A sibling DNA test is done to determine the statistical likelihood that two siblings share the same biological parent. This means that with this test we are establishing a genetic relationship between alleged siblings and a parent without testing the DNA of that parent. We offer our sibling DNA test starting at $699 with results ready in just 5-7 working days from the receipt of samples at the laboratory.
Our grandparentage DNA test is ideal in situations where the alleged father is unavailable for testing (for example if he is deceased) and the alleged father’s parents are willing to be tested to determine whether they are the true biological grandparents of the child.
Avuncular DNA testing (or aunt-uncle DNA test) determining whether an individual is the biological aunt or uncle of another tested person. This type of DNA test is often used to confirm indirectly the biological relationship between an alleged father and their child. By testing the brother or sister of the alleged father it is possible to understand if there is a biological relationship with their nephew or niece, hence indirectly providing answers to the question of paternity.
Do you need to establish the paternity of a child but are unable to carry out a paternity test? In such cases, a genetic reconstruction test is a great way of establishing paternity without the need to directly include the father’s DNA sample.
A maternity DNA test proves the biological relationship between mother and child. Our test is based on the analysis of 21 different genetic markers. The test starts from $425 for testing of one mother and one other person. Maternity test results are ready in only 5-7 working days commencing from the receipt of DNA samples at the lab.
Our mitochondrial DNA test is used to determine whether two or more people share the same maternal line. The cost of the MtDNA mitochondrial DNA test is $799 and includes the testing of 2 people. The turn-around time is 14-16 business days starting from the day your samples are received at the laboratory.
Twin DNA testing will determine if your twins are identical (monozygotic) or fraternal (dizygotic). homeDNAdirect’s twin DNA test provides you with a result that is 100% accurate. Results of your twin DNA test will be ready in just 5-7 working days from receipt of samples at the laboratory.
Y chromosome testing is used to determine if two or more males share the same paternal lineage and provides a very accurate result. The test starts at $699 with your results ready in 5-7 working days.
The X chromosome test is done when two females want to establish whether they share the same biological father. You can carry out an X chromosome test is you are two or more females and wish to know whether you share the same biological father. The X chromosome test for two siblings is offered at only N/A. Your results are ready in 15 working days from the receipt of the samples at the laboratory.
Why carry out a relationship test?
Generally, relationship DNA testing is a means of establishing paternity in cases where the father is not available and therefore, a straightforward paternity test is not an option. In such cases a grandparentage test or an avuncular DNA test can substitute a paternity DNA test. Siblings may also do a sibling DNA test, which will establish the extent of the sibling relationship: half siblings, full siblings or not siblings. The below are the relationship DNA tests we offer. This said, no relationship test will provide the same conclusive results that can be given in a home paternity test.
What will the results of a relationship test tell me?
This is not a clear-cut question with a single answer as different tests will give you different answers and not all tests are equally accurate. Some tests might just give you a probability of relationship and others might give you a definite yes you are related result. Again, for more information and details about any of our DNA tests, you can contact our team who will give you all the information you need.
How do I go about deciding on the type of test to carry out?
When you look through our range of relationship testing services, you will probably immediately know which one you require as soon as you skim the first sentence. However, we can give you 2 basic questions to help you decide on your test:
- What do you want to establish?
- Who is available for testing?
What you wish to establish refers to what you hope to find out with the DNA test result. Have a clear question in mind, for example “I want to know if this woman is my biological grandmother” or “I want to find out if my brother and I share the same father”. This will help decide if you need a siblings DNA test, avuncular test etc.
Who is available for testing is crucial and an often overlooked factor when deciding on a relationship test. You may want to know whether you and your brother share the same father but is your brother willing to submit his sample? homeDNAdirect suggests you contact our customer support team to help you decide on the best relationship test.
