Can you do a paternity test without a child knowing? With AlphaBiolabs you can.

When you order one of our home Peace of Mind DNA tests, we send a testing kit out to an address of your choice. Collecting a DNA sample is a simple process. A mouth swab needs to be rubbed on the inside of the donor’s cheek. If the test is to determine paternity, a DNA sample is needed from the alleged father, the child, and the mother if available.

Using a mouth swab to collect DNA is not invasive. However, it could lead to awkward questions from older children. This would especially be the case in paternity disputes.

Thankfully, you can perform a paternity test without a child knowing by choosing AlphaBiolabs’ toothbrush and nail DNA testing services. Consent is needed for anyone taking part in a DNA test. However, an adult with parental responsibility can provide consent for children under 16 years of age. This means that instead of rubbing a mouth swab on the inside of the child’s cheek, you can simply send in their used toothbrush. Alternatively, you could send us their collected nail clippings. These discreet methods of DNA sampling mean the child doesn’t need to know about the paternity test.

As with AlphaBiolabs’ paternity and prenatal paternity tests, if our scientists can get a DNA profile from the toothbrush and nail DNAtests, they will examine up to 42 markers to determine which half of the child’s DNA is inherited from the mother and which half is from the father. If the man is indeed the biological father of the child, both will share identical sections of DNA at each marker. If the man is not the biological father, there will be differences in the DNA of both the man and child.
