What is DNA?
DNA is Deoxyribonucleic Acid and is the genetic material that is found in the nucleus in most cells in the human body (nuclear DNA). DNA is also found in the energy-producing mitochondria of a cell (mitochondrial DNA).
Nuclear DNA is inherited in equal portions from a person’s mother and father. Therefore, each person shares 50% of their DNA with their mother and 50% with their father. Full biological siblings also share DNA with each other. To a lesser degree, individuals also share DNA with other relatives such as aunts, uncles, cousins, etc.
Mitochondrial DNA is inherited maternally. Therefore, every child (male or female) of a particular woman has an exact copy of his/her mother’s mitochondrial DNA.
DNA on the Y-chromosome (present in males only) is inherited paternally. Therefore, all males who share the same paternal lineage would be expected to have the same Y-DNA profile. Back

Are there different tests for different uses?
There are tests that are legally admissible in court and there are self-collected or home tests that are not admissible in court. The "sample collection," "lab processing" and "PhD analysis" are exactly the same. The difference between the tests is that the legally admissible test is AABB approved and requires an impartial third party witness to the collection and chain of custody procedures. Back
How are the samples collected?
The inside of the cheek of each person being tested is gently wiped with a soft cotton swab. Because almost every cell in a person's body contains his or her unique DNA, swabbing a cheek is a safe, easy way to collect the sample. Each sample is then sealed in its own envelope, labeled for identification purposes and sent to our lab for processing. Back
How reliable are the results?
Our highly accurate DNA paternity testing procedures and technology virtually eliminate the chance of false negatives or false positives due to random chance, racial similarities, or a non-paternal blood-relative relationship.
We can deliver accurate conclusive results even in difficult cases, such as those involving incest or where the alleged fathers are related to each other - providing evidence that can quickly streamline court proceedings and facilitate pretrial settlements. If required, Orchid Cellmark can also offer skilled expert witnesses to provide depositions and expert testimony in court. Back
