Immigration DNA tests

Complement Genomics Ltd trading as dadcheck® is recognised by the Ministry of Justice as a body that may carry out parentage tests directed by the civil courts.

This means our DNA tests can be used to support applications for visas, citizenship, passport or leave to remain.

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 have been assisting families with such applications for over 15 years and are able to work both UK nationwide and worldwide using our DHL Express Worldwide courier account for fast and efficient shipments overseas.

  • Step 1

    Contact us either online or by telephone to arrange for a personalised quotation depending on your own testing requirements.

  • Step 2

    We just need to take a minimum £200 deposit at the time of ordering to cover the cost of the kit preparation and any courier fees.
    The residual balance must be paid in full before we can release the result.

  • Step 3

    Provide us with the full names and dates of birth of all test participants and the details of where each sample is to be collected.

Important information regarding sample collections:

Donors overseas
If any of the test participants reside outside of the UK, we will arrange to send a bespoke sampling kit to a medical centre of the family’s choice where the donors may go to have their samples taken.
We just require the following:
-Medical Centre name
-Medical Centre address including postal code
-Contact name for person at the clinic receiving the sampling kit
-Contact telephone and email of this person receiving the sampling kit.

Donors in the UK
We have a large network of registered sample collectors who can visit the donor in the comfort of their own home on a day and at a time that fits with them. Fees shall apply for this service and are entirely dependent on the time and travel for the sampler to reach the venue. Please provide us with the address you would like the sample collected from.

  • Step 4

    We will arrange for the shipment of sampling kits to be sent to the destinations abroad if applicable and their subsequent return to the UK. Any UK sample collection appointments will be arranged.

  • Step 5

    From the date that we receive ALL samples for processing into the laboratory we quote approximately 5-7 working days for delivery of DNA test results.

    The contracting party shall receive a written copy of the DNA test report and we can also provide the Home Office/Passport Office or family Solicitor with their own copy of the test result too.
