YEP -there was indeed an MHRA alert out on tuesday 10th june 2014.
There are "Enhanced instructions for proper testing with the Accu-Chek® Mobile system to avoid the potential of falsely elevated blood glucose readings".
Readings were shown to be inaccurate and could read higher than actually reality .
Yes, it seems a small number of people have reported elevated readings, thought to be caused by incorrect testing methods such as dirty hands, smearing blood, not applying the blood drop quickly enough etc rather than the meter itself being faulty.
I recently had an ACCU check mobile unit free from the manufacturer - having always used a glucomen Lx plus which the hospital gave me. When I first tried (as per 'new' instructions) and did a reading on my old reader at same time, there was a significant difference in the reading. Have just done same thing again and got 5.8 on accucheck and 4.5 on my old meter. Also seems to only do blood reading, not ketone's (maybe I've read this incorrectly?). Is this normal or where can I get test solution? Thanks
Really glad I found this, I've just purchased a code free blood glucose monitor (a couple of days ago) and borrowed my dads accu-chek monitor, tested same drop of blood on both monitors this morning at the same time and if memory serves me right (should have written it down) accu-clerk gave me 8.7 and code free 7.9
For type 2's it isn't that important as all we are doing is looking for trends and seeing what certain foods do to us. As long as we stick to one meter and don't keep using 2 different ones, there isn't a real problem. However, with type 1's or type 2's on certain meds it is very important.
I found that my accuchek mobile read 13.5 just now and my contour next usb read 12.2 with the same sample of blood, although I am type 2 my numbers are given to nurse to increase my insulin.
Like @ck18 and @Kaz70 those results are within the normal expected variation between two tests or two meters, so don't worry, it doesn't mean anything.
