DNA Paternity Testing is now the most widely used technique of confirming a biological relationship between an alleged parent and their siblings. There are essentially two types of tests you can perform. There is the 'Court Admissible' Test whereby the collection of the samples is performed via a controlled chain-of-custody process with a third party to act as a witness and verify the authenticity of the samples. Then there is also the 'At-Home' DNA test whereby a DNA testing kit will be sent to you and you will be responsible for collecting your own samples. The At-House test is also typically identified as Peace of Mind Testing.
Due to the nature of collecting the samples, the legal test of course delivers an just about cheat proof method if a neutral and qualified third party witness is employed. Then again for the residence DNA test, since the parties are responsible for collecting their own samples, this provides rise to the chance to cheat on the test. This can be performed by submitting a person else's sample which will inevitably lead to a negative result. This possibility has led some to question the reliability of the at-residence tests.
Accuracy of the DNA Paternity Test
From a scientific point of view, the accuracy of these tests is now virtually a given. When the father, mother and child participate in the paternity test, a properly accredited and skilled DNA testing laboratory will deliver a probability of paternity in excess of 99.999% thereby confirming the biological relationship, or alternatively concern a probability of paternity of %, thereby confirming with 100% accuracy the exclusion of the alleged father.
The laboratory of course can't know if the samples provided are of the right individual (s). In reality, it is really normal for a DNA test result to clearly state that the samples have not been verified and hence the report can not be utilized in a court of law.
Only in situations where the samples submitted are of the wrong sex will the laboratory question the samples, considering that by testing the Amelogenin gene (nowadays a regular component of a DNA paternity test), this will confirm the sex of the donor. Also submitting the sample of an animal (e.g. swabbing you dog) will also be picked up by the laboratory as it will not be possible to conclude the test.
In addition, as soon as the samples are processed, the laboratory will issue a DNA profile that is distinctive to the individual. Whilst the result will of course be erroneous, in the event the other party manages to obtain the correct sample, the new profile can be quickly matched to the old profile to confirm if they are comparable. Having said all this, it is still obvious that it is achievable to cheat on a residence paternity test by submitting an additional human's sample and of the very same sex.
What should really I do if I feel my partner will cheat on the DNA Test?
Hence if you are suspicious that your partner may possibly cheat on the test you have the following choices:
1. Perform the swabbing process in the presence of all parties and make sure to seal and send your self the samples to the laboratory.
two. If it is not possible to be present at the exact same time or location have the samples taken in front of a neutral third party (i.e.) (a lawyer or doctor preferable) that will act as an independent witness to the collection. If the test is not becoming completed for legal purposes then the third party witness will not want to sign any official documents for the laboratory to problem a 'Legal' result. He will just guarantee peace of mind to all the parties.
3. Order a 'Court Admissible' test and follow the chain of custody procedure needed for the collection of the samples.
4. If the other party refuses to deliver a sample under any of the above scenarios, proceed through official legal channels to 'force' the other party to participate in the test. This is of course the most costly and time consuming method and will need to be entered into as a final resort. In situations such as this, we strongly recommend obtaining legal tips.
Do Clients Frequently Cheat?
In my extensive encounter in the field of DNA testing, it is rather infrequent that a person will try to cheat on a paternity test when supplying his own sample. Most clients are bona fide clients who basically want to acquire out the truth. Also in cases where the other party suspects feasible foul play, they will take measures as per above. On the other hand, in the limited cases where there has been an attempt to cheat, the negative result had been continually challenged by (most situations) the Mother who eventually managed to obtain the right sample for re-testing.
Other examples of cheating contain Mothers who know that it is highly most likely that the man becoming tested is NOT the biological Father and they will attempt to contaminate the child's swab with there own DNA, as they feel this will present a negative result without the laboratory noticing. Then again, given that the laboratory will pick up this contamination, re-testing will be required.
In conclusion, whilst 1 may attempt to fool or cheat on a paternity test, eventually the truth alot more sometimes than not comes out either via scientific methods detecting the tampering or via the procedure of acquiring supervised re-sampling.
