Locations for Inserting Glucose Sensors

Shown here are the best body areas (shaded) for sensor insertion:

Note: Clinical trials of sensor accuracy have been based on sensors inserted in the belly area. Sensor performance may differ when other insertion sites are used.

Glucose Sensor Insertion Site Guidelines

Avoid inserting the sensor:

  • Into the 2-inch (5.0 cm) area around your belly button
  • Where your body naturally bends a great deal
  • In areas where clothing might cause irritation (for example your beltline)
  • Where you have scarred or hardened tissue or stretch marks

For Enlite sensor, your sensor should be at least:

  • 2 inches (5.0 cm) away from your belly button
  • 1 inch away from your insulin pump infusion site
  • 1 inch away from any other insulin needle injection site (syringe, pen)

For Sof-sensor, your sensor should be at least:

  • 2 inches (5.0 cm) away from your belly button
  • 2 inches (5.0 cm) away from your insulin pump infusion site
  • 3 inches (7.5 cm) away any manual insulin injection site
