When the paternity of a child is in question but the child's alleged father is deceased, DDC UK may be able to perform a paternity test using a preserved biological sample from the deceased. Before a paternity test can take place, however, the deceased's biological sample must be tested to verify that it contains sufficient DNA for genetic testing. This preliminary test is known as a viability test.
A viability test can be performed on any preserved biological sample from the deceased, such as blood, hair, or other body tissue. But first, the appropriate consent must be obtained in accordance with the Human Tissue Act and other government regulations. Usually, the deceased person's next of kin, if an adult, can provide consent (please call us for more information).
Once the appropriate consent is acquired, a viability test can be performed. If the viability test confirms that the preserved biological sample does contain sufficient DNA for further genetic testing, DDC UK can use it as the alleged father's sample in a paternity test. (The samples for the child and the child's mother are obtained via standard buccal swab collection.)
The fee for DNA viability testing varies depending on the type and condition of the preserved sample. Further, it is separate from the paternity testing fee that will be applied if a paternity test is ordered.
