씰 Remove a test strip from its container. Close the container
immediately. The cap contains a drying agent which ceases to
function if the container is left open, rendering the test strips
unusable.
씰 Check the round control window on the back of the test strip
against the colour scale printed on the test strip container.
The colour of the control window must match that of the
colour interval at the top (0 mmol/L).
If the test strip shows a different colour, do not use it.
