DNA Relationship Testing

The definitive method for determining whether genetic relationships exist between related individuals is by doing a DNA Relationship Test.

DNA testing is accurate and reliable. A relationship test may not always tell you what the relationship is between two people but it will tell you the probability of being genetically related or not.

In cases where the alleged father is absent or deceased father, one can still establish whether he is the biological father or not by testing other members within the family related to the father;
therefore one can test the alleged father’s parents via the grandparentage test or test to see if a biological relationship exists with the alleged aunts and uncles via an avuncular test. The dna test can establish if a biological relationship exists and thus, by extension, that the child is the alleged father’s biological one. Siblings can also do a sibling DNA test to establish paternity. We offer Relationship tests starting at the price of €385.

Given the extensive list of tests available, at homeDNAdirect Ireland we have a specially trained customer care department that will advise you the test most suited to your needs.

What types of Relationship DNA tests are there?

• Siblings DNA test: A sibling DNA test will establish if two or more alleged siblings are full siblings, half siblings or not related. A sibling test can be performed through different testing methodologies based on the sex of the parties and nature of their relationship.
   
  
• Avuncular DNA test: testing is performed on the siblings of the alleged father (aunt or uncle of the child) to determine if a relationship exists with the child.
   
  
• Grandparentage DNA test: will show whether two alleged grandparents are biologically related to their grandchild or not.

Different Methodologies for performing Relationship tests

• STR testing: this type of test finds genetic markers in common between two individuals, commonly a brother and sister, to determine their level of relatedness.
   
• Y chromosome test: this type of test is done between related males to see whether they are biologically related.
   
• X chromosome test: this DNA test is done between two females to see whether they are biologically related.
   
• MtDNA test: (Mitochondrial DNA) this type of DNA testing is used to establish whether two persons are related from their mother’s side

Sampling your DNA and more information about the test

As with most of our tests, we recommend that dna is collected using the standard mouth swab as it is absolutely painless, easy to use and has a high success rate. Our sample collection guide will help you understand how to collect your DNA sample.
 
If it is not possible to use our swabs, you may however choose to send in a discreet sample, which might include cigarette ends or a used Kleenex. Please ensure you seek our advice should you be thinking of using one of the many discreet samples that our laboratories test.
 
The results of your Relationship DNA test will be ready in just 5-7 working days. You may wish to take advantage of our express testing option and get your results in just 2 working days.
