    I have just carried out a blood sugar test with my Libre sensor and it shows 3.9 in the colour green. How is this possible? It should be in red! I’m concerned that my sensor is not functioning properly. Any suggestions? My low blood sugar number is 5.6 mol?

    I was taught at diagnosis that below 4 was hypo. According to my insulin pump, below 3.9 is hypo. I always treat below 4 results. You can't teach an old dog new tricks!;)

    You can change the green area settings. By default it is set between 3.9 and 10mmol

    I once went down the rabbit hole of trying to determine what exactly the definition of a hypo is.

    This site says

    Wikipedia says

    https://www.diabetes.org.uk/guide-to-diabetes/complications/hypos says

    The U.S. Department of Health and Human Services (An official website of the United States government) say :

    But apparently the Europeans don't agree with that definition because the document that they link to actually says
    (emphasis is mine)

    The freestyle app seems to use below 3.9
    from https://www.freestylelibre.co.uk/libre/discover/using-your-meter.html

    And just when you think you can conclude that it is either below 4.0 or below 3.9, and that there wasn't really much difference, then along comes our very own NHS !

    Yeah, I went down this rabbit hole myself and found pretty much the same as what you found. My reasoning for going down that Rabbit Hole was I switched Doctors, and the Doctor asked me "How many Hypos have you had recently?" and I was like "Well, depends what you mean by Hypo." and he said "3.5 and below" which was the lowest I'd ever heard of, and I had to go through my Metre to check, as my previous Doctor had always said 4.0 and below.
