Postmortem DNA Test

Who needs a postmortem DNA test?

A postmortem DNA test should be ordered if a close relative has recently passed away, and you need to establish the legal relationship of that person to a child, sibling, or another family member. Often, people need proof of a relationship to handle various matters related to the estate of the deceased or to access government benefits like social security.

How do I schedule a test?

Health Street works with you, the coroner’s office, or the funeral home to obtain the specimen from the deceased. The other person being tested will need be scheduled for a cheek swab at one of our clinics.

When will I get my results?

Generally, it takes about a two weeks to obtain the results of a postmortem DNA test after all specimens have been collected. The signed lab report is emailed to you, and an official hard copy is sent later via US mail, which may take an extra week or two to arrive.

Who determines the results of my test?

After our lab extracts the DNA from the deceased, and the other party has gone in for a cheek swab, our geneticists study 21 genetic markers for each person. They perform a statistical analysis to determine the likelihood that the parties are related.


NY residents must provide doctor’s prescription for all DNA tests, and must pay $45/person lab fee directly to lab.
