People with diabetes have been warned to check if they have a faulty blood glucose meter at home that could give a false reading and delay treatment.
Around 22,000 people are thought to be using either of two models of the OneTouch Verio meter that have a fault causing them to either turn off or give a false low reading if the blood glucose level is extremely high, the Medicines and Healthcare products Regulatory Agency (MHRA) said.
Manufacturer LifeScan has recalled the OneTouch Verio Pro with serial numbers starting with RA, RB, RC, RD or RE and the OneTouch Verio IQ with serial numbers starting with TA or TB.
The problem also affects all OneTouch Verio meters used only in healthcare settings, which have been alerted, the MHRA said.
It said the fault could mean diagnosis and treatment are delayed.
Those using the meters can contact LifeScan, which will provide a fully-working replacement free of charge. OneTouch Verio strips and other models of LifeScan meters are not affected by the fault or recall.
MHRA director of medical devices, John Wilkinson, said: “Extremely high blood glucose levels in people are rare, but if they do occur the person will require immediate medical attention.
“Protecting public health is our priority. If you have a Lifescan OneTouch Verio blood glucose meter, please telephone LifeScan on 0800 279 9118 (UK) or 1800 535 676 (Ireland) for a replacement.”
Diabetes UK spokesman Simon O’Neill said: “Blood glucose testing is an important part of diabetes management. People using these meters shouldcontact the manufacturer for a replacement but if they are concerned about their blood glucose readings, they should consult with their diabetes care team.”
