I had another prescreening call, for an MRI I have to get later this year. The calls are basically probing for anything that might be an issue in sticking a body into a tiny tube inside of a humongous magnet.

They asked about claustrophobic issues, implants, wires, screws, accidents that might leave metal inside, and so on. Apparently there is a series of gender-specific questions.
"Have you had a pregnancy test recently?" "Nope" (Smile)
"Are you pregnant?" "Um... No" (Still smiling)
"When was your last period?" "Uh... Never?" (Starting to giggle...)
"Do you use an IUD?" "Ah, nope." (Grinning ear to ear...)
OK, just a phone call, and obviously my new ID is in The System, but wow, what a funny validation!
I can't wait to see what happens when they code a prostate exam into my record. (Computer explodes...)
