Our Relationship DNA Tests

Sibling DNA Test
Are you really siblings? Do you share the same parents? Siblings DNA testing is ideal in situations where alleged siblings (brothers and sisters) want to confirm their biological relationship and verify if they are full siblings, half siblings or not siblings at all.

Grandparentage DNA Test
Are you the grandparents of your grandchild or grandchildren? A grandparentage DNA test using samples from the grandmother, grandfather and grandchild, can confirm with accuracy whether grandparents are biologically related to their grandchild.

Aunt & Uncle DNA Testing
An aunt-uncle DNA test (also called an avuncular test) assesses whether an individual is the biological aunt or uncle of their niece or nephew. The results will show the probability of relationship between the people tested.

Twins DNA Test
DNA testing for twins that can determine if twin siblings are identical or non-identical. So are you monozygotic twins or dizygotic twins? Our turnaround time is approximately 7-10 working days.

Y Chromosome  Test
A Y chromosome test is the ideal test to confirm a shared patrilineal (paternal) line between male relatives. The Y chromosome is inherited only by males and test results will provide you with the clear cut answer you need. Once the DNA samples are at the laboratory, you will receive your comprehensive DNA analysis report in 7-10 working days.

Maternity DNA Test
DNA maternity tests are used to establish biological relationships between an alleged mother and a child. All we need are oral swab samples. The results guarantee minimum probabilities in excess of 99.99%+ for inclusion of maternity and 100% for exclusion leaving zero doubts.

Mitochondrial DNATest
Do you need to find out if you share a common maternal ancestor? If this is your case, an MtDNA test is the right test for you. MtDNA testing (mitochondrial DNA testing) is used to determine whether two or more people have a common maternal lineage.

FAQs – Relationship DNA Tests

A DNA sibling test is used in cases where alleged siblings wish to confirm if they are biologically related. A siblings test can be carried out without the DNA sample of the known parent if, prior to testing, the siblings know they are definitely half siblings. In cases where siblings want to determine whether they are half-siblings, the sample of the known parent/s (this is normally the mother) is highly recommended to strengthen the result of the test.

A maternity DNA test helps determine the maternal lineage of the test participants. In a Maternity DNA test we  compare the DNA profile of the alleged mother and child/children to determine if their DNA matches at 50%  level.  A child inherits 50% of its DNA from each parent.
