In what scenario is DNA testing primarily utilized for identification?

DNA testing is utilized primarily in scenarios where no other documentation is available. This is due to its nature as a highly specific method for identifying individuals based on their genetic material. In cases where other identification methods, such as fingerprints or personal identification documents, are lacking or inconclusive, DNA serves as a reliable alternative for confirmation of identity.

The reliance on DNA in the absence of other evidence highlights its significance, especially in forensic investigations where establishing the identity of deceased individuals is crucial. DNA can provide definitive results that link an individual to a crime scene or confirm identity when other methods are unavailable. While DNA testing can be costly and time-consuming, its application is vital in resolving cases where traditional identification methods fall short. This makes its use less about being a last resort due to financial considerations and more about being an essential tool when necessary information is missing.
