Since only a few cells are needed for a useful DNA sample, the list below identifies some areas at the crime scene or on the victim that may contain valuable DNA evidence. Even though a stain cannot be seen, there may be enough cells for DNA typing. Furthermore, DNA does more than just identify the source of the sample; it can place a known individual at a crime scene, in a home, or in a room where the suspect claimed not to have been.

The forensic testing involves properly identifying, collecting, and preserving DNA evidence and use it as a powerful a tool for identifying the suspect. Many types of biological samples can be used to obtain a DNA profile for the purpose of matching to a donor or suspected individual.
Biological fluids (such as blood, semen, saliva) that contain cells can be used, even if dried or frozen. Only a very small amount of sample (in good condition) is needed to perform the DNA test. Small bits of cells (under the fingernails, on cigarette butts, on the rim of a drinking container), tissues, or a single strand of hair with the root intact may be sufficient.
