Which forensic tests increase the accuracy and reliability of evidence?

The forensic test that I think increases the accuracy and reliability of evidence is the analysis of DNA. This testing uses rigorous scientific experimentation and validation. To use DNA an investigator takes a sample of DNA such as dried blood or semen from the scene

DNA

the best type to use would be blood, semen, or saliva

Explanation:

DNA is the best proven test to get the most accurate results as opposed to fingerprints because while we say that no 2 fingerprints are alike that statement has never been fully proven while we may not have found any that are alike yet it is not a true fact that no fingerprint may match another
