Avuncular DNA Test

Avuncular DNA Test

Price: R4995
Testing: Child and alleged aunt/uncle
Timeframe: 5-7 working days from receipt of samples at the laboratories

The lab cannot perform this test if the aunt / uncle is NOT a full sibling to the alleged father in question.

Would you like to determine whether you are the biological aunt or uncle to a niece or nephew? Are you looking to establish a paternal or maternal relationship but are unable to obtain the required DNA samples from the mother or alleged father? International Bioscience’s avuncular DNA test allows clients to get these answers without the involvement of parents – through the DNA samples of an aunt or uncle you can indirectly confirm the paternity of the child.

We suggest you return samples by courier directly to our office because the local postal system has proved unreliable and we cannot be responsible for samples that do not reach us.

We strongly suggest including the sample of a known parent to provide stronger results.

Science and Results Behind Avuncular Testing

If the test is being carried out to determine a paternal relationship, including the mother’s DNA will help provide more accurate results. This is because having the mother’s DNA sample will allow us to eliminate the genes from the child in question that were inherited from the mother.

Our results will give you the probability of the relationship, where we usually take a result greater than 80% as being indicative of the existence of a relationship and less than 20% as being indicative of no biological relationship. Test results are intended to provide a statistical likelihood that gives evidence to support the tested relationship in question. Providing additional parties to be tested (for example, a known parent’s sample) or performing direct relationship testing may provide additional evidence.

It is important to note that while parents and children share half their genes, children only share one quarter of their genes with aunts, uncles or grandparents, making this kind of testing less accurate than testing parent-child relationships. Nonetheless, it will provide a numerical probability for the alleged family relationship. If you have any queries regarding results or the Avuncular DNA Test in general, please do not hesitate to contact us directly.

Note: We can only guarantee standard result turnaround time when testing takes place solely using oral swab samples. Using a fornsic sample for your test may lead to an increase in turnaround time.

Sample Collection For Avuncular Testing

International Biosciences supplies you with a home sample collection kit which can be used for self-sampling in the comfort of your own home. You can collect your DNA samples using the mouth swabs we provide in our kit. You will have 4 swabs for every test participant with swabs for up to 3 people. The swabs are found in colour coded envelopes and each test participant is allocated a specific colour to make things as easy as possible.
