How Guardian Sensor 3 Works with Your Insulin Pump System?
The Guardian 3 uses subcutaneous interstitial fluid to measure glucose concentrations beneath the skin. Here’s the clinical process.
1
Glucose oxidase enzyme on the sensor reacts with interstitial glucose
2
This reaction generates a small electrical current proportional to glucose levels
3
The Guardian Link 3 Transmitter converts this signal to digital glucose data.
4
Wireless transmission sends readings to your MiniMed insulin pump display every 5 minutes
5
SmartGuard technology uses this data for automated insulin delivery adjustments
Important point!
Using medications containing acetaminophen, like Tylenol™*, fever reducers, or cold medicine, while wearing the Guardian sensor 3 can lead to incorrect elevation in your sensor glucose readings. The extent of inaccuracy varies based on the quantity of acetaminophen in your system and can differ for individuals. Always verify the label of any medications to confirm the presence of acetaminophen.

I couldn’t find sensors for my Medtronic 670G Pump after my previous Supply company misled me about insurance coverage. Their poor customer service made me switch to CGM Monitors.

I’m over the moon that I found CGM Monitors to order my Guardian sensors for my Medtronic 770G pump. Dealing with Medicare for insurance at this age is tough, but CGM Monitors saved the day. Forever grateful to them! 🙌😊

Medicare denied my request for Guardian 3 sensors before my Europe trip. CGM Monitors came to the rescue, saving me from three months without sensors and avoiding a $610 expense from Medtronic.
