Since 1990, Fairfax Identity Laboratories (FIL) has been at the forefront of DNA profiling techniques and innovations. The science of DNA profiling relies on technology that allows an individual's DNA (deoxyribonucleic acid) to be examined and analyzed.
DNA is the genetic material that we all inherit from our parents. It is considered the chemical blueprint that makes each of us unique. The one exception is identical twins, who have identical DNA. The complete genetic blueprint is found in almost all cells of the body. Thus, DNA profiling can be performed from many types of biological specimens including blood, buccal (mouth) swabs, sperm, autopsy specimens, and products of conception. DNA is composed of subunits called base pairs, with a person's DNA encoded in 6 billion such base pairs.
