Not sure what to do

Just got new contour next meter. Opened it up and paired with my phone, took bg reading and went right to phone. Took my old meter (accu-check aviva) took reading to compare. New meter 247 old meter 194 did solution test on both, new good, old failed, but only high by 4. I would think if the old one was reading low it would read low on control solution or am I wrong. Monday will get test from lab to check. Thinking on using new. Thing is if I use new and it’s reading high then I could go to low, you see where I am going with this. I am mdi with crazy spikes. Do corrections, manual dual bolo session a lot during day so I guess I just have to pick one.

Trust the Next. Trust the Next. Trust the Next. Trust me, the control solution results aren’t going to be definitive for such a situation. Most companies make several control solutions (for various parts of the range) and hardly anyone has them all in their possession. Trust the Next.

Yes I am, is kind of disconcerting to think my readings were low, have been working hard to get averages down, was down to 204 bg average this week. Which is improvement. Was around 250 beginning in December. Anyway thanks.

Next time your Endo has you do blood work take your meter and take a reading and compare it with test results


I would have tested again to see what the results would have been. The same or more in line with each other.


I live 2 blocks and have to go get INR for warfarin for heart. They are as hard to control as blood sugar. Am going to have doc put in for lab to get real reading to compare to mine at same time.

Left a lot out, live 2 blocks from hospital and have weekly ONE’S done.

Inr’s not ones.

Contour next is very accurate for me. Wouldn’t use another meter now and have been testing for 50 years or whenever testing started.

50 years might be a bit of a stretch. LOL!

It is a bit of an exaggeration. 50 years ago I was testing urine not blood by dropping a Clinitest tablet in a test tube to see if it turned blue or orange. Couldn’t test your blood 50 years ago and somehow we survived without all the technology available today.

Me too. Especially when using as input to dexcom.

The higher the BG, the more variation I see in multiple tests from SAME drop of blood, on the SAME meter. Sometimes I will do a third test, so I don’t calibrate with bad data.

I was diagnosed in 1981 and used urine testing until 1982/83 when I started the Ames Glucometer. I so wish I would of kept the old “brick” for nostalgia.:grin:

My first tests were done with Tes-Tapes (1978-'79 or '80). Peed on a narrow paper strip. Yellow; OK, green: spilling urine with no clue what actual bg was. Not only that but I could be hypo and urine might still show glucose at the time.

Amazing how we all survived with the technology (or lack thereof) back then.

I’m mostly trying to figure out how I didn’t die in my sleep when on Regular and Lente, with no meter, no clue about carb counting. It’s a miracle I’m alive–no exaggeration.

It’s amazing how quickly diabetes technology emerged back in the '80s, even though the tech-tempo seemed glacial at the time. I was diagnosed in 1984 and started right out using BG Chemstrips, a fingerprick blood test that turned the reagent of the test strips a degree of color that was then compared to a standard panel printed on the side of the test strip tube. The test required leaving the blood on the strip for a certain amount of time, wiping the blood off at a certain time, and then reading it at the prescribed time. Get distracted during this timing sequence and your results were compromised.

You could readily conclude, for example, that your blood sugar was somewhere between 80 and 120 mg/dL (4.4-6.7). It’s not nearly as precise as today’s meter-tech but it was much better than the urine testing methods people diagnosed in the years before me used.

I am so amazed and so thankful of my parents. I don’t know how they did it without losing their sanity. The wild swings the insulin peaking, the “exchange diet” that was not anything we would use now. And the one shot a day, calling the doctor each morning with urine test results (test tube, eye dropper and tablets) and changing the dose. No way to know if I was swinging low in the middle of night except one of them getting up every night in the middle of the night to check my forehead to see if I was sweating. It is so amazing they made it and all their help and support made me the strong, caring, compassionate and disciplined person I am. Thanks Mom and Dad! Love you and miss you everyday!


I know it is very irritating but those reading are within the 20% error margin allowed and even the newer 15% allowed. If the 247 had an error margin of -15% you would have 210. If the 194 had an error margin of +15% you would have 223. The 247 having an error margin of -20% would be 227 and the 194 having an error margin of +20% would be 232. If looked at that way, they would not be that far off from each other and they are allowed to have that much of a difference and still be considered to be accurate.
As frustrating as it is, the fact is, you can do two readings, one right after the other, on the same meter and get results that vary that much and both would be considered to be accurate.

I would have done that too Jim. Sometimes, using the same meter, I get two reading back to back that are quite a bit different, and this is at much lower levels, like around 70. When that happens I do another reading to see which one to disregard. Most of the time the third reading will be really close to one of the readings, so I know to regard the one that is far off as just a fluke. It really isn’t a rare occurrence.
