These meters have an incorrect unit of measure, and they display glucose results in mmol/L instead of mg/dl. This could cause a lower than expected glucose reading.
You can check if your meter is affected by calling 1-866-236-4518 or going to the website at http://www.niprodiagnostics.com/product-notice. You’ll just need the serial number from the back of your meter.
The manufacturer will be replacing the meters free of charge.
If you have any questions, you can find more information in the FDA bulletin here.
