Newborn Screening yields 90% false postives (WSJ)

New born genetic screening, now required in all 50 states, has a false positive rate up to 90% For each case of an infant genetic disorder identified early and treated, nine other parents are scared out of their wits when the doctor says "There is something wrong with your baby's blood". Speaking as a practicing parent , I can tell you that the fear of a congenital defect in your child is the worst of parent's nightmares. The nine months of pregnancy are plenty of time for fear of congenital defects to grow in both father and mother.
Each false positive screening result will trigger a frantic round of test and retest, treatment, doctor's visits, special diets, special this and that. A newborn child is the most precious thing parents possess and they will do anything to preserve its life. Cost is no object when a newborn's life and health are at stake. The fear, sorrow , and uncertainty put the parents thru a psychological hell.
Yet another advance in medical technology puts nine parents thru hell for each newborn actually aided. And we wonder why 14% of GNP goes into health care. A test with a 90% false positive rate is not the responsible practice of medicine.
