Genetic testing involves sequencing the DNA of one person and then analyzing every strand out and testing each part for specific diseases and disorders. In any case this information would be regarded into the Doctor patient confidentiality policy. People now are concerned with how readily available this information would be to others, and should testing be recommended for all patients.  Another problem parents and children have is if testing should be done as a child or done as an adult, due in fact to the privacy you would have as an adult but the more aware you would be a child and then make more cautious decisions. Yet for every positive there seems to be another negative effect lurking around the corner such as, false positives and false negatives which could major distress and possibility of passing a faulty genetic trait. Along with the simple results being good or bad there could be physiological distress on the patient and anxiety as well. On top of results to your children and yourself, there could also be reasoning to fire you or not insure you because you inherited a disease from your parents.
