The dadchecksilver service is a premier DNA test for paternity testing and also for genetic information concerning other relationships. It is intended as a human identification service for the general public and is offered at two levels; a) as a personal information DNA test and b) as a test suitable for use in legal proceedings. We are highly responsive, sensitive to your needs and provide a high level of customer service. We appreciate the sensitivity of this purchase.
We offer many types of DNA testing services for the determination of human biological relationships. We are expert in immigration DNA testing, in providing DNA tests for surrogacy and also for inheritance matters.
We operate our own accredited UK laboratories and we do not send samples to other laboratories for processing. For personal information DNA testing for paternity and other biological relationships, you may order online or by telephone.
By using our own laboratories, we offer you exceptional value for money and the highest quality laboratory processing and analysis.
Please note that we do NOT carry out tests relating to distant ancestry (genealogy etc.) or for animals (e.g. pedigree testing).
chXout on the other hand, a registered trademark belonging to Complement Genomics Ltd, offers services to the non-human DNA testing market. A range of DNA testing services for animals, plants and fungi have been designed for businesses, citizen scientists and professionals alike.
We determine whether or not an individual is the biological father of a particular child by using the latest and most robust DNA testing technology. This is often referred to as a paternity test. We are also experts in establishing genetic relationships between other individuals, for the purpose of grand-parentage, sibship and avuncular testing. For example, this is often used for establishing relationships if parents are not available, possibly for use in say, inheritance matters.
Our service is based upon the fact that each and every one of us is unique. This uniqueness comes from our genetic code, which we have inherited equally from our biological mother and biological father. The “dadchecksilver” paternity test detects the presence of shared regions of this unique genetic code (we look at 16 markers), which can in turn be used to determine if individuals are related. We analyse your genetic code and the results are displayed as a series of coloured bands. We then look at these bands from both mother and alleged father to see if every band in the child is present in the parents. If so, there is a good chance that the child and parents are biologically related.
Please be aware that the “dadchecksilver” DNA test is for either a) personal information or as a separate option, b) for legal purposes. If you wish to have a DNA test for use in court, to change a birth certificate or some other reason, then you will need a test suitable for this purpose (sometimes called an accredited paternity test). This means that we have additional procedures to consider, including sampling undertaken by a third party. We will discuss this with you at the time of ordering. Please call 0191 543 6434 or e-mail [email protected] for this service.

* Quoted turnaround times are approximate
** Extra postage/courier charges may apply. Independent 3rd parties may charge a sampling fee.
For personal information tests, the price includes the kit(s) (swabs, consent forms, return postage paid envelope(s), the laboratory testing, the reporting and any telephone support that may be required.
We strongly recommend that the mother of the child is involved in any paternity testing process and there is no reduction in the price if the mother is not tested. Further donors (e.g. additional children) can be tested for £70 each.
Some people will require an extra kit or an extra report (to another address). There will be an additional charge of £12.50 for any replacement kits or reports.
For tests suitable for legal purposes, the price includes the kit(s) (swabs, consent forms, return postage paid envelope(s)), co-ordination with the sampler, the laboratory testing, reporting of the results in the format required for the legal purpose and any support that may be required.
Unlike with personal information tests, the mother of the child must be involved in any DNA testing process. Further donors (usually additional children) can be tested for £118 each.
Analysing your genetic code using a DNA test is the most accurate way of determining whether or not a biological relationship exists between individuals.
The dadchecksilver paternity test proves with 100% accuracy if a man is not the alleged father of a child and proves that a tested man is the alleged father of a child with at least 99% certainty (if the mother is involved in the DNA testing process, we can generally improve on this figure.
For grandparentage, avuncular and sibling testing, the relationship is more distant and the results will generally indicate around a 90% chance of relatedness. If for example, the mother does not participate, then this number will reduce and can be highly variable. It can be between 50% and 90% depending upon your family’s genetic background. In a grandarentage test, if we can test both grandparents and there is no issue of paternity, we may get a probability of relatedness of up to 99%.
If you are wishing to have one of these particular DNA tests, then it is important that you understand the limitations of the technology and we would always suggest that these DNA testing data are taken in context with other evidence you may have. It is for this reason that we do not have an online ordering system for indirect paternity tests and prefer you to call, e-mail or text us, so we can arrange to discuss the case with you. We can then advise on the most appropriate DNA test which will give a conclusive and useful outcoome for you and your family.
