Sibling DNA testing will establish whether siblings share 1 parent, both parents or have no biological parents in common. A sibling test can be done between siblings of both sexes.
Grandparentage DNA testing will establish the probability of the tested grandparents being the biological grandparents of their grandchild child. Grandparents might need this DNA test if their grandchild’s alleged father is dead or unavailable for a DNA test and there are doubts about the paternity 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.
Maternity DNA testing is the only scientific means of determining that a biological relationship exists between an alleged mother and her child. Maternity tests will show results with an inclusion of maternity of 99.99% or higher and a 0% inclusion rate should the tested mother not be the child’s true biological mother.
Twin DNA testing will determine if your twins are identical (monozygotic) or fraternal (dizygotic). homeDNAdirect 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 (or Y-STR testing) is a reliable means of establishing whether alleged male relatives are really biologically related through the same paternal line. Cousins, uncles, nephews, siblings and so forth may all potentially be interested parties in a Y chromosome test. All males carry a Y chromosome which is inherited from their father and is passed down from father to son, from generation to generation.
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.
