What does the accuracy figure mean?
MARD is the average gap between what the sensor says and what a laboratory blood test says, as a percentage. A 10% MARD means readings are off by about 10% on average — so a true 7.0 mmol/L might show as anywhere around 6.3 to 7.7. Lower is better. Most current sensors sit under 10%; twenty years ago they were over 20%. No sensor is exact, which is why treatment decisions still get confirmed with a fingerstick when a reading does not match how you feel.

What works well
- About £18 a sensor cheaper than the Libre 3 Plus for the same fifteen days of wear
- Optional high and low glucose alarms
- Works with a reader as well as a phone, which suits people who would rather not rely on one
What to watch out for
- Shorter alarm range than the Libre 3 Plus, roughly six metres rather than ten
- Abbott has not published a separate accuracy study for the Plus sensor
Our verdict
The value choice in Abbott’s range. You give up some alarm range and the newest sensor hardware, and you keep the same fifteen-day wear for about £104 a month privately.
Common questions
- What is the difference between the FreeStyle Libre 2 and the 2 Plus?
- The Plus sensor lasts up to 15 days rather than 14, and is the version Abbott now supplies in the UK.
