accuchek aviva 3 vs. micro relion
Per an MD's recommendation, I bought the Aviva and its expensive strips, and decided to see how accurate it was. So on same finger - same blood sample these are the results while on Metformin er
Aviva Micro Relion
4pm 107 133 (!) (haven't eaten since 12 noon - 21 gm carbs)
4:01 119 112
ran out of blood - so same finger, new puncture:
4:04 115 122
so since I didn't wipe off the first reading (i guess it was too serous) the first reading was 107 with the Aviva, but same sample, more blood - it was 133 on the Relion. The MD had been saying that the Relion was not accurate in that it was too low. Hmmm.
So, the Aviva had a 12 point difference, and the Micro relion had a 21 point spread. wow.
Did other people get the same results?

Tigger, you tested at the time - and center of the field - where they should be most accurate. Which lets us know we're all treating ourselves based on a cloud of fluff. Which means they ought to give us more strips in those thar cans so we can do more testing.

Hey Leo2 - thanks for replying - I certianly wish the Aviva was as cheap as the relion micro. Well, I was told to get the AVIVA for its accuracy - and - well - the values were actuallylower than the Relion. I will use up the relion, because it uses only like .3 ml or micros fo blood vs. the 0.6 of the Aviva. Needed more blood for the Aviva. What meter do you use?

I had a one touch ultra mini and now have the accucheck compact plus. The accucheck always runs higher than the one touch but I have no idea which one, if either, is correct.

Me too - but the other comments below really clarify precision vs. accuracy. Thanks for your comment - nice pciture - you almost look like a Gainsborough protrait holding your pet like that.

yikes - thanks for the info - ugh, later on like maybe 4 hours from the last meal - still drinking my coconut milk with coffee - I will redo the test - on seprate fingers - and will report back later. Thank you for the info.

Ok so then, I ate at 1130 am, 12 carbs 10 grain cooked rice + KFC grilled chicken drumstick and thigh, sugar free jello,
It is 5:46 pm and these are the results of my BS on 2 different fingers within seconds of each other:
Aviva =99 Micro-relion = 97.. Very close to each other. This means that they are both fairly reliable? Sigh - well, I way prefer the lesser amount of blood that the relion requires - I guess I'll just see which I like better later.

You are not measuring accuracy you are measuring precision. Accuracy is only available when you compare your meters to the lab machine. Visualized an archery target. Precision is how close the arrows are clustered. accuracy is how far the average arrow position is from the bulls eye.

PS I never found the Aviva to be very accurate they read high compared to the lab test. Most new 5 second meters have very poor accuracy. I really miss my 60 second meter from 10 years ago it always read 5 % below the lab test.

When you say "lab test" are you referring to the HGA1c, or do you mean you take the aviva with you during the lab sampling, and test it on the spot? The last time i did that, I flustered the phlebotomist so much, I had to come in for another sampling - perhaps the sample hemolyzed - who knows, I just had to go in for another blood draw. Icch.

No the a1c but a blood sample from a vein that is cetrifuged and the sugar concertartion meased with a lab grade device. The meter measures for 5 second the maximun current that is proportional to BG. In the us the plasma meter calibration is supposed to match the lab test. It did ten years ago perfectly. The meters measure the average reation betwem the test strip and the blood over aperiod of 60 seconds making it much mure accurate.

Anthony - wonder if they make any 60 second meters now? It would be great if we can that kindof accuracy. I am happy to sacrifice seconds for accuracy.

I fully agree I would gladly wait longer and would measure more often. Now my BG is such that what I get out of a measurement is mostly random noise.
