Lifescan issue warning over blood glucose meter

On rare occasions, some users of the OneTouch Ultra Meter have experienced a change in the unit of measurement of blood glucose readings from mmol/L to mg/dL.

The unit of measurement change can occur when the meter is dropped while in use or when the battery is changed with the meter on.

While it is extremely rare, this kind of change in unit of measurement from mmol/L to mg/dL could lead the user to think that their blood glucose result is high.

This is because test results expressed in mg/dL do not contain a decimal point and are 18 times higher than the same results expressed in mmol/L.

For example, a result of "6.0 mmol/L" would display as "108 mg/dL," which might be misinterpreted as "10.8 mmol/L." This could potentially result in a user altering their treatment regimen, such as injecting more insulin than is needed.

LifeScan will be replacing OneTouch Ultra Meters (as well as the no longer manufactured InDuo and PocketScan Meters) with a OneTouch Ultra2 Meter free of charge. The company will be communicating with patients, healthcare professionals and pharmacies about the replacement programme, which will begin in early 2007.

LifeScan will announce details of the OneTouch Ultra meter replacement programme on their website in January 2007.

Cathy Moulton, Care Advisor at Diabetes UK said, "Whilst you wait for a replacement meter, please continue to use your current meter.  

"Keep a close check on whether it is reading in mmol/L units of measurement each time you test your blood glucose.  Also if you feel you may be hypo, it is vital you that you retest." 

If your meter displays mg/dL, contact the LifeScan Customer Care line immediately on 0800 028 8039 (UK) or 1 800 535 676 (Ireland) for assistance.If your meter displays mg/dL, contact the LifeScan Customer Care line immediately on 0800 028 8039 (UK) or 1 800 535 676 (Ireland) for assistance.

How to Check Your Meter's Unit of MeasureHow to Check Your Meter's Unit of Measure

Each time you turn on your meter, the unit of measure will appear on the display with the symbol. The unit of measure will also appear under every test result.

If the meter is set to the right unit of measurement, "mmol/L" will appear on the display. The test result will include a decimal point. In this case, continue to use the meter while you wait for a replacement.

If the meter is set to the other unit of measure, "mg/dL" will appear on the display. The test result will not include a decimal point.  In this case, do not use the meter and call LifeScan customer care line 0800 028 8039 (UK) or 1 800 535 676 (Ireland) immediately for a replacement meter.

No other LifeScan Meters are affected by this issue, including: OneTouch® UltraEasy, OneTouch Ultra2, and OneTouch® UltraSmart®.
