Standard Deviation

[Deleted member 391597]

Hi all,

Does anybody know what the standard deviation should be with blood glucose control? I've been using the mysugr app which records this but I have no idea what I should be aiming for!

Thanks

The standard deviation figure gives an indication of how much variation there is in a set of results, A small SD implies good control.a large sd shows readings are all over the place. Not sure what 'figure' represents your target.

I usually use as a SD blood glucose levels between 80-120/130 (its the normal range for people withou diabetes só I think it's a good one)

 

[andcol]

think of it as the average distance all the samples are from the average

I havent time to enjoy the calculation but it will look like .......depending on which units you are using :
anything above or below the normal range will be a standard deviation of 1
any thing below the low range ie very low or very high or will be a standard deviation of 2 I bet it is about 2 using mmol

There is no answer to your question really...

Ideally, the lower your SD, the better (providing that you're sitting your personal BG target range).

Normally mysugr (and most monitoring apps) report the standard deviation in your measured units, In that context, what is usually recommended for type 1s is that you ideally want that value as less than 1/3rd of your average glucose level, as this generally indicates that you've not been swinging from low to high too much, and there is growing evidence that dramatic changes in blood glucose levels are as damaging as running constantly higher.

So for example, you might have an average of 6.6mmol/l and a standard deviation of 4.4mmol/l. This would indicate that you were experiencing a lot of variation in glucose levels.

You would also need to bear in mind that when based on finger pricking, standard deviation isn't as useful as people tend to test when they feel high or low, and this can skew the results.
