DNA Testing - Frequently Asked Questions
How accurate are the DNA test results?
DNA paternity testing is very accurate, and will yield results that indicate either a probability of
paternity greater than 99% (inclusion) or 0% (exclusion). For siblingship and grand-parentage testing we
aim for a conclusive range of either >90% (inclusion) or <15% (exclusion). For more information see our DNA
Problem Solving Workbook.
What if the two alleged fathers are related?
It is best to test both alleged fathers, especially if they are related, so that one can be excluded. If
only one alleged father is available, then you must select the extended testing additional service. The
final report will have additional data and a likelihood ratio calculated.
Is blood more accurate than cheek cells when testing for paternity?
No. Cheek cells collected using the GeneSwabs yield results with the same accuracy as blood samples do. The
DNA is the same; regardless if it is collected from cheek cells or blood. Also see: ABO Blood Type
Paternity Calculator, which can be used to assist in determining possibilities of paternity based on ABO
blood typing.
How soon after submitting my specimens will I have results?
For paternity tests GeneTree will provide a detailed and comprehensive report 3-10 working days after
receiving your specimens. Other tests, such as a siblingship analysis, may take 4-6 weeks. For Express
Processing fees please call the processing office.
What if my alleged father is deceased, can paternity still be established?
Yes. Paternity can still be established by testing other known family members to reconstruct the DNA
lineage. Aunts, uncles, cousins, siblings and grandparents can all be used to reconstruct family
relationships. Please contact GeneTree for more specific information.
How old must the child be to have a paternity test performed?
There are no age limitations. The GeneSwab Specimen Collection kit can be used on infants. Expectant
mothers can learn about procedure and methods available for prenatal paternity testing by calling the
office.
For prenatal (before the child is born) DNA paternity testing questions please see the following pages for
more information:
Prenatal Paternity Testing Services and Conception Calculator. The conception calculator is used for
calculating the due date of an unborn child, the probable date of conception, the dates a pregnancy test
would be positive, the dates that a CVS test can be performed, the dates that an Early Amnio test can be
performed, and the dates that a standard Amnio Screen test can be performed.
