Error: Internal Quality
Control Failure
The test strip failed the
internal quality control
check. The test strip is
unusable.
Solution:
Turn the meter off and
remove the test strip.
Repeat the test using a
new test strip and blood
taken from a new
fingerstick from a
different finger.
Notice
After removing a test strip from its container, always
make sure to immediately close the container
again with the stopper. Exposure to external
influences (e.g. humidity or ambient light) may
deteriorate the test strips. The blue reagent line on the
back of the strip may turn pink or purple if the strips
have been exposed to external influences.
