    Hba1C estimates on apps that you enter blood glucose data into tend to underestimate Hba1C levels, mainly due to people generally not testing during the post-prandial spike that many people get, and also due to the tendency to test more as you are going low. Although app manufacturers try and counter this a bit with some smarts in the algorithm they use, it's really only as good as "data in, data out".

    My estimated HbA1C from MySugr was accurate but I also input numbers from when my blood glucose is high.

    Ok cheers
    I put in any reading I do so fasting , pre meal and 2hr post
    I also test 1hr with a few more carb heavy meals , so fingers crossed it will be around the right area.

    I dont have my test for around a month so will know more then.

    All

    Just looking for further thoughts on the My Sugr app/correlation to HbA1c.

    Time is ticking and anxiety brewing as I near the time when I have my 3 month follow up blood test.

    This time around I was looking to understand more around Standard Deviation.

    Both my overall average BG is consistent day to day /week on week as is my Standard Deviation. I am just keen to understand what is the "good " criteria for "Standard Deviation" and it's significance if any on the accuracy of the HbA1c.

    I have this in my notes, but unfortunately the link no longer works.

    "You can use the standard deviation to look at your overall blood sugar control, or to check on specific times of day such as before breakfast. Just use the rule of thumb developed by Dr. Irl Hirsch, an endocrinologist at the University of Washington in Seattle. His guideline is that the standard deviation multiplied by two should be less than the average blood glucose number." https://www.bd.com/us/diabetes/page.aspx?cat=7001&id=14131 "

    Then there is this old T1 thread
    http://www.diabetes.co.uk/forum/threads/standard-deviation.40339/

    and if you Google there are quite a lot of articles.

    I've always worked to standard deviation should be no more than a third of average glucose levels. That works okay for me!
