Warning • Blood glucose values are displayed in mg/dL or mmol/L. You risk damaging your health if you measure your blood glucose value using a unit of measurement with which you are not familiar, misinterpret the values and consequently take incorrect measures.
  • Page 8 • A haematocrit value (proportion of red blood cells) between 30% and 55% has no significant influence on the measurement results. • A very high or low haematocrit value (proportion of red blood cells) may lead to incorrect measurements. In the event of a very high haematocrit value (above 55%), the displayed blood glucose value may be too low;...
