Also; she survived in space slightly longer than any human ever could, even holding on to something while things were flying at her. GLaDOS said she was adopted. Maybe an abandoned Aperture Robot. Or maybe a Black Mesa Robot sent to kill GLaDOS. She can also get shot by many turret bullets and not die. Granted the turret bullets are just shoved in the body of the turret, and they don't have gunpowder in them, maybe this isn't such a feat. Her hair and nails didn't grow throughout the time she was in suspension. She is able to hold an ASHPD steady for hours on end
Reasons she may not be an android: In Portal (1), Chell bleeds when she is shot by turrets She probably wouldn't have to be kept in suspension (if she is an android, Ratman just killed test subjects for no reason)
