The laboratories surveyed were not commercial laboratories. There are no published studies of the private sector. Genetic testing of children is a complicated issue. With more tests available, and as costs become less prohibitive, pressures to test more children may grow. Unless there are direct medical benefits to the child in the near future, caution appears to be in order.
Children deserve the opportunity to make their own decisions about testing when they become adults.
