The DNA testing performed is not affected by the DNA of bacteria, common foods, tobacco, or toothpaste, etc. Q: How does a buccal swab sample differ from a blood sample? A: For purposes of identity testing, there is no difference in DNA derived from buccal swabs or blood. Q: Is the re-collection rate higher with buccal swabs? A: Peace of Mind Genetics has not experienced a higher re-collection rate for buccal swab specimens. In Peace of Mind Genetics' experience the re-collection rate appears lower than re-collections for traditional blood testing. Q: What are the procedures to prevent a mismatch of samples? A: Buccal swab collection is performed using different colored swabs for the mother, child and alleged father to minimize specimen mishandling. Q: How many test systems (loci) should be run? A: The multiple genetic systems selected for routine testing by laboratory designated by Peace of Mind Genetics, exclude on average 99.99% of falsely named men from paternity. Q: Are ...  more

The DNA testing performed is not affected by the DNA of bacteria, common foods, tobacco, or toothpaste, etc. Q: What are the procedures to prevent a mismatch of samples? A: Good laboratory practices that incorporate exclusion confirmation and duplicate testing if independent specimen preparations help prevent and detect mismatched specimens. Buccal swab collection is performed using different colored swabs for the mother, child and alleged father to minimize specimen mishandling. Q: How many test systems (loci) should be ran A: The multiple genetic system selected for routine testing at Lab Test Unlimited exclude on average 99.99% of falsely accused men from paternity. Q: Are any other tests, such as AIDS conducted at the time the genetic testing is performed? A: No other test are performed. Q: Why can't a simple genetic test, conducted in a physician's office, be used to determine paternity? A: Genetic analysis is more complex than most physician office laboratories are Capable of ...  more
