On the test strip container label, you will find a range of color, each
corresponding to a glucose concentration.
1. Match the color in the circular window to the nearest color on the chart.
2. Compare the value from the chart to the value you obtained from the
meter.
This should be done between 30 - 60 seconds after applying blood to the test
strip.
If the two values approximately agree then the result is confirmed. If they do not
agree then repeat the test.