All people providing a sample for any type of dadchecksilver DNA test must give their consent by signing the personalised consent form which will be provided with the sampling kit.
We will not process samples for any paternity test or other DNA test unless we have the signed (written) consent of each of the adult participants and if a child under 16 is involved, consent from a person with parental responsibility for the child (or children) taking part.
You should be aware that it is a serious offence, punishable by imprisonment, to personate another body for the purpose of providing a bodily sample (e.g. for a DNA test) or to proffer the wrong child for that purpose.
It is also a criminal offence to have in possession bodily material for which a DNA testing is intended, without appropriate (qualifying) consent. If the consent form has not be signed properly or appropriately, we will not proceed with the test.
If you wish to provide a sample for a dadchecksilver DNA test you must be absolutely sure that it is your sample and that you have signed the consent form which gives us permission to carry out the test.
Please note however that an individual may withdraw their consent at any time during the testing process but not after the paternity or DNA test report has been issued.
Consideration must also be given to older children e.g. 10+years and under the age of 16 years as they are likely to be able to understand the nature and possible consequences of a DNA test. We strongly recommend that the person with parental responsibility discusses the DNA test with the child and takes their views into account.
For a personal information tests, from the time we receive the consented samples back at the lab, the test will take approximately 2 or 4 working 5 working days, unless you have ordered the 2 day or 4 day turnaround paternity test.
We do not generally give written progress reports (e.g. by e-mail) until the Paternity Report is ready to be sent
Parental Responsibility (PR) means that the person concerned has all of the rights, duties, powers, responsibilities and authority that a parent of a child has by law (as defined in the Children Act 1989).
Where a child’s parents were married to each other at the time of the child’s birth, each parent will have Parental Responsibility for the child.
However, if a child’s parents are not married to each other, the mother shall automatically have Parental Responsibility over the child. Where the parents are not married to each other, the alleged father will acquire Parental Responsibility if he acts with the mother to have his name recorded on the child’s birth registration after 1st December 2003.
An unmarried alleged father will not be able to claim Parental Responsibility unless he acquires it by:
- Obtaining a court order.
- Registering a legally written agreement subject to the mother’s consent.
- Marriage to the child’s mother.
- Being granted a residence order.
- Having his name on the child’s birth certificate (for births registered after December 2003).
People other than parents may acquire Parental Responsibility by appointment as a guardian or by an order of the court.
The dadchecksilver paternity test is more conclusive if we can test all three of the child, mother and alleged father.
A test without a sample from the mother will not provide the same degree of certainty as a test with samples from both parents, but nevertheless, we would expect to report a probability of paternity in excess of 99%. Please note that tests which do not involve the mother are not acceptable for legal purposes.
No. In most cases the sample will be taken by gently rubbing a soft swab around the inside of the mouth. Full instructions are included in the “dadcheck” sample collection pack and on this website. The procedure is simple and painless and can be used on very young children and babies.
For accredited tests, we need to prove the identity of the donors, we will require the adult donor to provide ONE of the following at the sampling appointment:
This can be either:
a) A valid passport
b) Official travel documents issued to foreign nationals granted permission to remain in the UK
c) Current full UK paper or photo card driving licence
d) Current EU/EEA identity card
e) Current CIS (construction Industry certificate) CIS4 or CIS6
f) HMRC PAYE coding notice for the current tax year
g) Current Benefits Agency/DWP notification letter which is less than 5 months old
h) Current EU Residence permit
i) Current Northern Ireland voters card
j) Your current full birth certificate
k) Other photo IDs may be acceptable, but only after specific written approval from us.
Ideally, please take a copy and the original to the sampling appointment and we will verify the copy against the original. We may also wish to photograph the relevant parts of the documentation at the time of sampling. We may also photograph the donor at the time of sampling as evidence of who we have actually sampled on the day
We would also appreciate it if you could also provide ONE of the following as proof of address (unless it has already be used for an identity check):
a) Current EU/EEA identity card with address
b) Original bank statement HMRC PAYE coding notice for the current tax year
c) Current Benefits Agency/DWP notification letter which is less than 5 months old
d) Current local authority tax bill
e) Original credit card statement
f) Current Benefits Agency/DWP notification letter
g) Recent utility bill (not telecommunications)
h) Original mortgage statement
i) Solicitors correspondence
j) Local council tenancy agreement
k) HMRC correspondence showing NI number
Where applicable, these must clearly have the name and address of the donor, be less than 5 months old and not printed from internet.
