The overall process where private organizations in the US collect DNA of deceased people is relatively simple. Funeral homes began offering the service in the late 1990s and the practice continues today. Before embalming a deceased individual, the blood of a person is collected and placed onto specially coated cards. This card is then stored at a vault of a private DNA library. The process can still be completed after a person is embalmed if the family changes its mind. The funeral home simply takes a sample of skin tissue and preserves it in the facility. This allows the family to maintain a long-term genetic fingerprint of loved ones.
Some companies even offer home DNA sample kits to preserve the genetic coding of individuals. Hair, blood and cheek swab samples can be used for long-term storage. Since the popularity of this has led to a number of damaged samples and questionable actions by companies, the City of San Bruno in California offers instructions online for the proper storage of DNA in the freezer.
