In certain cases, elimination samples may be requested for DNA analysis. Elimination samples are used to help determine the value of a specific biological sample.

For instance, if a cigarette butt is recovered from a crime scene, elimination samples could be obtained from individuals who had access to the scene. This may show that the cigarette butt was left by the perpetrator.
