Monitor

[WendyB61]

Which BG monitor I do people find the most accurate please?

 

[Kaylz]

There really isn't such a thing as "most accurate" they all have to fit into regulations, they all have a 15-20% margin of error "allowed" xx

SD Gluco Navii or Spirit Tee2 are 2 monitors which many members use.
Most monitors have a certain degree of inaccuracy, and are best only used as a general guide to Blood Sugar trends!

Different meters suit different people. The Gluco Navii and Spirit tee2 have been found to be very reliable by members here.

Some brands make more use of the 15% (ish) allowable variation than others.

I happened to notice a paramedic using an SD Codefree the other day (which is the older version of the Gluco Navii) so the NHSis obviously happy with them.

Roche and Ascensia/Contour Next meters usually do well in bench tests. This is from a few years ago:

Are Blood Glucose Meters Accurate? New Data on 18 Meters

Results from the Diabetes Technology Society’s Blood Glucose Meter Surveillance Program identifies only six out of 18 meters that passed. Did yours make the cut?

The standard they should meet is

ISO 15197:2013​

A bite size info From diabetes.co.uk

• Within ± 0.83 mmol/L of laboratory results at concentrations of under 4.2 mmol/L
• Within ± 20% of laboratory results at concentrations of 4.2 mmol/L or more

I think it’s now 15% not 20%?

Blood Glucose Testing and Implementation of ISO 2013 Accuracy Standards – NECS Medicines Optimisation

All blood glucose meters must conform to ISO 15197: 2013, and manufacturers will no longer be allowed to supply meters which do not meet these new standards after 31st May 2016.​

​

These new standards are designed to ensure accuracy of testing and assurance that results are comparable to those produced by laboratory equipment. To be compliant results must be:​

​

• 95% results must fall within ± 0.83 mmol/L of laboratory results at concentrations of less than 5.6 mmol/L
• 95% of results must fall within 15% of laboratory results at concentrations of 5.6 mmol/L or more.
• The 2013 guidelines also now stipulate that 99% of readings must fall within zones A and B of the Consensus Error Grid for type 1 diabetes.

There are different numbers which are all correct. I think it's 15% for 95% of the time, and some larger number for 99% of the time (which may well be 20% though I think I've only seen a graph). Regardless, it's not that simple but I think you're right that 15% is the one to remember.

You are right Mike, thank you, not much is available for the standard my company is a member of the BSI and it doesn’t even list it, must come from American ansi
