Meter and test solution madness
 
Hi All,

Meter 1: Relion Micro
Meter 2: Relion Premier compact
Test solution: Arkray Assure Dose Control Solutions 500006

Every new box of test strips I open up, I like to run through my test solution. Saw something weird (meter #1). The 80 mg/dL was consistently comes out as 88 or 89. So I called ADW and asked them about it. They said the solution had been opened for too long. So I order another set. 88. Hmmmmmm.

I asked Arkray about it and they said "no longer supported" and very graciously sent me a free Relion Premier Compact (meter #2). Okay so testing that against my old and my new solution. Test 1: 118; test 2: 115. Huh??? IS sugar water not sugar water?

And ADW said the FDA allows the meters to be plus minus 15%; Arkray told me the FDA allows for plus minus 25%. AAAHHHHHHHHHHH!!!!! I WANT PLUS MINUS 1% !!!!!!

Oh and get this! Both meters measured the same blood droplet (from opposite ends so as not to mix reagent) at 91 and 92.

DOUBLE AAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHH !!!!!!!

What in the world is going on and what actually is my freakin' blood sugar??????

Many thanks,
-T

p.s. looked at "Diagnostics Direct 7314 Contour Next Normal Control Solution, Level 2, 2.5 mL " ad their test solution is rated 95-120. Useless !!! see https://www.amazon.com/ask/questions...dp_dpmw_al_hza

This is a concern that comes up at times.

This variability should not keep you from using your meter as a guide to your blood glucose levels. Most people cannot feel a difference in BG levels that is much larger than the 15% difference that is allowed in meters for personal use.

I've concluded personally that measuring blood glucose is like measuring the temperature outside: there are many variables (few of which we can control) and we have to be at least a little comfortable accepting one figure as accurate and actionable in the presence of many variable local measurements.

The "official" temperature where I live is measured either at the airport 15 minutes from my home or at the National Weather Service office about 30 miles away. I have a thermometer outside one of my windows that rarely agrees with the temperature at either location. But unless an oncoming storm is making temperatures change rapidly, a quick mental average of the different readings gives me an accurate-enough number to grab a jacket or open or close the windows before I go out.

In the absence of other symptoms of hypo- or hyperglycemia, I'll take the reading I get from my meter as "close enough" and proceed on that basis. I know I'm more permissive than some but I see diabetics manage well on BG levels that vary far more than 15% that I make myself okay with the numbers my meter displays. As much as I'd love to get one real number out of my meter at any given time, that's not the current state of the technology. I make myself be okay with that.

I am looking to find out if my test solution is accurate or not or if it is my meters that are off.

Must the test solution tied to the meter or can any test solution be used?

Basically, if I could do a calibration test to see what my meters say against an accurate standard.

This is extremely important to me at the present time as my eye doctor (a T1 diabetic) found evidence of minor bleeding on the back of one of my eyes and he thinks it is being caused by excess blood sugar. I am currently under treatment for this problem and I need to know EXACTLY what my blood sugar is, not a guess.

By the way, congratulations on your A1c. Don't get too happy though, A1c is plus minus 50% and a really, really sloppy test. So sloppy that I do not do this test. If ever needed again, I will do the fructosamine test, which is a lot more accurate. In the mean time, I test my blood sugar every morning.

One of the best explanations I read on how to use the testing solution was given by one of our members a couple years ago.

Meters are rarely "off". Never had one that actually was. So that part of the equation doesn't concern me. The only other variables are test strips, temperature, human error and blood homogeneity.

Test strip control solution usually comes in 3 ranges. I use the middle range because...well...that's usually where my values lie.

For instance: My current test strip container reads; #2 103-139mg/dL. That means than when this test strip batch was tested...the #2 range was 121mg/dL. 121mg/dL minus 15% equals 102.85mg/dL. 121mg/dL plus 15% equals 139.15mg/dL There's your error range!

So...I put a drop of control solution on a mirror, use a test strip...I get 120mg/dL. I do that again...I get 119mg/dL. Close enough.

Now...if I got 126mg/dL a couple times then what I would do is subtract 5mg/dL from any blood test because that's what those strips are off by...for that test strip container.

Trust me...if the "control solution" was useless - they wouldn't spend an extra penny on manufacturing it.


And, yes, the control solution is brand specific.

I'm a T2 diet controlled. With LCHF way of eating, my BG ranges well below any level that would be dangerous, and never goes too low, either. As long as my meter and strips seem to be testing consistently, I'm happy.

Now, if I were taking insulin, that would make a whole lot of difference and accuracy would be much more important. If I were prone to hypos, doing what bounty describes would be prudent.

In technical writing, always spell out what you are about to abbreviate. Example: low-carb, high-fat diet (LCHF). I had to look up what you meant. I am drug free too now for over seven years. I am Primal, which is another form of your LCHF. I usually don't like to mention it on this forum as it causes fights with those that won't kick the carbohydrate additions.

Right now I need to know EXACTLY what my blood sugar is.

Well that answers that question. I will see it Arkray has a solution for the premier.

Is there a way to "run a calibration" graph on my meter? If I had a base line, I could say what my test solutions actually were.

Not here. Go right ahead and discuss your way of eating.

I haven't posed here in several months. Maybe the culture has changed.

Primal is both eating and lifestyle. I "try" to do the lifestyle, but have limiting factors in my life that keep me from a lot of it. If anyone is interested, here is the link:

https://www.marksdailyapple.com/defi...mal-blueprint/

For food, I use the primal food pyramid:

https://www.marksdailyapple.com/intr...-food-pyramid/

My daily budgets are:

15 grams carbs per meal, no borrowing from other meals
60 grams carbs max per day
15 Max Glycemic Load per day.

It is EXTREMELY IMPORTANT that anyone trying to live drug free learn and live by Glycemic Load, not just carbs. If you exceed your load, even if within your carb budget, your blood sugar will be high and take a long time to dribble down, whilst etching your nerves and circulator system. You can get both carbs and Load over at:

https://nutritiondata.self.com/

You just add your load numbers up for the day.

There are supplements and Traditional Chinese Medicine (TCM) that helps too. I will leave that alone unless someone asks.

Also, keep in mind if you are doing the drugs and carbs thing, that by definition Allopathic Drugs (Allopaths are what we call Doctors in the west) are controlled dosages of poisons meant to cause a beneficial effect. But they are sill poisons and your body knows it, which is why you have side effects and rebound effects. Drugs are not medicine. They should only be used as an intervention, but not long term. (They have saved my life three times that I can count, so they have their place.)

Medicine has side benefits. For medicine, you have to find a full Oriental Doctor of Medicine (OMD) (8 year allopathic degree and seven years of herbal pharmacology, not an acupuncturist with a master degree in the Healing Arts) or a Naturopath.

If you doing drugs and carbs, it will catch up to you. You are being poisoned. So, make sure you get a good lawyer and get your will and trusts in order.

Now if I can only figure out what my stinking blood sugar actually is!!

Oh, just got the word that the Arkray test solution is 83-103mg/dL. WORTHLESS !!!!

So, how is this way of eating working for you?

I'm wondering how often you are testing since what you've mentioned is only once in the morning.
