Readings may potentially be inaccurate:

• If you use substances other than fresh whole blood to test your blood glucose or β-ketone
• If the meter gets submerged in water
• If the meter is shocked due to static discharge
• If the meter is exposed to strong electromagnetic radiation
• Other brands of test strips are used in the meter
• Using expired glucose or ketone test strips
• Using the first drop of blood when testing your blood glucose/ketones
