Regulator asks people to check their diabetes meters following false high readings

Posted on 10 June 2014

People with diabetes using a certain blood glucose meter are being warned after some experienced falsely high readings.

The Medicines and Healthcare products Regulatory Agency (MHRA) is asking users of Accu-Chek Mobile blood glucose meters to ensure they follow the testing instructions. This is because the meter may give false high blood glucose readings if testing instructions are not followed accordingly. 

Manufacturer Roche Diabetes Care states it has identified a small number of people using the strip-free Accu-Chek Mobile blood glucose monitoring system who have experienced falsely high blood glucose readings. This meter requires users to follow different testing instructions compared to other diabetes meters. If this procedure is not followed correctly an incorrect reading may be given even though the meter is working properly.

The manufacturer has issued fresh training and handling instructions which are available online.

John Wilkinson, the MHRA’s Director of Medical Devices, said: “People using this particular blood glucose monitoring device are encouraged to access the updated testing instructions at  www.accu-chek.co.uk/mobilepropertesting.

“An incorrect blood glucose reading can lead to people using the incorrect dose of insulin which, in some circumstances, could lead to an extremely low blood sugar (hypoglycaemia) and this may have serious consequences.

“People need a fully working blood glucose meter so they can get an accurate reading and, if necessary, seek immediate medical attention.

“Blood glucose testing is an important part of diabetes management. People using these meters should ensure they follow the correct operating instructions when using them.

“If people have any questions about their blood glucose readings they should speak with their diabetes care team. Or they can contact the Accu-Chek customer care line on 0800 701 000.”
