Paternity Testing Explanation

DNA (deoxyribonucleic acid) is the genetic blueprint that determines an individual’s biological characteristics. Deoxyribonucleic acid (DNA) molecules serve as the storehouse of genetic information in encoded biological instructions passed on from parents to offspring. DNA is to be found in every nucleated cell of the human body. Upon conception, a child inherits 50% of their DNA from his mother and 50% from their father. The distinctive blend of DNA, once analysed, will match that of the biological parents.

Paternity test or testing can conclusively establish the identity of a particular man as the biological father of an alleged child. The process involves collection and subsequent examination of DNA from tissue or body fluid sample of the child and man in question.

Paternity test or testing through DNA analysis is the most accurate way of establishing beyond a trace of doubt the relationship between a child and alleged father.

Paternity test or testing is the most reliable method of identifying the biological relationships between parents and child. Many older methods also exist in medical science such as ABO blood group testing, and analysis of various other enzymes and proteins, but DNA paternity test or testing is by far the most advanced and accurate method to determine the possibility of the biological parent child relationship. In a paternity test, result is 0% when the alleged father is not biologically related to the child, and the likelihood is typically 99.99% when a person is biologically related to the child.

When a paternity test confirms that a child's DNA does not match against the alleged father, he is excluded 100% as the biological father of the child. When the child's DNA does match against the alleged father, we can prove a probability of 99% or greater for paternity. To determine probability of paternity, human cells are first extracted from those being tested. For in-home sample collection, cheek cells are collected from inside of the cheek with a buccal swab. Once with the laboratory, these cells are expertly separated from the swab. The DNA from these cells is carefully extracted, and divided into sample fragments with enzymes. These fragments are positioned into a gel matrix, where an electric current sends the fragments across the gel. Later in the process, these fragments are subjected to a labelled DNA probe.

This probe recognises and binds to a unique segment of the person's DNA. Where this probe binds to each person's DNA is essential for confirming relationships.

A film is developed that will establish black bands where the probes bound to each individuals DNA. The pattern of a child is distinctive - half matches the mother and half matches the father. If it is confirmed that the band patterns of the alleged tested father DO NOT match that of the child, that person can be conclusively excluded as the child's father. If the patterns DO match, the probability of paternity begins to increase. This entire procedure is repeated several times independently in our paternity test. Numerous different probes, producing many different band patterns, are established. The more probes that are used; the more definitive the concluded results can be.

DNA testing or paternity testing is extremely scientific and very accurate. DNA Diagnostics Centre is able to perform this highly expert testing at a very affordable price because of an extremely skilled laboratory and personnel. By choosing DNA Diagnostics Centre to complete your DNA test you can rely on fully certified and high accuracy DNA testing or paternity testing result.
