Can You Cheat at A Paternity Test?

The answer is simple, Yes you can, but you will get caught! 
DNA Paternity Testing is the most accepted method of confirming a biological relationship between an alleged father and biological child. There are two types of tests you can perform. The legal or court admissible test where the collection of the samples is performed with a controlled chain-of-custody procedure with usually a doctor or registered nurse to act as a witness and verify the authenticity of the samples. Then there is the Home DNA test whereby the client purchases a DNA testing kit and is responsible for collecting their own samples.

The home test is commonly known as Peace of Mind Testing.
The legal test of course provides an almost cheat proof system. Samples are taken in the presence of a registered nurse or doctor and is accompanied by legally binding documents. However for the home DNA test, as the individuals are responsible for collecting their own samples, this gives opportunity to cheat on the test. This can be done by submitting someone else's sample which will without doubt lead to a negative result.
We cannot know if the samples provided are of the correct person (s). In fact, it is quite normal for a DNA test result to clearly state that the samples have not been verified and hence the report cannot be used in a court of law.
Only in cases where the samples submitted are of the wrong sex will our laboratory question the samples. The Amelogenin gene, a standard part of a DNA paternity test will confirm the sex of the samples. 

Also submitting the sample of an animal, example swabbing a dog will also be picked up by the laboratory as it will not be possible to conclude the test.
Once the samples are processed, our laboratory is in a position to issue a DNA profile that is unique to each individual. Whilst the result will of course be erroneous, however should a correct sample be obtained the new profile can be easily matched to the old profile to confirm if they belong to the same individual. 

If you are suspicious that an individual might cheat on the test you have the following options:

1. Perform the swabbing procedure in the presence of all parties and make sure to seal and send yourself the samples to the laboratory.


2. If it is not possible to be present at the same time or location have the samples taken in front of a neutral third party who will act as an independent witness to the collection.


3. Conduct a legal test. Clients do not normally cheat. Most clients want to find out the truth. 

However, in cases where there has been an attempt to cheat, the negative result were always challenged by the mother who will obtain the correct sample for re-testing. Mothers can also want to cheat at a paternity test. 

Mothers who know that it is likely that the man being tested is NOT the biological father will try to contaminate the child's swab with there own DNA, as they think this will provide a negative result without the laboratory noticing. Our laboratory will pick up this contamination, re-testing will be required. The truth more often than not does surface. Our process maybe easy, and yes there are clients who believe they can cheat the system. But it really is not that easy.
