5%: The blood glucose meters should be accurate to withinh 5%. This means that a blood sugar of 100 could be reported by the meter as anywhere from 95 to 105. For the daily use this is quite accurate.

+/- 15%: Unfortunately, most meters are only able to tell you a value within about 15% of the "real" value.
