Medical alert over glucose test strips
A specific brand of glucose test strips could produce false high readings, doctors and users have been warned.
A medical safety alert has been issued by the Medicines and Health products Regulatory Agency (MHRA) on behalf of Menarini Diagnostics UK about their GlucoMen LX Sensor test strips.
In a letter written to general practitioners, Richard King, the quality manager of Menarini, said: “Menarini Diagnostics has detected a few cases of inaccurate results obtained by some users of the GlucoMen LX Sensor test strips for blood glucose self-monitoring, used with the glucometer GlucoMen LX PLUS.
“An in-depth analysis has enabled us to identify incorrect storage of the vial after first opening as the source of possible overestimated results.”
It has been recommended that the vial should be closed immediately after each use as if it is left open to high environmental humidity for a prolonged period of time, the test strips may overestimate the blood glucose value.
The test strips must be stored in their original vial and the discard date should be written clearly on the label, counting nine months after opening.
Users who obtain anomalous values must repeat the test with a new test strip and if the results continue to be abnormal or not consistent with what they feel, they must contact their doctor before taking any other action.
