How can a DNA mouth swab test be messed up?
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.
