DNA Fingerprinting Testing

DNA Fingerprinting is also known as DNA profiling or Genetic Fingerprinting.


DNA is a Deoxyribonucleic acid discovered in 1869 which contains the genetic instructions used in the development and functioning of all known living organisms, including some viruses.


DNA profiling is currently been used for identifying criminals or victims and for paternity or maternity tests. Also, Genetic fingerprinting is thought to be a sort of personal identifier as well.


The man who discovered DNA was a 25-year-old Swiss physician, Frederick Miescher, who worked in the laboratory of physiological chemistry of eminent scientist Felix Hoppe-Seyler.

In 1953, Francis Crick and James D. Watson worked out the first accurate structure of DNA.


  • Mother, Possible Father and Child or Children (called a trio) - The mother’s participation in the paternity test helps to exclude half of the child’s DNA, leaving the other half for comparison with the alleged father’s DNA.
  • Possible Father and Child or Children (called a motherless) - Results are equally conclusive whether or not the mother participates. Motherless tests are guaranteed to have at least a 99.9% probability of paternity for inclusions and 100% for exclusion.
  • Prenatal Paternity Testing -Paternity relationship is known before the child is born by using prenatal samples collected by an OB-GYN.
  • Umbilical Cord DNA Paternity Testing - (blood test taken at birth)
  • Viability Test - When the possible father is missing or deceased and another biological source is used.
  • Home Paternity Test - test made to answer family or personal questions and not for any legal purposes.
  • Grandparent DNA Test - If the suspected Mother or Father are unavailable, missing or deceased, both of the Paternal or Maternal Grandparents can be tested in order to determine the likelihood of genetic relationship.

Sample Collection Method

Buccal swab (rubbing on the inside of the mouth) are routinely used to collect samples. This process is quick, easy and painless. Also used in Self-collection (also known as in-home collection)

As soon as the lab receives the samples it begins isolating the DNA particles to generate a DNA Profile for each person involved in the case.

Legal DNA Test

A Legal DNA Fingerprinting Test is often used as evidence in a court of law concerning legal matters such as child support or custody cases, immigration or inheritance claims.

A Legal DNA Test is administered by an authorized laboratory or clinic that serves as a witness through documentation, making the DNA test results admissible in court.

Non-Legal DNA Test

A Non-Legal DNA Test (at home dna test) cannot be used for any legal purposes and is not admissible in a court of law as evidence.

These tests are cheaper and used by people who prefer to collect their own samples (Self-Collection or In-Home Collection) and only need the test to answer family questions, or strictly for personal knowledge.
