Couldn't agree more.
Quoted message said:The Ultra is one of the most popular machines in the UK; I see it as giving a more accurate
reading at all temperatures than the Accuchek Active. However, the Active is also a very big
seller (of course we don't have to worry about strip costs).
I have both machines. The Accuchek active is a good machine and uses a totally different test
strip that requires a greater amount of blood. It works differently and will give readings about
7% lower than your Ultra machine due to its method of working. I think that the "chromo" method
refers to the fact that it passes a light through the sample and measures the change in colour to
determine the glucose content. The Ultra works differently but is believed more accurate.
Certainly if you keep control using your Ultra then your control will be that little bit tighter.
Since I asked for help, I have done my own experimenting and measurements. I have used both machines
for a week, taking a reading on both machines at the same time from the same blood, switching who's
first and who's second every time. In all I had 26 measurements.
I computed a statistical correlation (spearman's R) of the resulting numbers, and it came out to be
.96. That is an extremely, extremely high correlation. A correlation of .96 means that there is no
difference between the reliability of these two machines.
The active did bring in numbers that, on the average, were 5.5% lower than the Ultra. However, when
in the past I have checked the Ultra against the lab's results and the Ultra tended to be a little
high. All in all, I think the Active is a little more reliable, perhaps by a gnat's hair.

I actually prefer the Active in general use, it is reliable and easy to get on with.
Also, the Active is made so it's easy to test from other sites, not just the fingertips. You can
take the strip out of the machine, get the blood on it from the alternative site, and put it back in
the machine. In that case the wait time doubles from the regular 5 seconds to 10 seconds.
Quoted message said:I notice it gets through batteries faster than the Ultra though...Luckily they are free
in the UK.
I wouldn't worry at all...just remember the reading is just a little bit lower than you would
normally expect.

I must convert.
Looking at the Accu-Chek offerings I saw their Active machine. It claims to measure in 5 to 10
seconds and use only 1 microliter blood. However, they say that they use "chromo" technique,
which is different from the OneTouch Ultra.
Is anyone here either using now or have used in the past the Active Accu-Chek strips? Are (were)
you happy with it? Was it reliable? Any other gotcha's I should know?
