What does LO mean when it appears after users scan the reader over the Sensor?

If LO appears on the Reader when users scan the Reader over the Sensor it means the reading is lower than 20 mg/dL.  Users can touch the message button for more information.  Users should check their blood glucose on their fingertip with a test strip. If users get a second LO they should contact their healthcare professional immediately.1
