How far should screening go?

I was alarmed to hear she'll be getting fingerprinted at the sheriff's office as part of the screening process. Instantly I conjure up scenes of frame-ups and corporate scandals. I want to know, should this raise a flag? Would you submit to fingerprinting, blood tests and who knows what else (genetic code screening etc), for a programming position?
