Paternity test with two dads

Paternity test with two dads

AlphaBiolabs’ Peace of Mind paternity test can be performed with two dads and one child. The standard testing kit provides enough swabs to test one child, one alleged father and the mother (if available). However, extra swabs to paternity test another alleged father can be requested when ordering the kit.

The testing kit can be ordered direct from our website and sent to any convenient address. It includes full instructions on how to collect the DNA samples. You simply need to rub the mouth swabs provided on the inside of your cheek to collect some cells. These collected buccal (inner cheek) cells are then returned to our UK-based laboratory using the self-addressed envelope contained in the paternity testing kit.

The Peace of Mind paternity test is priced at just £99 for next day results. Same day results can also be made available for an extra £70.

How do paternity tests with two dads work?

When we receive your samples back at our laboratory, DNA profiles are produced. Our scientists examine specific DNA markers present in repeat sections of DNA from each sample. The child’s DNA is analysed to identify which half is inherited from the father and which half is from the mother. If one of the men undergoing the DNA testing is indeed the biological father, both he and the child will share identical sections of DNA at each marker. If the tested man is not the biological father there will be differences in the DNA.

AlphaBiolabs is one of just a few laboratories accredited to test up to 42 DNA markers in standard tests (most relationship tests examine only 16 or 21). We also test all our exclusion results twice so you can be confident of getting accurate results.

We also offer a prenatal paternity test, which can be used to non-invasively determine paternity of a baby before birth. This innovative test is completely safe to the mother and unborn child, and can be performed as early as 7 weeks into pregnancy. The mother needs to supply a blood sample and the alleged fathers again use a mouth swab to collect their DNA.

The test costs £795 for confidential results in 7 working days. An express service can also be bought, which provides results in 4 working days for an extra £200.
