Accuracy of the Reader's built-in meter
Results from the Reader's built-in meter may vary slightly from your
actual blood glucose value. This may be due to slight dierences in
technique and natural variation in test technology. The table below
shows the results of a study where 119 typical users used the built-in
meter to check their blood glucose level. For example, in the study, the
built-in meter gave results within 15% of true blood glucose level 115
out of 119 times.
