DNA Fingerprinting is a procedure whereby the genetic information, called DNA, in a person's cells is analysed and identified.The word fingerprinting is used because, just like a fingerprint, no two person's genetic code is exactly the same.

Although less accurate than a test done on-site at a lab, the sample for completing a Home DNA Test is obtained with a mouth swab.
