Are you biologically related to your grandchildren? Are you biologically related to your grandparents? homeDNAdirect South Africa offers grandparentage testing which will confirm whether or not a genetic relationship exists between grandparents and grandchild/ grandchildren.
A genetic reconstruction test is used to prove the paternity of a child in instances where the alleged father is not present for testing. In such cases we can use advanced DNA testing methods to determine whether the untested alleged father is the biological father of the child by testing the alleged father’s blood relatives.
Establish the biological relationship between aunts and uncles with their nieces or nephews with an aunt/uncle DNA test. This test is sometimes called an avuncular DNA test. Avuncular DNA testing starts from as little as R4995 for the testing of two individuals (aunt or uncle with a niece or nephew)*.
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 is used as biological proof of maternity between mother and child. homeDNAdirect South Africa offers maternity testing services priced at only R2395. This includes the testing of the mother and one child. Your results are ready in 5-7 working days from the moment we receive samples. Standard results are sent to your chosen email address.

Males can carry out a Y chromosome test between them to confirm whether they have the same father or not. This test is extremely accurate due to the very low mutation rate of the Y chromosome. The Y chromosome test is offered at R4995. The results are ready in 5-7 working days.
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.
