They would know if there was an genetic deficiency with Alianah from the moment they were in the hospital as newborns.
I think genetic testing is one of the standard blood tests that are issued in the hospital, and she would know about any issues within 2 weeks of birth.
Did everyone here have their child geneticly testing at the birth of their child? We did. As I understand genetic testing started back in 2003 or something like that.
