The Truth About Meters

blood glucose meters

There is no implied or expressed endorsement of any meter…it’s just a picture.

Last November I wrote a blog post about blood glucose meters.  I just assumed they were accurate, or at least provided numbers that were very close to my actual blood glucose level.  I really don’t think that is an unrealistic expectation since so many monitor their blood and make decisions on insulin doses based on the readings the get from their meter.  The numbers we get have to be close, right?

Well, not so much.  You can read my post from last November to get more information.

But, why am I re-visiting the topic?  Today I found that  some folks actually did a study on the accuracy of blood glucose meters. What they found pretty much validated what I wrote in november – now, there is research behind it.  Some meters are better than others in that they are able to consistently provide results that are within 15% of being accurate.  Some even do well at getting to within 10%!  Take a look at the chart.

Translation: If you get a number of 100, you are going to be somewhere between 85 and 115.  Some might be even more accurate than that, but the study did not reveal any.  The goal was to determine how often a meter got within 15%.   The best meters get within 15%, 100% of the time.

Does that sound a little confusing?  Yeah, it does.  The big take away for me in November, and now, is that the meter can generally tell me when I am lower, or if I am higher.  That’s about it.

You know, if I was injecting insulin into my body, this would drive me crazy.  It would be so easy to give myself too much, causing my glucose to dangerously drop.  As Diabetics we deserve much better than we are receiving.

You wonder why I don’t have any advertising on this site?  This is one of the reasons – products that do not perform as they should, but still fall within government standards – those set by the FDA.  If you think you deserve better meter accuracy that you are receiving, contact your federal representatives.  We do deserve better!  After all, we give our blood to these things.

You have to have to have the best weapons available to fight your War On Diabetes.  Currently, our meters are nowhere near the best.  It’s almost as if the meters and strips are being made by the lowest bidder…hmmmmm…could that be so?

We deserve better.  You deserve better.  But, even with meters that are not as accurate as they could be, you can still fight and win your War On Diabetes.  Lower is still going to be lower – and that is the goal.

As always, thank you for reading.
