How can anyone really believe that an ultrasound (or any other piece
of equipment) can tell the day of conception/due date/ age of baby
to the day?? Who are we kidding? What are the error bars??? The more
people ask that question, the more technicians and docs will remember
that the error bars exist and must be considered in making
diagnoses and RECOMMENDATIONS (not orders, recommendations) Mothers
deliver babies, not doctors or midwives.
