5. Prepare and apply control solution
Shake the control solution vial before each test. Remove the cap and
squeeze the vial to discard the first drop. Then wipe the tip with a clean
tissue or cloth. Hold the vial upside down and gently squeeze out a
hanging drop.
Touch and hold the hanging drop of control solution to the narrow
channel in the top edge of the test strip. Make sure the confirmation
window fills completely. Control solution should not be applied to
the flat face of the test strip.
