DNA can be collected from either a blood test or a cheeck swab. Both are very accurate, although I would say that the blood test may be a bit more accurate than the cheek swab.
You can have a blood test done, but believe it or not the technology is gearing more towards the swab and the swab is as accurate. One of the reasons is the fact that sometimes people might have a blood transfusion or bone marrow transplant which can jeorpadize the test result.
No, that is not how it works.
A "buccal swab" is used for DNA tests. This means that a cotton swab, similar to a Q-tip, is rubbed against the inside of the cheek, to collect cells for evaluation. While it is just as accurate as a blood test, this procedure is painless and non-invasive, making it a much more desirable test, particularly in the case of small children. Only the child and the male in question has to be tested.
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.
Shouldn't be. A mouth swab test is testing DNA. Marijuana has nothing to do with your DNA, which cannot be changed.
They are used for many things. * Doctors such as human doctors use them for DNA samples like Saliva for example. * They use it in airports to make sure there is no explosve poison on anything. * They use it for cleaning ears. Maybe you should ask your doctor about this question.
The swab used in cheek swab DNA testing is already sterile and ready for testing when you purchase it. They are designed for single use so only use it on the person being tested. If multiple people are being tested, use the multiple swabs included in the home DNA kit. Lastly, don't drop the swab. Contamination from dropping the swab could definitely affect the accuracy of the test results.
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.
A simple swab from the babies mouth
There are no drugs that I am aware of that can change your DNA. And if your the same person that asked how accurate DNA tests are, they are very accurate. There is a very small chance that one can be wrong, but even a high paid lawyer couldn't get you out of trouble if your DNA is used. If you did something wrong (get someone nocked up maybe?) and DNA is involved, you might as well admit to it.
No there is not. Man up!