For children (under 16) where the above documents may not be available, then we would like to see the original birth certificate please, and ideally the full version where there is provision for the name of the father. A valid passport (if they have one) or a valid NHS birth record will also suffice.
For accredited (legal) tests the sample collection procedures are different to personal information tests and we must take steps to correctly identify each participant at the time of sampling. We do this through an extensive network of sample collectors who will have be sent previously the kit and consent forms and will follow our identity checking procedures. They will send the samples directly back to us. You will also be photographed at the time of sampling.
Our samplers may be our own staff, entities who have joined our registered samplers scheme, registered medical practitioners or a member of a company specifically subcontracted to collect samples for us.
Additional charges may apply for sample collections and any use of next day delivery/couriers.
We operate nationwide collection service and also have arrangements in place for international identity checks and collections, most often used for immigration and surrogacy purposes or if one of the participants is based overseas.
The identity check and buccal cheek cell sampling will be conducted by either a member of Complement Genomics Ltd staff or will be undertaken by an independent third party supplier such as a registered medical practitioner, a sample collection company (an approved supplier to Complement Genomics Ltd) or one of the participants on our registered sampler scheme.
If the samples submitted for this particular DNA test were not collected by staff directly employed by Complement Genomics Ltd, the company (Complement Genomics Ltd) is not responsible for any errors or omissions which may have been made by these entities during the sampling process.
As dadchecksilver uses a home testing kit, you must be sure of the identity of the persons participating and we expect you to warrant those identities. You should be aware that it is a serious offence, punishable by imprisonment, to personate another body for the purpose of providing a bodily sample (e.g. for a DNA test) or to proffer the wrong child for that purpose.
Please note that is NOT necessary for all individuals who are giving a sample to all be present together at the same sampling venue at the same time or indeed to be in the same place for sampling. However, at the time of sampling, a child who is under sixteen MUST be accompanied by the person with Parental Responsibility, as indicated on the consent form.
On rare occasions we are unable to obtain any DNA profile, a complete DNA profile, or there may be issues with contamination/mixed profiles. The actions we will take are as follows:
1) Discoloured (e.g. due to food/nicotine) swabs or mouldy swabs (due to the long time taken to return them to us) will not be used. We will inform you of this point via e-mail and offer you a replacement kit for a charge of £12.50.
2) If we have started the laboratory work and find an issue such as no DNA on the swab, mixed profiles or adulteration, then we will inform you of this point and offer re-sampling for a charge of £44. If we do not gain enough DNA from one swab to complete the test, we will conduct the work once more, then process the second swab before taking the decision to re-sample. This can cause a delay to your expected completion date.
The original reports are sent to the person who ordered the test. The reports are in a standardised format, which complies with relevant legislation* and either excludes the alleged father or provides evidence that he is indeed the tested child’s biological parent.
If the dadchecksilver paternity test is negative (that is, the tested man is not the child’s biological alleged father), the report will say:
‘Based on the analysis of 15 independent autosomal DNA markers, Mr Hugh Izzit has been excluded as the biological alleged father of Teresa Green because greater than two of Mr Hugh Izzit’s DNA components are absent from the DNA profile of Teresa Green. In summary, Mr Hugh Izzit is not the biological alleged father of the child, Teresa Green’.
If the “dadchecksilver” paternity test is positive (that is, the tested man is likely to be the alleged father), the report will say:
‘The probability of paternity is 99.99xxx% (assuming equal prior odds) based on the analysis of 15 independent DNA markers. Hence the alleged father, Mr Hugh Izzit, cannot be excluded as the biological alleged father of Teresa Green.
The DNA results are ‘X’** thousand times more likely if Mr Hugh Izzit rather than an unrelated male is the biological alleged father of Teresa Green. In summary it is more than 99% likely that the alleged father Mr Hugh Izzit, is the biological alleged father of Teresa Green’.
We do not issue the original data (DNA profiles), since interpretation of these data is highly complex and requires a trained operative.

**The value of ‘X’ will vary between cases but will usually exceed 50,000.
For our other DNA tests, you will receive a written report from one of our geneticists and the Quality Manager which explains the test we have done and the results obtained, with any caveats and assumptions.
