Genetic Identification

When a DNA testing laboratory carried out a DNA test they encourage the individual to deposit their DNA results into DNA banking. This is also known as DNA safeguarding which essentially allows access to that person's genetic information for use in future situations. Using genetic identification a DNA testing laboratory can identify an individual based on the sample they gave in the past.
There are many situations that might warrant genetic identification, such as a person going missing, an unidentifiable body being found and a DNA test being carried out on the deceased. Had they not deposited their genetic information into DNA banking at an earlier time they may remain unidentified, but having that information stored gives forensic experts a direct and reliable reference to use in solving a case. Other situations include testing children of a deceased parent for diseases that they may inherit, or holding DNA of people who work in particularly risky jobs such as soldiers or those in the police force.
Genetic Identification doesn't necessarily need to rely on DNA banking to be successful. Comparative DNA tests can also be carried out on close relatives of the person who is in question, to see whether they are indeed the person they're suspected to be. Laboratory professionals simply use the same processes used in paternity testing and all other genetic tests such as RFLP and PCR. Once a dye has been added to the results so they can be read by a member of staff they can then be compared to produce conclusive results.
