DNA Testing FAQDNA Testing Frequently Asked Questions
What is DNA?
This information is used to develop an individual in a particular way, for example their physical appearance and attributes.
As DNA is in almost all living cells it can be found in saliva, hair and blood for example. These are some of the most common sources that DNA testing samples are analysed from.
What sorts of DNA tests are there?
These tests produce the most accurate results when the child, the alleged father AND mother are all tested. But there are other ways that the probability of the paternity of the child can be deduced without the need to test all three of these individuals. These include Y chromosome testing and aunt and uncle testing (AKA avuncular testing) to name a few.
DNA testing usually refers to relationship testing, in which an individual’s likelihood of a relationship with another individual can be determined. This could be conducted for many reasons, including establishing that a person is related to a UK citizen for immigration purposes, or to determine a person’s ancestry.
DNA testing is commonly involved with solving crime. We are primarily a DNA, Drug & Alcohol testing laboratory and we do not claim to be a forensics laboratory but we can use workplace testing to help reduce crime or eliminate criminal activity within your business if required. DNA testing is also associated with determining the likelihood for someone to inherit genetic diseases or to help develop the treatment of genetic diseases. AlphaBiolabs do not currently test for such purposes.
What is the difference between a peace of mind test and a court approved test?
It will not be admissible in court, as proof of relationship for the Child Support Agency or for immigration purposes for example. It is still an extremely accurate form of testing and if you only need it for your own knowledge then it can be a more cost-effective form of DNA testing.
A ‘court approved test’ is a test that can be used as proof of relationship in legal cases. The difference here is that the sample will have been collected by a third party, who can certify that the person who is required to be tested is definitely the person who is actually being tested.
This is done in a way so that all the required procedures of a legal DNA test are followed during the sample collection process. The analysis process and results are not necessarily any more accurate than those of a peace of mind test, but it does reduce the possibility of foul-play – such as tampering and bogus sample donations (the wrong person’s sample being used due to a fraudulent submission).
Legal testing usually costs more due to the sample collection process involved, but you can reduce this cost by visiting one of our Walk-in Centres, where one of our fully qualified members of staff will collect the sample for free without the need to make an appointment.
If you require a DNA test for your own knowledge order a peace of mind test kit to use at your own convenience, any time.
If you require a court approved test then order a legal DNA test and we can arrange for one of our sample collectors to visit you at an address of your choice at a time that’s convenient to you. Alternatively, you can visit one of our Walk-in Centres
What does a DNA test involve?
These swabs will be placed in individual envelopes and sealed before being sent to the lab for analysis.
Some DNA tests do require taking blood, such as prenatal DNA testing. However, this is done non-invasively and will not disturb or harm the baby in any way as the DNA is analysed from the mother’s blood rather than directly from the baby’s. Please see (Prenatal DNA Testing) for more information on the subject.
DNA tests can also be undertaken with samples from the deceased (for example during autopsy). When this is the case all the relevant ‘qualified’ consents are required before any DNA testing can take place.
What is a buccal swab?
Do you do discreet DNA testing (AKA infidelity testing)?
However, we do not provide discreet DNA testing (or infidelity testing) in the sense of performing a DNA test without the relevant consent required. When DNA testing is conducted, some form of consent is always required and we will only conduct our services when this consent is provided.
There are exceptions where consent is not required, such as for coroners, the investigation of crime or for national security. When it comes to tests for the general public the legality of testing without consent can be a difficult area.
There are exceptions where consent cannot be given such as for young children or the deceased, but consent can usually be given by someone else such as a parent or next-of-kin.
If a DNA test is offered to the public without the need for the person being tested to consent to it, then they may be breaching The Human Tissue Act, even if it is only for peace of mind.
Do you need consent when taking a DNA sample?
There are some circumstances where consent is not possible, such as when testing children and the deceased. However, relevant consent can be given by other related individuals such as parents and next of kin.
There are some authorities that are exempt from the Human Tissue Act (see above) but these do not include companies offering DNA testing to the general public.
It is always important to provide the consent of everybody being tested when possible and ‘qualifying’ consent when it is not.
What if the person is deceased or unavailable for testing?
What is the minimum age for DNA testing?
This is because the DNA is analysed from the mother’s blood rather than that of the baby. For prenatal testing to be conducted the mother must have been pregnant for over 9 weeks .
