According to MHRA, while using Accu-Chek Inform and Inform II blood glucose metres, the units of measure may change from mmol/L to mg/dL.

This might result in the user thinking that the blood glucose is higher than it actually is.

According to Roche Diagnostics, this problem was caused when metres with a nearly depleted battery were not docked in the charging unit for sufficient time to allow the meter to synchronise with the data management system.

The MHRA has asked the healthcare professionals using these devices to charge the metre immediately when the battery is low and to check the units of measure to ensure that it is displaying the correct units – mmol/L.
