Learn About the Different Types of DNA Testing Available

Due to TV shows and popular culture awareness of DNA testing has increased with members of the public. More and more DNA tests are carried out in the fields such as family law, criminology, biotechnology and biomedicine. One of the main reasons for this is because it’s possible to ascertain biological lineage as well as genealogical links from the test to help settle any disputes which arise amongst family members. DNA Testing this can also help to solve crimes since criminals will be identified from the evidences discovered at the crime scene from their DNA.

In most cases, people require a DNA test in order to establish whether or not they are the true biological father or even mother of a child. However there are many reasons why someone would need to make use of this testing method, such as siblings who after being separated at birth who need to determine if one is related to other.

It is important to note that DNA testing is possibly the most accurate method around that could be utilised for identification purposes due to the nature by which results will be extracted.

Generally a DNA test will be extremely accurate since you will not find two people with the exact same genetic make-up. Of course, there are genetic commonalities between children and their biological parents, but the children will still have their unique genetic features. This will be the ideal solution to identify persons in certain situations since there is such an advanced level of conviction involved once the DNA is tested.
Are there are different types of testing available?

There are several different types of DNA testing available depending on your needs. First let’s look at the differing testing procedures.

There are two distinct types of DNA test available. The first is a Court Admissible DNA test. This is whereby the collection of the samples is performed through a controlled chain-of-custody procedure with a third party to act as a witness and verify the authenticity of the samples.

For example a nurse will travel to your home with the DNA test kit, will ask for proof of identification, and then take the DNA test from you. They may also take copies of your identification and the DNA sample will be sealed in a tamper proof container to wait DNA testing. Then at the DNA testing laboratory your sample will follow a chain of custody meaning that anyone who handles this sample must record every aspect of its journey through the testing procedure.

Then there is also the ‘ Peace of mind’ DNA test whereby a DNA testing kit will be sent to you through the post and you will be responsible for collecting your own samples and sending them back through the post. This type of test you cannot use in a court of law as the laboratory has no way of knowing who the samples have been taken from.

Both these types of test are extremely accurate providing the DNA samples are taken correctly.

The types of DNA testing

Paternity testing

You could have a need to get a paternity test if you which to establish the biological relationship between an adult and a child. So for example if the alleged father of a child is refusing to acknowledge his paternal responsibilities for the child as he thinks he is not the father then a paternity test can prove or disprove this.

Grandparent DNA tests

Grandparent DNA tests can be used to establish a biological relationship between an individual and one or both of their alleged grandparents. So for example a child may have lost both parents and the Grandparent wants to take custody for the child in question, they will need to prove that they have a biological relationship with the child.

DNA Maternity Test

A DNA Maternity Test is suitable if you want to demonstrate the existence of a biological relationship between an alleged mother and a child. For example if a child is adopted at a young age and later in life the child seeks to have a relationship with his/her mother. It may be used to confirm that biological relationship.

Sibling Test

Half Sibship analysis is an excellent way to determine if you share 1 parent with another individual. Full DNA Sibship analysis is an excellent way to determine if you share both parents with another individual.

This type of analysis is ideal to siblings who may have been separated from an early age and who wish to receive confirmation that they may be biologically related.