How much does DNA testing cost?
In specific cases where GPs are needed to collect the samples they may include their own fees for the service. AlphaBiolabs states when additional fees for services are required at the point of sale (such as if you require an additional child to be tested in a paternity test) so it is clear to our customers how much they will pay overall before any payment is taken.
Other variations in price can coincide with the time you require the results. With our peace of mind tests we provide next working day results as standard and our legal testing is provided within 3 working days as standard. However, with legal testing we can also provide next working day results or even same day (8 hour) results if we receive the samples before 10:00am for an additional fee.
I cannot afford a DNA test, can I have one for free?
Can I use the results in court?
If you order a peace of mind test (a home DNA testing kit) then the results cannot be used in court. If you order a legal DNA test you will be able to use the results as proof of relationship in court, for the CMS and the Home Office for example.
When you order on the phone our friendly customer service team will always clarify with you what the tests will be used for to ensure that you purchase the correct test for your needs.
Who needs to be tested?
In most cases where a child is involved they will need to be tested, but as the procedure uses mouth swabs it is totally painless and there is no minimum age at which a child can be tested in this way. It is possible to determine a child’s paternity by DNA testing while pregnant (non-invasive prenatal testing) and this does not require a sample being taken directly from the baby. The babys DNA is analysed from the mother’s blood, so the baby is not disturbed or harmed during the procedure.
If the father is not available for paternity testing a probability of paternity can still be established using other testing techniques such as Y chromosome testing. If a DNA sample needs to be taken of someone who is deceased this can possibly be obtained during autopsy for example, but the relevant consent will need to be given before the samples can be used for this purpose.
Does the mother need to be tested for a paternity test?
The results provided without testing the mother may still have a high percentage of probability of paternity for the alleged father but testing the mother too may be the difference between providing an inconclusive or a fully conclusive result of probability. All of the tests are accurate, but when the child, alleged father and the mother are tested it can reduce the need for interpretation of results.
How accurate is the testing?
We can proudly state that our paternity testing can determine a probability of paternity of over 99.99%. Our results are extremely accurate at determining the probably of paternity. However, it is important to consider the difference between words such as ‘conclusive results’, ‘probability of paternity’ and ‘accuracy’.
To clarify, anywhere that claims that it can give 100% probability of paternity (rather than ‘accuracy’) may be being more than misleading. Be sure to look for the percentage of probability as well as the accuracy because all companies will claim to be accurate.

Does taking the sample hurt?
Some DNA tests do require taking blood, such as prenatal testing. However, this is done non-invasively and will not disturb or harm the baby in any way as the DNA is analysed from the mother’s blood stream. Please see (Prenatal Testing) for more information on this particular subject.
I am afraid of needles, can I still take a DNA test?
Is a blood sample required?
Why would I use a DNA test kit?
As long as you do not open the packaging containing the swabs until necessary the kit can be kept until you choose to take the sample. This can give you more time to organise everyone who is to be tested for example because it is designed to be used at a time that is convenient to you.
Once the samples are sent to us in the envelope provided and received at our laboratory we will provide the results the next working day so you will soon have the answers you need.
Although the kits are cheaper than legal testing they are just as accurate and are still kept 100% confidential, the differences are that the sample collection can be self-administered but they cannot be used in court (or for the CSA or immigration purposes).
Therefore you would use a DNA kit if…
- You want a great price for a DNA test for peace of mind that does not need to be used in court
- You would prefer to self-administer the sample collection process at your own convenience for peace of mind DNA testing
- You need next working day results as standard for a peace of mind DNA test
- You don’t want to order online or have the DNA testing kit sent to your address, they are available at 290 Home Bargain stores across the country
- You want 100% confidentiality with the same level of accuracy as a legal DNA test but to be used for your own knowledge rather than legal cases
How do I interpret the results/will I receive help afterwards?
However, even results with very high or low extremes of percentages can be a bit more confusing for people to interpret. Whenever you have ordered a test with us we are available to help you every step of the way.
If you require any help then you can contact our friendly team who can advise you on what the results indicate in an easy to understand manner.
What happens to the DNA sample once the testing is done?
These time frames comply with all the necessary legislation (such as the Data Protection Act and Human Tissue Act).
