Some questions;
How many tests does it hold?
What's the highest it can test, and what's the lowest.
How correct is the testing / accurate?
Hi Raymond,
Not exactly sure what all your questions exactly were intended to get answers on, so please allow me to alloborate a bit where I think its relevant, as to provide you as broad and complete answers to your interest in the Aviva Expert:
First off and to disclose, I have been a huge fan of Roche Diagnostics all my many years as a Diabetic, so that may color my answering you, but I will try my best to stay very objective and fact based throughout. Roche did also miss the train on the CGM technology, so I went with the FreeStyle Libre some years back.
But now back to your good questions
RJ: How many tests does it hold?
In terms of test strips, it unfortunately use the old fashioned model, where you have to fiddle with a seperate container with your test strips and then insert a new one for every test you want to take. So its not as easy as the Accu-Check Compact Plus which has a drum pre-loaded with 17 test strips inside.
If your question was more about the memory bank within the Aviva Expert, then it can store the results from your last 1000 tests. Battery wise, it can typically support 1800-2000 tests before you need to change them. Great thing about the batteries is also they are of the easy obtainable AAA type! So not the sometimes hard-to-find little lithium button batteries-type that also have a much shorter lifetime.
RJ: What's the highest it can test, and what's the lowest.
RJ: How correct is the testing / accurate?
Important to understand before I answer these questions is that those technical specs actually are determined by the test strip itself and not by the meter as such. So other Roche meters using same test strips will also have the same technical aspects. So lets see what these values are for the test strips used in the Aviva Expert, which is the ACCU-CHEK Aviva Plus test strips!
Just figuring out that Roche appear to have taken all deep tech info off the internet, probably due to competition and also regulatory compliance exposure, as they now persistently refer to the leaflet that you find inside your product box with the test strips for detailed specs on the ranges measured and their accuracy. Also because these no doubt are influenced by local regulations all depending on in which country you purchase them in. For me locally the bg is measured in mg/dL.
Here the specs details that the lowest result that can come out (without the meters interprets just as 'LO') is 20 mg/dL. So that is approximately the same as 1.1 mmol/L. Max measure coming out before saying 'HI' is 600 mg/dL, so approximately the same as 33 mmol/L. I was unfurtunately not able to find exact and varified numbers for its accuracy over a normal distributed sample size. It would be interesting to find out of this information now also is present just on the leaflet inside the box when you buy the strips.
Best of luck with it!
