DNA testing usually does not look at the entire genome, but at specific parts
of the DNA you are interested in. As a result, they may miss specific variants
selected for more comprehensive testing. The size of a company’s DNA sample
database will also affect the level of detail of your results, and there will
also be false positives-an analysis found that in direct-to-consumer DNA
testing, 40% of the variants and specific The disease turned out to be a false
positive.

There is also a simple explanation. Genetic science is largely a question of probability. For example, you look at a group of people with a specific disease, and then look in their DNA for similarities in the test population to the general population. The analyst will try to assess linkage and whether you share genetic markers from other populations with certain characteristics. It is not that a particular gene can "do" anything, but more probabilistic and analytical problems.
In addition, incidents that may lead to improper handling by the laboratory can be very shocking and destructive, especially in the case of paternity testing.
Looking at the world of home DNA kits, we can see many problems surrounding DNA testing in the wider society. In the criminal justice system, DNA evidence is considered to be so scientifically reliable and uncertain that it is used to release wrongly convicted people and imprison more and more people. As DNA analysis techniques become more sensitive and complex, the possibility of false positives also increases, including that someone’s DNA will appear because someone touches the same object or because different evidence is mixed in police custody.
DNA samples may also be mishandled or contaminated, and may become a problematic part of the investigation.
To some extent, the problem is not with the DNA sample itself, but with the person handling it. This can have serious consequences. Our company has DNA Test Kits on sale, welcome to contact us.
