Our peace of mind home DNA tests can be easily bought online and posted direct to any address. The DNA testing kits can also be bought at High Street stores in East Canton, Albany Road, Newport Road and Cowbridge Road.

We offer paternity and maternity testing from just £99 with next day results. Sibling, twin, grandparent, aunt and uncle, Y chromosome and single profile tests are also available. The testing kits include full instructions and simply involve rubbing a mouth swab on your inside cheek to collect buccal cells.

As soon as we receive your DNA samples back at our lab, the testing process begins. You can get your results the same day or next day depending on which timeframe you choose.

All types of home DNA testing in Cardiff

As well as the standard home DNA tests, we also offer a prenatal DNA test, toothbrush testing and nail DNA testing. Legal DNA testing and immigration DNA testing is also available.

Prenatal paternity tests can be used to non-invasively determine paternity of a baby before birth. This innovative test can be performed as early as 5 weeks after conception. The test is completely safe to the mother and unborn child. The mother needs to supply a blood sample and the alleged father uses a mouth swab to collect his DNA. The testing kit can be sent to an address of your choice, and there are three options for providing your blood sample. You can contact a medical professional to have the blood sample taken, we can send out one of our trained sample collectors to an address of your choice, or you can use our Walk in Centre in Cardiff town centre.

Priced at £875, results take up to 7 days but can be fast-tracked with our express 4-day service for an extra £200.  

Toothbrushes and nail clippings have also been proven to be a good source of DNA and offer an alternative method of testing. These DNA viability tests don’t require a testing kit to be mailed out, simply send in a used toothbrush or your nail clippings in a clean envelope. An advantage is that samples can be collected in an unobtrusive manner. For example, using a mouth swab on older children could lead to awkward questions in the case of paternity disputes. If our in-house scientists can get a DNA profile from the nail clippings or toothbrush, then a standard DNA test can be performed in the usual way.

All DNA relationship testing is performed at our in-house laboratory in Warrington where we analyse up to 35 DNA markers.
