Source: consumerguide.diabetes.org (verified 2026-08-01) · corroborated by singlecare.com. ADA's consumer guide gives the Guardian 4 spec table: 7-day wear, 120-minute (2-hour) warmup, checks glucose every 5 minutes, 'brief exposure only (splashes of water)' water resistance, no calibration required, MARD 10.6% (Adult) / 11.6% (Pediatric), sensor 1.50 x 2.60 x 2.00 in, approved ages 7+ but not for use during pregnancy, 6 ft transmitter range, insertion in the back of the upper arm. Medtronic's own support materials name the Guardian Connect app (separate iOS/Android builds) as the companion app, which also displays glucose data live on the MiniMed 780G pump when the sensor is used with that system. Medtronic and the FDA both confirm the Guardian 4 sensor's approval alongside the MiniMed 780G system on 2023-04-21. SingleCare states 'the average cash price of Guardian 4 Glucose Sensor is $2,478.3 per 3, 5 miscellaneous boxes,' i.e. a multi-box fill; no cleaner official per-box breakdown was found, so the total figure is reported as-is with this caveat.
