DNA Testing Options
A DNA paternity test is used to resolve any questions or doubts relating to the paternity of a child.
A paternity test works by comparing the DNA profile of a child with the DNA profiles of his or her mother and alleged father. If the child’s mother is unavailable for testing, we can often perform a motherless paternity test.
Many of our clients use legal paternity test results to settle family law matters (such as child care proceedings, child custody and visitation disputes and adoption), resolve inheritance disputes, and satisfy immigration requirements.
A DNA maternity test is used to determine whether a woman is the biological mother of a child.
Like a paternity test, a maternity test works by comparing the DNA profile of a child, the alleged mother and, when available, the child’s father.
Our prenatal DNA test is an accurate and non-invasive way to determine paternity prior to a child’s birth.
A mouth swab is required from the alleged father and a blood sample is required from the arm of the biological mother. Both of these samples will be collected by our professionally trained Sample Collectors. After profiling the mother and foetus, we are able to compare the markers against the alleged fathers’ DNA.
The test analyses free-floating foetal DNA from the mother’s plasma and compares it to the mother’s DNA profile. Once the foetus’ profile is determined, it is then compared to the alleged father to determine paternity.
The mother must be at least 8 weeks pregnant as per confirmation from a medical professional and testing is unable to be undertaken on multiple pregnancies (i.e. twins and triplets).
Analysis results for prenatal DNA tests will be provided in 8 working days or less.
Siblingship testing can help two alleged siblings verify whether they are full siblings or half siblings.
A grandparent DNA test can determine whether a child is biologically related to the alleged grandparents. A grandparentage test is based on the fact that a child inherits half of his or her genetic profile from each biological parent. When one of a child’s parents is unavailable for testing, we can look to the grandparents to determine whether they contributed DNA to the child’s genetic profile.
Avuncular Testing (Aunt/Uncle)
A legal aunt-uncle DNA test is taken to determine if a child is the biological niece or nephew of the alleged aunt or uncle. The avuncular test is a viable option when the alleged father or mother is unavailable for testing and the only available relative is a brother or sister of the alleged father or mother.
Cases that involve in-direct relationship testing including Avuncular, single Grandparentage and Siblingship (full–siblingship and half–siblingship) tests will only provide a statistical likelihood that gives evidence to support the tested relationship. A test of this nature will not directly exclude the relationship. The test merely gives the odds of the relationship based on the purported relationship and the systems tested.
The DNA testing laboratory used by Lextox holds ISO/IEC 17025 accreditation and is Ministry of Justice accredited to perform parentage tests directed by the courts in England and Wales under section 20 of the Family Law Reform Act 1969.
