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)
