Which of the following best explains the role of a genetic counselor

If I were hired as a genetic counselor to advise a couple about the odds of the couple having a baby with a genetic disorder and I wanted to order lab tests to be done on the pregnant mother to determine if the baby has a genetic disorder (amniocentesis) - what kind of test would be done? How would the test determine if the baby has a genetic disorder or not? If it is determined that the couple's baby has a genetic disorder, then what advice should I provide to that couple? Why? What if the couple went against my advice? Whose advice (mine-the genetic counselor representing science or the couple representing society) should be considered?
