Quality Control Test
IMPORTANT
If you fail to completely insert the test strip,
the test may start; however, you may receive an
out-of-range result.
IMPORTANT
You have up to 2 minutes to insert the test
strip after the control solution is applied. If
you insert the test strip after 2 minutes, you
may get an out-of-range result or an error
message. Discard the test strip and repeat the
test with a new test strip.
The QC test result appears in approximately
10
30 seconds. The time may vary depending on
the temperature and glucose level.
