Correction Factor Calculation

[JohnBont]

Hi everyone

Hope you can help. I understand to calculate a correction factor with novorapid in a type 1 diabetic you add up all the insulin amounts in a given day and divide this
figure into 100. I also realise to reach this figure you should use the calculation over a number of days. My question is do you include any correction factor insulin in the daily total or do you ignore these.
For example if I take +2 u correction at breakfast then 6u for the actual breakfast do I then add 6u to the total daily insulin or 8 u?
Thanks
John

I’d add 6 units @JohnBont unless the 2 unit correction is an habitual thing.

Thanks for your reply Inka, much appreciated.

I’ve only ever hear of these suggestions (100 rule, 500 rule) as using Total Daily Dose - so a total of all doses including basal, meal, snacks, corrections etc.

Of course there are also 150 and 300 variants… and they are really only a guide / suggestion as a starting point.

Hope you find and tweak a new correction factor that works well for you 🙂

I just work on the 1 unit will drop me about 3mmols suggestion I was given at diagnosis but if I am above 10 I will need a bit more. I have never had to correct for anything huge but if I did I would probably underestimate and bring it down in stages.
I am the same with ratios. If I stick to low carb then my 1:10 carb ratio which was suggested at diagnosis is never going to be too far out and 1;10 seems to work pretty well and then I just add on 1.5-2units in the morning for DP/FOTF. To me these are easy numbers to work with that don't require any great calculation. I might actually be 1:9 or 1:11 but I am not really bothered in finding out because my carb estimation isn't that accurate either, so 1:10 will get me close enough since I am only having 20-40g carbs per meal.
I find it quite surprising that people are so precise about this stuff but I guess it matters once you get into bigger numbers.

I tried it.
I took 1 unit of insulin when my levels were around 8 or 9. I ate nothing and did not exercise for 4 hours. Then checked my levels. I use the difference between my starting and ending level as my correction factor.

I had previously done a basal test and had no bolus on board so was confident it was only the correction dose affecting my levels.

@rebrascora I'm the same as you - 1 unit will drop me 2mmols but my DSN has said to only correct if I'm over 10mmol.
My ratio is 1:10. I don't do low carbs but I do do my best in counting them as best as I can.
If I feel I need to at times I just tweak things here and there.
My 2mmol correction has been the same since 1992! My 1:10 ratio changed to 1:15 and 1:05 but then I always end up back on 1:10
