It has been a couple years now since the birth of my first child. I remember going to the doctor’s appointments with my wife where countless exams and tests were conducted to confirm that the pregnancy was progressing as it should. There were measurements, readings and occasionally blood tests. One of the blood tests was designed to look for genetic abnormalities. The literature on this test explained there was a chance for false positives as well as false negatives. Several samples were taken to ensure the test was performed accurately and the results could be verified.