We correspond with the person who has ordered the DNA test (the nominated person), unless we receive their permission to enter into correspondence with those other parties involved in the paternity testing case. We will only discuss the case if we are confident we are talking to the nominated person. Please expect that we will ask you for your case number and certain other details of the case. You will have the option of specifying other instructions on the online ordering system (e.g. to whom you wish a second report to be sent, if required).
Results will be uploaded onto the secure web space we will provide for you and also dispatched by first class post.
After we have sent out your Paternity (or DNA Test) Report, we will store your DNA samples for three months and after this period, they are incinerated.
All associated paternity test paperwork and records are kept for one year and then destroyed.
dadchecksilver uses all reasonable precautions to make sure that samples received for testing cannot be mixed up. Our team of highly skilled and qualified scientists adhere to strict laboratory requirements of internationally recognised quality standard, ISO 17025 (an accreditation for testing and calibration laboratories).
We operate a tried and tested Quality Management System and included in this is the requirement for all work to be witnessed and double-checked by a second competent member of scientific staff.
Reports are always checked and counter signed by senior management (Ms Louise Allcroft MSc. and Managing Director/Quality Manager, or Dr Neil Sullivan BSc., MBA (DIC), LLM, PhD and General Manager).
The use of overseas surrogate mothers by British couples is increasingly common. Surrogacy contracts (if indeed there is one) are not enforced by UK law and are only legally binding in a small number of countries. These situations can be both highly complex and given the nature of the arrangement, emotionally highly charged.
If you are considering entering into a surrogacy contract you will find it can be a lengthy and complicated process and besides the obvious issue of the new child’s passport and nationalisation, is the need for a UK based parental order that transfers legal rights from the surrogate mother.
In the UK, the law says that the mother of a child is the woman who gives birth to that child and the father is the man she is married to at the time of conception. Therefore, if the overseas surrogate mother is married, although the prospective parents’ names should be on the child’s birth certificate (given a parental order has been agreed), the child is not necessarily recognised as automatically eligible for British nationality.
The prospective parents must apply to the Home Office for registration of the child as a British citizen before applying for a UK passport. On the other hand, if the surrogate mother is single, such an application to the Home Office is unnecessary provided that the father has provided evidence that he is genetically related to the child.
There are two types of surrogacy which present different legal implications:
The first, “traditional” surrogacy, or artificial insemination, involves insertion of sperm into the fallopian tube of the surrogate mother, who will consequently be the biological mother of the child. As a result, the surrogate mother must agree to a series of legal obligations transfer her rights as the parent of the child to the individual(s) who have opted for surrogacy.
The second, “gestational” surrogacy, more commonly known as in vitro fertilisation (IVF), involves implantation of an externally fertilised embryo where the biological parents do not involve the participation of the surrogate mother; therefore the child and the surrogate mother are biologically independent of one another. Whilst the embryo may have one, both, or neither parents as participants in the surrogacy, under UK law the mother and father of the child is the woman who gives birth to the child and the man she is married to at the time of conception.
Both of these possibilities require the use of accredited DNA paternity testing, as this is imperative to confirm the biological father of the child and, ideally, also the biological parentage of the mother if the surrogacy is gestational.
If you are involved in such an arrangement and need a DNA test, please contact us and ask to speak specifically to the company CEO Louise Allcroft, who is an expert in these matters.
We conduct many immigration associated DNA tests for both private clients and those represented by the legal profession. We liaise with Embassies and British High Commissions all over the world and will provide advice on consent and the identification of the individual to be tested. We co-ordinate sample collection. It is vital that we see any correspondence that you or your client may have had with the authorities (e.g. the Home Office), so that we can make sure you have the correct test conducted in the proper manner.
Using DNA testing technology, we can determine whether twins are fraternal or identical.
In fraternal twinning, two different eggs (ova) are fertilised by two sperm to produce two genetically distinct children, which share the same genetic relationship as siblings born at different times (full siblings). The twins could be male or female, there is no bias.
In identical twinning, a fertilised egg (an ovum) splits into two and then the two embryos develop independently. The two babies have the same original genomes (a carefully chosen phrase).
For fraternal twins we expect to see a different DNA profile from each other (but still be able to statistically calculate the relationship) and for identical twins, we expect to see the same (identical) DNA profile.
For general curiosity testing, this type of test is sufficient to resolve any question of fraternal vs identical.
