Post-Mortem Viability Test

It is possible to perform DNA testing on deceased individuals using their stored samples. The post-mortem viability test is performed on a sample from a deceased individual to determine if the sample yields sufficient viable DNA to proceed with further testing. The fee for the viability test is separate from the relationship-test fee, and varies according to the sample type, as specified in the Unusual Samples List.



Turnaround Time

  • Five (5) business days from receipt of samples


Chain-of-Custody Requirements

  • Post-mortem samples submitted for DNA testing must fulfill the following requirements:

  • Deceased samples are collected by a neutral third party, such as a coroner’s office, funeral home, or medical examiner

  • The deceased individual’s next of kin completes and signs a Deceased Patient Custodian Consent Form (COC-4004) to authorize testing; this is submitted together with a copy of the next of kin’s ID

  • Next-of-kin relationship must be verified at the time of signing consent

  • The collector of the laboratory storing the deceased sample signs the Postmortem Specimen Identification Form (COC-4005).

Upon confirmation of viable DNA samples, chain of custody requirements for the subsequent DNA test (e.g., paternity test) to be conducted must be used.

  • Samples are collected by a neutral third party, such as a clinic or laboratory

  • The individuals tested are positively identified (i.e., they present a government-issued ID to be photocopied and/or they are photographed)

  • A standard kit is used

  • Each party completes and signs a Client Identification and Consent Form (COC-4002-CA)

  • The kit may not be in the possession of the clients prior to or after being collected

Non-Chain of Custody Requirements

  • Post-mortem testing for non-chain-of-custody purposes is not performed by TADNA

Information to be Obtained from Clients

  • Type and quantity of available samples

  • Storage method of available samples (e.g., frozen, refrigerated, or room temperature)

  • Type of container the samples have been stored in (e.g. purple-top EDTA tube)

  • The date and cause of death

  • Confirmation that the facility in possession of the stored samples is willing to release the samples; (many medical examiners and hospitals require either a court order or written permission from the next of kin before releasing a sample)
