Hi. It's so easy, it's like falling outta bed! Hands should be clean, but unless you have a dirty job, no one washes just for testing if your hands are reasonably clean.
Don't dip your fingers in honey
over the test site; glucose
on the skin would, of course, influence results. Otherwise, no special routine. No one uses alcohol
pads (like they do at doctors offices, etc). It's SO easy! Good luck!
