40 | July - August 2017 | t 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 posi- tives as well as false negatives. Several samples were taken to ensure the test was performed accurately and the results could be verified. Our son was born happy and healthy, but the memories of all the testing and the quest for accuracy with the results stayed with me.

The methodology was very pedestrian. If the results were labeled as green, nothing was done. If the results were marked as yellow, another sample would be taken in the coming weeks. If the sample was flagged as red, the oil and filters were changed. There was no in-depth analysis, and whatever data was presented on the lab reports was treated as absolute truth.
