Variations in meters' readings

We've had considerable discussion recently about the accuracy of various meters. This is an article I found this morning online. It is by One Touch and offers some information on meters, readings, and consistency (or lack of) from meter to meter.

I've now used three meters and find all have different readings. My solution was just to choose one and use it consistently so that I can track how my BG changes w/r/t my other BG readings. It may not be the same as a lab, but at least I'm not confusing myself with the differences between meters.

Here is the site for the article. My apologies, but it did not come over as a live link. (James: I think I still need some more help with this process!)

NOTE: some of you have had difficulty with this link because when you use it, it looks like it goes to a blank blue page. If you get the blue page, you are in the right place. Scroll down for the content.

The secret is to pick one meter and stick with it,because for some reason they all vary,so stick with one meter and keep a log of diet and blodd sugars

I do agree! This article says that a 20% variation may occur between meters and the lab tests and still be in the acceptable range per industry standards. Scary thought! It also indicates that, because of the method of processing, lab results will always be higher. A metered test of 113 will give a lab result to 126 (diabetic).

Great post Carol, like you I use one meter as my main log, and only use 2nd meter as back up, and know the average difference between them.

Does simplify the process. I recently found with medicare that I was able to increase the number of tests/day and get the whole bunch for less than I've been paying. I miss the convenience of the One Touch Ultra's internal tracking system, but can do that myself for the $200 a month I'm now saving!

Yes it helps, which also shows how the aged and the underprivileged people are denied the proper supplies for the best treatment of our illness. Would make a great forum platform for someone to start.

Yes, it's a really mixed bag. For years, with private pay insurance through work, I had no copay, then $10/copay. The catch was that without needing insulin, I was limited to 2x per day, so I always bought extra.

When I was between insurance, it was over $110 for 100 strips. I'm doing this w/out meds, so I do test around each meal of the day. That was getting outrageous and I was at the point where I would have to stop.

It is a puzzling scenario.

Even taking insulin some idiot in the insurance office thinks twice a day is enough to check B/G. I am on SSD, and do not yet qualify for medicare, have to use medicaid. Unless I watch how scrips are written I can run short of supplies, if Doctor does not specify how many pen needles to use in a day the default is one, most days I need four, on the rare day it may take six as the dose must be split to empty one pen and finish up on new pen, hate to through thirty units of insulin it the trash over a twenty three cent needle.
PS How Wayne doing?

I bought him a plasic donut so he can sit more comfortably. Doc said if the tailbone was broken, it would take up to 2 months to heal. He is moving cautiously. We have gone out a couple time so he doesn't get to feeling to house bound.

Thanks for asking, Tom.

The file came through fine!. The link isn't made live till you post the posting

Caroltoo 2011-12-17 15:20:32 -0600 Report

Yes, I discovered that when I actually posted. I hadn't taken that step the other 4-5 times I've tried this.

If I am replying to a discussion post or replying to a reply I usually post it and then check the link to determine if it goes where it ought. Sometimes they don't then I can highlight & erase that link and try to find it again and repost it and make sure it goes to the site I want.

So frustrating when a link is not working!

Caroltoo 2011-12-18 12:35:10 -0600 Report

Yes, I noticed last night that the link wasn't working properly. Is there a way to edit a discussion or would I just have to enter the corrected link in the "comments" section?

jayabee52 2011-12-18 16:50:39 -0600 Report

you could put the new link in a discussion reply but the downside to that would be that the newer replies would push that link lower in the discussion que. Some have brought the link to the top by periodicly reposting the correct link as a new reply to the original post. Others have gone to someone like John Crowley and through him ask the tech people to insert the right link where the broken link was.

Caroltoo 2011-12-18 17:16:45 -0600 Report

OK. I will see if I can find it again and add it in. Tech folks are so overloaded right now, I don't think should be high priority.
