Used in high-profile criminal investigations and paternity cases, deoxyribonucleic acid, commonly known as DNA, testing has now been popularized to prove relationships between individuals. The evolution of the test in past years has turned DNA testing into a popular tool for determining ancestry. The test also helps in determining if two people are related or descend from the same ancestor. Although DNA has been around for many years now, the cost has dropped enough to be affordable to average individuals interested in tracing their roots.
Home DNA test kits can now be ordered over the Internet or through the mail at a cost of less than $ 300 per test. The kit usually contains a swab or mouthwash that can help collect a sample of cells from the inside the mouth.
The samples can be posted back via mail and within a span of one month an individual can receive a series of numbers that represent key chemical ""markers"" within his DNA. These numbers can then be compared to results from other individuals to help determine ancestry.
This small amount of blood or cheek swab allows the testing of newborns as well. Paternity tests can also be conducted during pregnancy. These samples are compared to trace any similarities and then sent to the laboratory for verification. The results of a DNA testing are accurate and confidential.
If the results of the DNA testing are to be used in a court of law, and require a legal standing, a home DNA test is not usually admissible. A much more rigorous approach in verifying the source of every sample is required. The process of obtaining the samples is witnessed and fully documented, including taking photographs of all the parties associated with each sample. This continuity is maintained with the laboratory environment, and allows an expert witness to provide an opinion in court, as to the relevance of the test results.
What makes DNA testing so popular is its ability to be performed not only in DNA Test Laboratories, but also in the privacy of their own homes. The search for biological parentage can be an emotional time for most people. Some find it rather uncomfortable to let friends know they are undertaking a DNA paternity test. Some also find it awkward if their surrogate family, the one who has raised them and love them all their lives, find out that they are undergoing a DNA paternity test to prove or disprove relationships and parentage!
Home DNA test kits are fairly easy to use, employing the buccal swabbing technique to obtain DNA samples. DNA collection is done within a few minutes and is virtually painless and safe. These tests also come with clear and easy to follow instructions which clients must follow to obtain accurate results. The samples are then sent through mail for analysis.
Results of home DNA test kits are mailed back to the approved people as stated in the authorization forms enclosed in the kits. Test results are kept in high confidence and are released only to the authorized people who were tested and to other client-approved individuals, such as lawyers or doctors.
Samples are generally mailed back to the testing company to carry out a full DNA analysis, generally resulting in a report within a few weeks. The report should provide a clear unambiguous outcome to answer the question as to the biological relationship of the putative father to the child.
Percentage of Inclusions and Exclusions A better home DNA test kit should come from a DNA testing company that offers 100% exclusions of paternity and 99.9% inclusions of paternity. In simple layman's term, exclusion percentage shows the tester who can not be their fathers, and inclusion show who can possibly be their father.
