Also, my medical screening is the day after the interview/sim, assuming I haven't washed out by then! Told to bring running shoes for the treadmill test, pair of contacts an the box they came in (with diopter markings), and spare glasses. A friend formerly of ANA advised not to exersize (run, lift, work out) for at least several days prior, so as not to introduce ketones or lactic acid into your system that would affect your blood screenings.
