Did you or your children have a Guthrie (heel prick) Test when you/they were born. If so your dna is already in somebody elses control. The company that does the testing owns the results and therefore can do what they like with them. And big mister government official can supena them any time he likes. And just to make things interesting the cards the blood is placed on are NEVER thrown away, incase somebody sues them for not diagnosing one of the target conditions.
