A legal DNA test is an official DNA test used for legal purposes. The people taking part in the test can be verified and chain of custody of the samples is always maintained. Brashan DNA Services provides rapid, award-wining legal DNA testing to private individuals, legal professionals, social workers and the media.
The tests work by examining up to 42 Short Tandem Repeats (STR) markers, which are specific locations on a chromosome made up of sequences of repeated DNA. These STR markers are highly variable in length between individuals. Each individual has two copies of each STR marker, known as alleles: one is inherited from the father and the other from the mother. The two alleles observed at each STR marker are compared between the tested individuals. The correspondence of alleles between tested individuals provides evidence of a relationship between them. Statistical calculations are then performed to determine the probability of the tested individuals sharing a relationship.
Our award-winning legal DNA Testing follows strict procedures to maintain chain of custody, which means that our results are court-approved and are accepted by:
The DNA sample needs to be collected by an approved sample collector, a nurse or another medical professional. No blood samples are needed for the DNA test. Swabs are used to painlessly collect cheek (buccal) cells from the inside of the mouth.
We collect DNA samples from any location in Kent or Greater London. This could be at your client’s home, at your offices, or even from prisons if required. Your clients may even be able to visit one of our 11 collection centres to have their sample collected, if they live close to one. Our fully trained sample collectors follow strict procedures to maintain chain of custody, which is crucial for legal testing. Alternatively, a GP or medical practice could collect samples (may be a fee involved).
For immigration cases, DNA sample collection abroad can also be arranged directly by Brashan DNA for a fee.
DNA test results are provided next day as standard (from when the samples arrive at the laboratory). Same day results can also be made available. Our rapid DNA testing won the Queen’s Award for Enterprise in Innovation 2016.
