I have used the Medic Alert bracelet since 2008 when diagnosed with Factor V Leiden – latest update in 2022 with MG diagnosis. I have the QR code stickers on my fridge & in my billfold – gave serious thought to getting a bracelet with the code but decided that anyone could read this code if they scan with a phone & have my medical info (lots of info). I would rather have emergency personnel call the number on bracelet if they have questions about the info in my bracelet. I don’t go away from home without my Medic Alert bracelet.
