So I’m special and managed to forget my test strips when left the house this morning. Of course my Dex was supposed to be calibrated around 11AM. It’s still reading for me but keeps popping up the “enter BG” message every half hour or so. Does anyone have any idea how long it will continue reading my sugars before it refuses to tell me where it thinks I am? I’ve only got another 2 hours left of my work day and I’m hoping it will hold out. I was just wondering if anyone had done this before and how long they’d lasted? Thanks for letting me know!
