Thanks to advances in technology, Continuous Glucose Monitoring (CGM) systems have seen many changes since the FDA approved the first one over 20 years ago. These advancements have revolutionized diabetes management and changed the lives of diabetes patients around the world.
Prior to the creation of the CGM, the primary method to check blood glucose levels was the use of a Blood Glucose Monitor. BGMs first arrived on the scene in the 70’s and served as the main and most reliable method to check and monitor levels.
Like everything else, technology just makes things better and Continuous Glucose Monitors have surpassed the ability of Blood Glucose Monitors. However, both continue to be used by patients and healthcare providers. It’s important to understand their differences first before comprehending how truly sophisticated diabetes management technology has become.
A Blood Glucose Monitor or Meter tests the concentration of glucose in the blood through a fingerstick to draw blood. Then uses a test strip that interacts with a digital meter to identify blood glucose levels. It is important to note that Blood Glucose Monitors measure glucose levels at a particular moment in time and focus on a single number.
A Continuous Glucose Monitor takes glucose readings continuously with a small electrode placed under the skin that is held in place by an adhesive. A transmitter attached to the electrode sends data to a separate unit or smart device and allows a patient to record and access valuable information and trends on a continual 24/7 basis. CGMs do not require fingersticks to measure glucose levels which makes monitoring easier and less painful.
While the first CGM may have arrived on the scene over 20 years ago, there have been many enhancements and advancements to CGMs since that time.
The Continuous Glucose Monitor Brands
First, it’s important to understand the market. There are currently four FDA-approved CGM systems on the market today. They are the Dexcom, Medtronic, Freestyle Libre, and Senseonics.
All four systems use a sensor that is inserted subcutaneously as well as a transmitter and receiver to allow for data collection. Each provide reporting that records and tracks activity to show trends and aid in overall diabetes management. When reviewing the various brands, there are, however, a few differences that help to distinguish between them, like price. Let’s take a closer look at each one.
Dexcom
The Dexcom is considered the pioneer in CGM systems. It uses its own software called Clarity and offers customizable alerts, smartphone app compatibility and voice integration through Apple’s Siri technology. Data can be shared with up to 10 followers and can be used in patients as young as two.
- ● Price1: $300 for the transmitter. $600 for the receiver. $80 per sensor.
- ● Sensor life is 10 days.
- ● Covered by most private and public health insurance plans and Medicare.
Medtronic
Medtronic is considered the leader in insulin pump technology, but also makes a CGM device called the Guardian Connect. Medtronic’s sensor can be worn on the abdomen or upper arm for up to seven days. A Bluetooth transmitter can send glucose readings to a smart phone app every five minutes. The Guardian Connect is also FDA approved and can be used in patients aged 17-75.
- ● Price1: $1000 for the transmitter. $80 for the sensor.
- ● Sensor life is 7 days.
- ● Covered by most private plans, but not Medicare
FreeStyle Libre
The FreeStyle Libre uses a flash sensor that allows the patient to be in control of their own readings. Using a handheld receiver or smart phone app, patients can hover over the sensor to get readings which can even occur through clothing. The sensor is also waterproof and can be worn while swimming or bathing. It’s also small and lightweight and can be worn for up to 14 days. The FreeStyle Libre also has its own software and offers remote data sharing with up to 20 people.
- ● Price1: $60 for the sensor scanner. $40 per sensor.
- ● Sensor life is 14 days.
- ● Covered by most private and public health insurance plans and Medicare.
Senseonics Eversense System
The Eversense system is the world’s first implantable CGMs. Its sensor is the size of a small twig and implanted in the upper arm. The Senseonics is approved for 90 days of wear here in the United States and even longer in certain European countries. Like the other CGMs, it also has a downloadable smart phone app for easier tracking and reporting. The Eversense system was on a brief hiatus and has recently re-entered the US market.
- ● Price1: $1400 for initial package which includes sensor, transmitter, adhesives, start guide). Then $200 to $300 for insertion and $300 to $400 for removal and reinsertion.
- ● Sensor life is 90 days.
- ● Covered by most private plans, but not Medicare
