The higher the detection accuracy is, the greater the harmful of contamination is. DNA contamination can be divided into sample contamination and PCR contamination. It is the most difficult to treat and prevent aerosol contamination of PCR. In order to prevent pollution, dog DNA testing laboratory should be divided into several independent areas, and the researchers should strictly obey the operation rules. In addition, we should design control experiment scientifically to track pollution sources and eliminate the contamination through technical means, once the pollution occurs.展开更多
