We cannot test someone who has not had sufficient sleep the night before, someone who is emotionally upset, someone who is ill or injured, someone who is in pain, someone who is distressed, someone who smells of alcohol, and a female who is pregnant. If a person is found to be unsuitable for testing, the polygraph session will be terminated and the appointment would have to be paid for in full."
