AlphaBiolabs is proud to provide MOJ accredited DNA testing to carry out parentage tests as directed by the Civil courts in England and Wales under Section 20 of the Family Law Reform Act (1969). In addition to Family law courts, our DNA relationship testing results are also accepted by the Child Support Agency and UK Visas and Immigration Service. AlphaBiolabs is listed on the Gov.UK website and has been working in the legal sector for over 15 years.

DNA testing is the most scientific and accurate way to prove that two or more individuals are biologically related. AlphaBiolabs has a wide range of legal DNA tests, including paternity, maternity, sibling, twin (zygosity), grandparent, aunt and uncle, and Y chromosome. All can be used for legal cases, applications and appeals, and results are provided with an unprecedented turnaround time.

How are samples collected for MOJ accredited DNA testing?

No blood samples are needed for legal DNA tests. Swabs are used to painlessly collect cheek (buccal) cells from the inside of the sample donor’s mouth.

The DNA sample needs to be collected by an approved sample collector, a nurse or another medical professional. There are strict guidelines to follow and the sample collector needs to maintain chain of custody conditions to ensure validity of the test and avoid any suspicion of fraud. Under these strict collection conditions, there is no chance of the sample being interfered with and the results are therefore admissible in a UK court.

An AlphaBiolabs sample collector can collect a DNA sample from an address of your choice, which could be a solicitor’s office or a client’s home, or at one of our nationwide Walk in Centres. Alternatively, a GP or medical practice could collect DNA samples (may be a fee involved).

How are MOJ accredited DNA tests performed?

When the samples are returned to our laboratory, our geneticists extract the DNA from the cheek cells. Our laboratory is one of only a few accredited to test up to 35 DNA Short Tandem Repeats (STR) markers as standard; most relationship tests are performed using only 16 STR markers. STR markers 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.

AlphaBiolabs performs all DNA tests twice so you can be confident of getting accurate results. Results of legal DNA tests are provided next day as standard, or even same day if time is critical.
