DNA Fingerprinting

Parentage Testing, Paternity Test

Results

DNA fingerprinting is a test to identify and evaluate the genetic information, called DNA (deoxyribonucleic acid), of a person's cells.

DNA samples can:

• Determine who a person's parents are (establish paternity). Tissue samples from two people can also be compared to determine how likely they are to be blood relatives.
• Determine whether a suspect was present at a crime scene, by comparing DNA from the scene to the DNA of the suspect.
• Positively identify a body. Bone and hair samples can be used to identify a badly decomposed body.
