Testing blood glucose
5.3 Checking the test result using the test strip control window
The test strip itself allows you to estimate the test
result and thus also to check the displayed result.
Before the test
There is a round coloured control window on the
back of the test strip.
1 Compare the colour of this window with the
coloured dots on the label of the test strip
container.
The colour of the control window must match the
colour of the top coloured dot (0 mg/dL, 0 mmol/L).
If the control window is a different colour, you must
no longer use the test strip.
