Contour vs ContourXT

[DavideB]

I have done a reading,

Contour 6.6
ContourXT 7.6

Any Reason?

Thanks

PS Just done a Test with that pink stuff and the XT was 18.8 and the contour was 7.6 Now this means the XT was high...What do I do now..

the XT was the new reader that just arrived with that free offer

My contour reads lower than all my other meters, (i have a contour, contourXT, freestyle insulinX and a onetouch verioIQ)
Not sure which one is accurate but when i hypo, my contour agrees with that! But once i went hypo and my onetouch verioIQ read i was 5.9mmol, when clearly i wasn't. So i tend to touch my contour (the basic one, not the XT)
