Accuracy

DNA tests are known to be 99.9 percent accurate, so they are about as accurate as one could hope for. This makes them pretty much watertight when it comes to making identifications, confirming paternity, or aiding criminal proceedings. There are different types of DNA testing used, and in different ways. For example, in forensic DNA testing the tests can be performed on the following:
- Dried blood stains
- Dried Semen stains
- Dried stains on underwear
- Saliva stains
- Tests on hair (with root attached)
- Skin scraping tests
- Tissue tests
- Bone testing
- Dental testing
- Testing on other biological matter
