There is always a way to mess up a test, most would be caused by human error. This could be due to using a swab to obtain cheek cells and thereby DNA not being sterile. If the swab is not sterile then it could have DNA on it from unknown sources all the way back to the person at the factory that made said swab. Additionally, if the person taking the sample is not careful he/she could contaminate it with their own DNA or DNA present in the environment before or after sampling. Of course the test could be messed up simply because the DNA amplification was performed incorrectly or insufficient starting material was obtained.

Can a mouth swab test be affected if smoking marijuana 3 hours before a test is carried out to determine weather a child is someones?
Shouldn't be. A mouth swab test is testing DNA. Marijuana has nothing to do with your DNA, which cannot be changed.

No. The test is done on the cheek cells because they have DNA in their nucleus. The swab can be taken from any part of the mouth or even a "punch" from the skin.

No there is not. Man up!
Can a peppermint help pass a mouth swab saliva drug test since the lines in the test turn red for negative?
This is a common misconception. When testers swab your mouth, they are actually checking your DNA through cheek cells. So no, peppermint can not help pass a drug test.
Does It matter if you have cuts in your mouth to pass a swab drug test?
No cuts in your mouth will not affect swabbing that mouth for a DNA test, because they do it to get your saliva. So either way the saliva can get taken. Hope this helps you. Good luck!
Is the DNA cotton swab test accurate?
Not always.
Does the FBI test for illegal drug use with its DNA database swab test?
of course not. That is just some crazy conspiracy theory. They cannot test for drugs in the saliva in your mouth unless you had just taken the drug and the residue is in your mouth, and it is an ineffective method.
Can a moms dna over power a swab test?
No, that is not how it works.
What can affect a cheek swab paternity test?
Anything that can destroy cells. The cheek swab collects cells, which are then used to extract DNA for testing. To my knowledge, there is nothing short of cellular destruction that can impede the collecting of a sample for a DNA test, since the test is actually conducted on the DNA extracted from INSIDE the cell, not just the swab.
How can one determine who her baby's father is?
With DNA tests of the possible fathers and of the baby. Today it can be done with a simple swab test on the inside of the mouth. If he refuses you can get a court order.
How does a blood test connect two siblings with a the same mother?
A DNA sample is extracted from a swab taken from the mouth of each sibling. The resultant DNA 'fingerprints' are compared to a sample fingerprint of the mother's DNA. They should contain half the DNA fingerprint of the birth mother.
