Paternity Testing for Peace of Mind

Paternity testing from AlphaBiolabs works by comparing markers from a child, mother and alleged father, it is possible to establish whether an alleged father is the biological father of a child with a probability of paternity routinely in excess of 99.99999999%.

Children inherit half of their DNA from their father and half from their mother. If a man shares certain DNA sequences with a child then there is a chance the man is the biological father of that child.

Paternity Testing Services

Peace of mind Paternity Testing

Our paternity test is designed to give you the peace of mind you deserve. This paternity test is used purely for your own information to give you the answers you need regarding the paternity of a child. This type of paternity test cannot be used in a UK court.

Legal Paternity Test

Our legal paternity test is designed for use in UK civil courts and can be used for updating legal forms. We have been accredited by the Ministry of Justice for our legal paternity test as a body that may carry out parentage tests directed by the civil courts in England and Wales under section 20 of the Family Law Reform Act 1969.

Immigration Paternity Testing

Our immigration paternity test is designed to help you provide evidence to the immigration authorities that you have a biological relationship with a British citizen. Our immigration paternity test is fully accepted by the UK immigration authorities and the UK Border Force.

Paternity Test Questions?

If you have any question regarding our home paternity testing then visit our paternity test frequently asked questions page or call us on: 0800 170 1200 to speak to one of our DNA paternity testing experts.

Some of the most common question we get asked are below:

What does “not excluded as the biological father” mean?

It means that the tested man (alleged father) has the DNA profile expected of the biological father. Therefore, the paternity test result is consistent with the hypothesis that the tested man (alleged father) is the true biological father of the child.

What does “excluded” as the biological father mean?

It means that the tested man (alleged father) does not have the expected profile required to be the biological father. He is therefore highly unlikely to be the true biological father.
What does the “probability of paternity” mean?
This is the percentage likelihood that a man with the genetic markers (alleles) of the alleged father is the true biological father of the child as compared to an untested and unrelated man of the same ethnic origin.

How is the paternity test done?

The test compares fragments of highly variable DNA, called Short Tandem Repeats (STR). Through a series of chemical reactions, DNA from each individual is extracted. Using a technique called PCR (Polymerase Chain Reaction); fifteen STR markers from different chromosomes of the individuals tested are copied. The products of the PCR are separated and measured to obtain a DNA profile.

One-half of each person’s DNA information comes from their mother and the other half from their biological father. By comparing the DNA profiles of the child with the mother, it is possible to establish the shared STR markers between them. The child’s STR markers not found in the mother’s profile must therefore come from the biological father.

If the alleged father’s profile shares common STR markers with that of the child, then he is not excluded and may indeed be the true biological father. A statistical analysis is then carried out to calculate the probability of paternity. An alleged father is excluded as the biological father if STR markers found in his profile are not shared with the child. The Test Results Table lists each STR marker tested with the probability of its occurrence in the general population.

What is the paternity index (PI)?

The paternity index compares the likelihood that an allele was passed on by the alleged father to the child, to the probability that a randomly selected unrelated man of similar ethnic background has passed that same allele on to the child.

What is the combined paternity index (CPI)?

This ratio indicates how many times more likely it is that the results of the DNA analysis would have been obtained given that the tested man (alleged father) is the true biological father of the child submitted rather than an unrelated man picked at random from the same ethnic population. The CPI is based solely on genetic evidence and is determined by multiplying the individual PIs for each marker tested.

Who will receive the results?

The test report(s) will be given to the person(s) nominated on the DNA Profiling Consent Form, for whom everyone tested has given consent, and other authorised persons, where appropriate.
What happens to the DNA after the test is carried out?

The extracted DNA is destroyed by incineration three months after the report has been sent out.

What happens if I want to take my results to court?

If you need the results of the test for court or for other legal purposes, such as changing a birth certificate, then you will require our Legal Testing Service. Contact one of our friendly Customer Service advisors for further details on 0800 170 1200.

How our Paternity Testing works

Our paternity test works by comparing a child’s DNA profile with that of an alleged father (and ideally the mother as well). Because a child inherits half of his or her DNA from each biological parent, such a comparison reveals whether the child has inherited DNA from the alleged father who is being tested.

UKAS Accredited Paternity Testing

We go to great lengths to achieve UKAS accreditation, the strictest form of accreditation in our industry. AlphaBiolabs is UKAS 17025 accredited meaning that you can have confidence in our test results as our own testing laboratory has been independently assessed and authorised by industry experts from the UK Accreditation Service (UKAS).

Our Paternity testing laboratory is UK based

There are a lot of websites on the internet who provide paternity testing and we have found that most promote that they are UK based. In truth, your paternity test samples could end up anywhere in the world. Although this may seem acceptable, can you really be sure that the laboratory testing your DNA samples conforms to strict best practice and uses the most advanced techniques to ensure that your test results are correct?

AlphaBiolabs is fully accredited to perform DNA paternity testing. Our laboratory goes through strict third party testing to ensure that the results we provide are as accurate as modern science allows. Our laboratory is based in North West England so you can be sure that your DNA paternity test samples are staying within the United Kingdom.

Four easy steps to use our paternity test

With a ‘Peace of Mind’ paternity test the DNA samples are taken at your convenience in your own home.
Once you have purchased your DNA paternity test, there are just four simple steps:

  1. Complete and sign all documentation provided. Included with the kit are consent forms, which must be signed and sent back to AlphaBiolabs with your DNA samples.

  3. Place all swab envelopes and completed forms in the large envelope and post back to AlphaBiolabs using the correct postage.
