DNA paternity test is definitely the biggest discovery of the medical community in 21st century. So far, DNA paternity test is the most effective way to distinguish people. For judges, there is nothing more convincing such as handwriting, fingerprint or witness than it. During the investigation, apart from the DNA extracted from the blood collected on the spot by policemen, it also can be found in hair, gum that has been chewed, cigarette ends and other samples which may not be obvious.
DNA Paternity Test not only helps policemen bring criminals to justice, but also right the wrong. The founder of DNA paternity test may never expect that his accidental discovery would become one of the most important proofs in today's judicial circle. Despite its great advantages, DNA paternity test must be preserved carefully. Once contaminated, it would lose its value.
