Casey Randall of AlphaBiolabs answers some of the most common questions regarding relationship DNA testing for court
Relationship tests provide clarity where biological relationships are contested or unclear, for cases ranging from child custody disputes and inheritance claims to immigration and probate matters.
Parentage tests (e.g. paternity, maternity and prenatal paternity tests) are the most requested for legal purposes, providing counsel with irrefutable evidence of a child’s parentage. These tests can play an important part in cases involving child maintenance disputes or questions of parental responsibility.
Where a biological parent is unavailable or unwilling to participate in a paternity or maternity test, other family members can be tested to verify a biological relationship. This is known as complex relationship testing. Examples of these tests include sibling, grandparent and avuncular (aunt/uncle) tests.
Y-chromosome testing can also be used to confirm paternity via shared paternal lineage, while extended family testing can help verify a biological relationship between more distant relatives (e.g. cousins).
At AlphaBiolabs, we analyse up to an industry-leading 153 DNA markers for our legal DNA testing at no additional cost. This is particularly beneficial for complex relationship tests, where the chances of obtaining a conclusive result will always be lower than the more straightforward paternity or maternity tests.
Consent is a fundamental requirement for DNA testing. Any person aged 16 or over must provide their own consent. When testing a child under the age of 16, consent must be provided by a person with parental responsibility for the child.
In cases where consent is withheld, the court may issue an order mandating DNA testing. AlphaBiolabs works closely with legal professionals, providing guidance throughout the testing process, and ensuring all testing complies with ethical and legal standards.
At AlphaBiolabs, we keep full, detailed records of the testing process and ensure we maintain chain of custody and sample integrity throughout, including:
For most relationship tests, a cheek swab is rubbed quickly and painlessly on the inside of the cheek to collect cheek cell DNA. To perform a relationship test on someone who has recently passed away, alternative samples such as the deceased’s nail clippings (usually toenails) or less frequently, tissue or blood, can be used to obtain a viable DNA profile for the purposes of performing a relationship test – provided next of kin give consent for testing. These samples are typically collected by the coroner or funeral director who will complete a declaration form at the time of sample collection, maintaining chain of custody.
If a genetic profile can be obtained, a DNA relationship test can then be performed by comparing the DNA profile of the deceased person with that of a living relative to identify matching DNA markers.
With over 20 years’ experience providing DNA testing services for the legal profession, AlphaBiolabs has earned its reputation as the UK’s No.1 DNA laboratory for legal matters. Why choose us?
