Regulator asks those with diabetes to store home use blood glucose test strips correctly

Storing home use GlucoMen LX Sensor test strips incorrectly, especially in high humidity, can lead to falsely high readings.

GlucoMen LX Sensor test strips device

Anyone using the GlucoMen LX Sensor test strips to monitor their blood glucose levels must ensure they immediately close the vials properly after using them especially if they store their strips in a humid environment. Not doing this could expose the test strips distributed by Menarini Diagnostics UK to high humidity, which could lead to a reading that is higher than it should be.

People are advised to follow these 3 steps:

  1. Close the vial securely after using the strips
  2. Store the test strips in their original vial
  3. Write the discard date on the vial label – this is 9 months after you first open the vial

John Wilkinson, MHRA’s Director of Medical Devices said:

It is vital that people check that their vials are closed properly according to the instructions for use.

Leaving strips exposed in high humidity may result in falsely high readings, which could lead to them taking an incorrect dose of medication.

We continue to encourage people to report any issues involving medical devices to the MHRA via our Yellow Card Scheme.

Pav Kalsi, Senior Clinical Advisor at Diabetes UK, said:

When using any diabetes medication or equipment it is important to always follow the manufacturer’s instructions carefully, including details of how to store them correctly. This is necessary in order to achieve reliable results.

Users should contact their healthcare professional if the result is outside their normal range.
