You now have about 5 minutes in which to draw up control solution with
the test strip.
Take the bottle of control solution.
Open it and wipe the tip of the dropper with a clean, dry paper towel
in order to remove any dried-on residues.
Invert the vial and hold it downwards at an angle. Squeeze it gently
until a small drop is suspended from the tip.
Apply the drop to the surface of a clean, easily washable object
made of glass, porcelain or stainless steel (e.g. a plate or spoon).
