What our customers are saying

Frequently Asked Questions

Can a dadcheck®gold test involve only one parent?

The dadcheck®gold paternity test is conclusive (a Probability of Paternity greater than 99.999%) 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.  

Similarly, for immigration purposes, a maternity test will be less conclusive if we are unable to test the father.  

However, for various reasons, it is not always possible to gain access to both parents. For example, we have had court ordered tests where the mother has agreed to the test but then cannot be contacted by the local authority for an appointment. In such cases, and upon instruction from the ordering party, we are obliged to proceed with the child and the alleged father only. In any event, the alleged father may be excluded from parentage with 100% certainty whether the mother participates or not. 

What does dadcheck®gold actually do?

Using the latest DNA testing technology, we provide genetic tests to decipher close human biological relationships.

Most often, we work out whether or not an individual male is the biological father of a particular child. This is also called a paternity test.

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 dadcheck®gold paternity test detects the presence of regions of this unique genetic code (shown as discrete bands), which can then be used to determine if individuals are related or not. We analyse the genetic code and display the results from tested people such that we can see if every band in the child is also present in the parents. If so, there is a good chance that the child and parents are biologically related.

We can also offer tests to examine relatedness between siblings (full or half), uncles and aunts (to nieces and nephews) and grand-parentage tests (to grandchildren). These are often requested for example, in inheritance cases or when the alleged father is unavailable. We also conduct tests to support immigration applications, which tend to require both paternity and maternity tests.

How do you work with the Legal Aid Authority (LLA)?

The LAA have provided Guidance on the Remuneration of Expert Witnesses. The new rates apply to work undertaken with a case start date or representation order date on or after sent 2014. Our charges and service reflect this guidance and are within the guidelines set by the Remuneration Regulations, hence for most of the cases you have with us, prior authority for higher charges from the LAA should not be required.  

You (as Lead Body and contracting party) must discuss with us beforehand if you or any other party to the case are likely to be applying for a Legal Aid Agency certificate. This is because the LAA will apportion costs across a number of certificates (with a letter of authority for each) and we may be able to assist the Lead Body by directly issuing correctly apportioned invoices to the parties.  

Responsibility for the entire payment with respect to the case still however resides with the Lead Body as part of the Contract between Complement Genomics Ltd (dadcheck®gold) and the Lead Body (the test ordering party).  

The Remuneration Regulations makes special mention of DNA testing rates. This is on a per test basis, with a separate fee for report drafting. The LAA specifically will not pay above the rates set in the Remuneration Regulations unless there is a prior authority in place. However, for the most part this should not be necessary.  

Exceptions may arise, for example, if we need to hire the services of an interpreter to explain consent and its implications of if we have a situation where a close male relative could be the father. In the latter case the situation can become complex, and we may have to test more markers and carry out additional experimentation. We may in other cases and after experimentation, observe genetic changes which must be explained. In such cases, we will provide information and justification for the Lead Body to seek prior authority from the LAA for higher or further fees.  

The Regulations define a DNA test as “[alleged] father and child (plus mother if required)”. This rate is given at £252.00 plus VAT. Under the Regulations, the amount increases by £133.00 for each additional child tested. On occasion, there is more than one alleged father to be tested. Under the Regulations, each separate alleged father is to be considered part of a separate test. For preparation for a DNA report, the Regulations suggest a fee of £72.00 ex VAT. The hourly rate for a Geneticist (who is required to review the case), is £86.40 now ex VAT per hour. 

Court Order Testing

If your test is court ordered under s20 of the Family Law Reform Act 1969, then please provide a copy of the Court Order for our records. As we appreciate that events can move quite quickly, we may on occasion accept a written deposition from the Lead Body that the Court Order is in process. 

How accurate is the dadcheck®gold paternity test?

“Accuracy” is often confused with “certainty”. All our tests are accurate. You and your clients need to know the level of certainty, which in the case of an inclusion, we give as a probability of paternity (see Glossary). A dadcheck®gold paternity test proves that a tested man is the father of a child with greater than 99.999% certainty (if the mother is involved in the testing process). Please note that this figure can be reduced if the mother of the tested child does not participate in the test. Conversely, a dadcheck®gold paternity test proves with 100% certainty if a man is not the father of a child.
