up to 10 days, plus a 12-hour grace period at the end.

Page 13 G7) is a real time, continuous glucose monitoring device indicated for the management of diabetes in persons 2 years and older. The Dexcom G7 CGM System is intended to replace fingerstick BG testing for diabetes treatment decisions. Interpretation of the Dexcom G7 CGM System results should be based on the glucose trends and several sequential sensor readings over time.
Page 14 Where to insert — arm or buttocks: Don’t wear it on other sites as it may not work as expected. If you wore G6 sensors on your abdomen, wear G7 sensors on the back of your upper arm. Children from 2 to 6 years old can also choose their upper buttocks.
Page 15 Your glucose alerts sound and display information by default even when your volume is low or muted. Quiet Mode (Vibrate): When this setting is enabled all your Dexcom G7 CGM System alerts will vibrate. Your Urgent Low Glucose and technical alerts will still escalate to sound if not acknowledged.
Page 16 Portable radio frequency communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 12 inches to any part of the Dexcom G7 CGM System including cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment could result.
Page 17 Before insertion and during your sensor session, don't apply insect repellent, sunscreen, perfume, or lotion on your insertion site or sensor. This may cause the sensor to not stick well or could damage your Dexcom G7 CGM System.
Page 18 If you do, use your BG meter for treatment decisions until you leave the security area. This is because the Dexcom G7 CGM System hasn’t been tested with every x-ray and security scanner and you may not be able to bring a display device.
Page 19 However, with the Dexcom G7 CGM System, you can take a standard or maximum acetaminophen dose of 1 gram (1,000 mg) every 6 hours and still use the sensor readings to make treatment decisions.

Page 145 Hypoglycemic and hyperglycemic alerts Low and High Glucose alerts The ability of G7 to detect high and low glucose levels is assessed by comparing sensor readings to YSI values at low and high blood glucose levels and determining if the alert may have sounded. G7 and YSI values were compared by pairing the sensor reading and the YSI value within before or after 15 minutes of each other.
Page 146 For example, if you set the Low Glucose alert to 70 mg/dL, how often will your G7 alert you if your blood glucose goes below 70 mg/dL? Based on results for pediatrics in the G7 Study (Table 5-B), when your blood glucose goes below 70 mg/dL, you can expect your alert to sound approximately 90.4% of the time and not to sound approximately 9.6% of time...
