Coded wrong!

[Cinnabon]

Last week I noticed I had coded my meter wrong, of course I had used up the whole vial. How off can these results be?:whistling

I've done it on purpose with no unexplained variance in results. So I often ask why we have to bother?

[Cinnabon]

Thanks Duck. I had not noticed and went through it like nothing, till I went to throw it out!:egg:

not going to be off by much.

I've done the same thing duck did, coded wrong on purpose to see what would happen, not much : imHo

[JediSkipdogg]

Depending on how close the coded amount is to the strip it may or may not matter. I've had it coded wrong and had it been off quite a bit. I've also had it be off not that much. It's really hard to say and even harder to say wiht the 20% variance meters already have.

I think you'll be ok, Cinnabon...I too, have forgotten to change the code. Sometimes, I've noticed no difference, while others, it's been quite off. Usually, if/when it's been off, I just check with another meter.

I disagree with my esteemed co-posters. I've run tests on Lifescan meters to see how far off the results are. In a nutshell, the more numbers you are off by, the greater the error, until it reaches dangerous proportions. if you are off a few numbers, it's neglible. If your meter isn't a Lifescan, than I can't answer your question.

I've done the same thing and had identical readings with the same sample and different codes.

Cinnabon,

You didn't state by how far off your coding was, nor did you state the brand or model of your meter, so it's difficult to answer your question!

With my Freestyle meter, I've found the results to vary from one extreme end to the other by 20%.

Best way I can state it would be think of a bullseye. If you code the meter it will be a bullseye. If you don't it will still be accurate but not a bullseye more or less.

OUT!

You just brought up old reminders from high school biology, where we were taught the difference between accuracy and precision. *sigh* Old lovely memories! :marchmell

I sometimes forget to change the code on a new vial of strips. I use the Lifescan UltraSmart. Never had any problems...

I've forgotten to change the code a few times and once I realize it, I'll try another blood test and get very similar results to the one with the incorrect code.
