Genetic Reconstruction Test

A genetic reconstruction test is designed to establish if a child is biologically related to direct blood relatives on their father’s side of the family. The test is performed when the father in question cannot be directly involved in the test and a direct father-child paternity test cannot be carried out.

  • How do i decide which relationship test I need?

    There are many relationship tests available and deciding which test is most suited can be difficult. But this is where our customer support team come in – we are here to guide you and provide you with the test most suited to your individual case. Just call us and we will discuss your case. Keep in mind the following:

    1. What exactly do you need to find out?
    2. Who is available for the relationship test?
    3. Are they willing to take part in the test?
  • When do I use a sibling DNA Test?

    The DNA sibling test can be used when alleged siblings wish to determine whether they are full siblings, half siblings or unrelated. In cases where siblings want to know whether they are half or full siblings, the sample of a known parent is not required. However, when testing for half siblings, or unrelated siblings, the inclusion of the sample of a known parent (normally the mother) is recommended to strengthen the results of the test.

    The following options are also available depending on the sex of the people being  tested:

    • Do a Y chromosome test if siblings are male and want to determine whether they share the same father. This test will clearly establish male lineage. For more information on this test visit our Y chromosome testing page.
    • An X chromosome test is used if siblings are female, have different mothers and want to know if they share the same father. Visit our X chromosome testing page for further information.
    • A MtDNA test  (Mitochondrial DNA test) can be used if siblings are male and female and want to determine maternal lineage. Visit our MtDNA testing page for more information.
  • How long do relationship test results take?

    Not all relationship tests have the same turnaround time. Some tests take long than others. Most of our relationship testing services, including grandparentage, aunt/uncle and Y chromosome testing have a turnaround time of 5- 7 working days. X chromosome testing and mitochondrial DNA testing have longer turnaround times.

  • How are relationship DNA testing samples collected?

    Relationship DNA testing samples can be collected with our kit – whenever possible we suggest using this kit. Inside your kit you will find oral swabs, consent forms and instructions. If you cannot collect samples using oral swabs, for example if a relative is not available for the test, you can send us a forensic sample such as hairs, nails, toothbrushes or garments.
