Genealogical DNA Test

Genealogical DNA test is performed on a person’s DNA for genetic genealogy purposes. The Genealogical Tests can determine if two people are related by testing the samples of living individuals. After being popularized by high-profile criminal cases and paternity disputes, DNA tests are today used most commonly to prove a relationship with a person. More tests have made it possible to determine ancestry as DNA is passed down from parents to children can create an unbreakable link between generations. This testing can establish genetic history or roots of an individual.

Uses of DNA Test

This test can determine whether two people are related; it can determine if two individuals have the same ancestor; it also can find out if you are related to other with the same surname as yours; it can help to establish the family tree or disprove it. The tests can provide clues to your ethnic origins.

Test procedure

A genealogical DNA test involves a simple and painless procedure of taking a cheek scrapping or buccal swab. The sample is collected from the home of the tested person and mailed to the lab that performs the test. Some labs use mouth wash or chewing gum as samples and some labs offer to store the samples for future testing.

There are two basic types of genealogical DNA testing namely mtDNA tests and Y-Line tests.

mtDNA tests

Mitochondrial DNA also known as mtDNA is present in the cytoplasm of the cell. This DNA is passed from the mother to all her children. This mtDNA is same as your mother and her mother and so on. If two people have the same mtDNA it means that the two have the same maternal ancestry.

Y Line tests

In the recent times the Y chromosome in the nucleus of DNA is used to prove family ties. Only available to makes, Y line DNA tests are used by those who share the same surname to know if they share a common ancestor. Y chromosomes are passed from father to son, creating a distinctive pattern that distinguishes the lineage of one male from the other.

The popularity of DNA tests in high profile cases has resulted in it being most commonly used for various purposes. The genealogical DNA tests are useful in establishing the relationship of two living individuals and to know if they share the same ancestor.

Forensic DNA Testing

Fingerprinting was the most accurate way to identify a suspect at the scene of a crime. But in the recent times, Forensic DNA testing that is more accurate method of identifying individual especially in connection with crime detection. Even though it takes usually several weeks to know the test results due to enormous work involved in matching the base pair sequences, it is extremely accurate and the odds of going wrong is 350 million to one.

Legal Acceptance

Forensic DNA testing is accepted as the most accurate form of scientific evidence legally. An examination of the DNA sequences of any organism can lead to the identification of its specific species.

Uses of Forensic DNA testing

Forensic DNA testing has made a big breakthrough in tracking suspects in a crime as it can match evidence left at the scene of crime accurately to identify the criminal. Persons wrongly accused of crimes can be exonerated. This testing is very useful in identifying crime victims and also catastrophe victims. This testing can establish paternity and family relationships. This testing helps in detecting bacteria and other organisms that may pollute air, soil, water and food. These tests play a meaningful role in identifying endangered or protected species to help wildlife authorities in prosecuting poachers. In organ transplant cases, DNA testing can match the donors with the recipients. Other uses include authentication of consumables such as wine and caviar and determining the pedigree for breeds of seed and livestock.

Technologies used in Forensic DNA testing

Usually, RELP, PCR Analysis, STR Analysis, Mitochondrial DNA Analysis and Y-Chromosome Analysis are the kinds of tests used in Forensic DNA testing.

Restriction Fragment Length Polymorphism, RELP is a technique that analyzes the variable lengths of DNA fragments obtained by digesting a sample with a special enzyme. Polymerase Chain Reaction PCR helps to make millions of identical copies of DNA form a biological sample. A standard set of 13 specific STR regions is used by the FBI to use the profiles from convicted offenders as evidence from crime scenes or missing persons. Other tests are useful in identifying paternity or ancestry.

DNA testing is the most accurate evidence legally accepted to identify a criminal or suspect. Forensic DNA tests are useful in saving innocent lives and victims of crime and catastrophe.

DNA Testing Cost

DNA Tests for curiosity

The DNA testing cost varies according to the type of test and for tests done out of curiosity normally cost around $200. The results of such DNA test are reported as a Letter of Opinion as the chain of custody is not verified in these cases and therefore the report is not admissible in court.

Legally binding DNA Test

If the test is required to be submitted in a court of law, which often happens in the cases of child support or paternity dispute, the cost is higher, usually in the range of USD 500 to 600. This higher testing cost for a legally binding result is because of the need to demonstrate a chain of custody for all the samples being tested.

Chain of custody & Cost

Legal chain of custody is legally accepted only when the samples are collected in the presence of a third party who is neutral. Samples should be collected at a lab, hospital or clinic where all the parties have verified their identities. This procedure and the location also determine the testing cost. But in circumstances where the sample collection is desired to be done in the privacy of homes, neutral witness is required. The prescribed forms for Chain of Custody that are intended to be produced in court are part of the testing kit. A third party should be present to supervise and witness the collection of specimen, packaging and mailing. The expert lab assistant can also testify and witness the test procedures at extra cost. The DNA testing cost depends on the above factors and the nature of information requested.

The Genetic Testing Laboratories, Inc. GTL

The Paternity Test Kit supplied by GTL costs USD 99. This home test kit comes with overnight return by FedEx free of charge. Their equipment is highly automated and yield extremely accurate results. The reduced overheads help them to perform more tests at lesser testing cost for each test.
