DNA stands for deoxyribonucleic acid and is found in almost all the cells that make up the human body. DNA contains a code that decides what characteristics a person will have. Samples of DNA can be used to see if people are related and are used to prove or disprove whether someone is the parent of a child. A DNA test can also be taken from a blood sample or some cheek cells from the inside of the mouth using small sponge on a stick. The test is quick, simple and painless.
DNA testing can either, prove 100% that a person is not a child's parent or show a 99.99% probability that a person is a child's parent.
