Analysis of tissue/cells taken from deceased participants (father/child) can be used for paternity testing. However, a test to determine the integrity of the samples must first performed to check for the presence of DNA that can be used for the paternity test. Our laboratory needs to be first advised of the state of the sample including size, age and storage conditions. If a legal test is to be performed documentation will have to be provided by us to the doctor collecting the tissue sample.

Other unusual samples (other than buccal swabs) such as hair and cells from personal items can be used as a reference for a paternity analysis if the father is deceased or not available. Clients requesting this service will be required to sign an Unusual Sample Authorization Form which states that the client understands the limitations of these tests due to the nature of the DNA in these types of samples.

Deceased and unusual sample testing attracts a sample verification fee separate and apart from the paternity testing fee. The lab must be advised beforehand of the type of sample that is available before committing to carrying out these tests.
DNA from these tests may not be usable hence a paternity test cannot be carried out. Clients will be advised of the DNA verification results. The turnaround time for this sample verification is 7- 10 working days.
