Lifescan blood glucose monitoring system manual

There is a difference in the glucose levels of venous blood (usually drawn from a vein in your arm) and capillary blood (blood from a fingerstick). After a meal, the glucose levels in the capillaries may be 1.1–3.9 mmol/L higher than the levels in venous blood.6 If your lab test is taken while you are in the fasting state (before breakfast),

this difference will be minimal (0.1–0.3 mmol/L).7

Variation may also occur between your Meter and the lab if the two tests were not done within 10–15 minutes of each other. Blood glucose values

change rapidly, especially after you have eaten, and the two tests could have very different results.8,9
