[DNA-based personal identification in disaster].

The disaster is a sudden unexpected event that causes serious human injuries and deaths as well as missing persons. The main tasks of forensic DNA laboratories are to identify victim in the disaster. After reviewed the previous disasters and related studies, we proposed a new procedure of DNA identification for the use of disaster in the future, which includes preparation works, samples collection, samples storage, DNA extraction, typing, data analysis and interpretation of results. Some experiences and problems about the DNA identification are also discussed.
