Frequently Asked Questions About DNA Testing, Paternity and Genetic Identity


What is a DNA paternity test?
Comparison of the genetic code of a man and a child to determine if the man can be excluded from being the biological father of a child.
What is a DNA maternity test?
Comparison of the genetic code of a woman and a child to determine if the woman can be excluded from being the biological mother of a child.
Can a paternity or maternity test prove with 100% certainty that an individual is NOT the biological parent of a child?
Yes, if a child and another tested individual do not share the necessary genetic code, that individual cannot be the biological parent of a child. When this is the case, it is said that the person is excluded as the biological parent of the child.
What if a person is not excluded after a paternity or maternity test?
In the case of a non-exclusion a probability of paternity or maternity is calculated using the genetic information from the test. The strength of the DNA test results in a probability of greater than 99% that the person is the mother or father of the child.
Can a DNA paternity test prove with 100% certainty that a man or woman is the biological parent of a child?
No, there is no test that can prove parentage with 100% certainty. To accomplish this level of certainty every gene in the DNA of the child and parent would have to be compared. There are over 30,000 genes in human DNA so this is not a practical task. However, using simple but well-established statistical probabilities, today's DNA test provides the highest level of certainty available.
What if there is more than one possible father in a paternity dispute?

If the possible fathers are related, brothers or father and son, then they should each be tested at the same time. Related individuals share more of their genetic code than unrelated individuals. When resolving paternity among related possible fathers, testing may be necessary beyond the routine level. When there are related possible fathers, not testing all parties could result in falsely implicating a man.

If the possible fathers are not related they can be tested one at a time and they may not all need testing. If a man is not excluded after testing, it is highly likely that he is the biological father and it is probably not necessary to test additional unrelated men.

Does a child have to be a certain age before performing a DNA test?
No, as soon as a swab can be taken of the inside of the cheek testing can be conducted. A child can be tested as soon as after birth as the parent or parents wish. DNA Security, Inc. will NOT conduct testing on unborn children or aborted fetuses.
What is sib-ship testing?
Comparison of the genetic code of two individuals to determine the likelihood that they are brothers, sisters, or brother and sister.
Are the specimens submitted for genetic testing used for any other medical or clinical test?
No, only the test requested is preformed.
How long does it take to obtain DNA test results?
You should receive results from the laboratory test in approximately 2 weeks after the kit is received by DNA Security, Inc.
Are the genetic test results issued by DNA Security, Inc. confidential?
Absolutely. The results are strictly confidential and are only released to the individual indicated on the client ID and test request form.
Can the results for specimens collected in my home be used for legal proceedings?
Probably not. The tests are preformed in a nationally respected laboratory and the results are both accurate and reliable. The lack of a proper chain of custody; however, makes it unlikely the results you obtain would be admissible in a court of law. Please refer to the Legal Issues section for a detailed explanation of the chain of custody and legal admissibility.
How can I obtain a legally binding genetic test?
To obtain a test result that will be admissible in a legal court you will need to correctly and carefully complete the chain of custody documentation included with the EASY ANSWERS kit. This will requires that you arrange for a third, disinterested party to witness and supervise the specimen collection, packaging, and mailing. Refer to the Legal Issues section for a detailed explanation of chain of custody documentation and legal admissibility of test results.
