DNA tests can’t tell the difference between dogs and people

Тесты ДНК не видят разницы между собаками и людьми

Many people use tests instead of working with doctors. and for good reason.

The popularity of home genetic tests is growing: people are interested in family history, predisposition to diseases, the best type of diet or congenital abnormalities that can be passed on to children. But usually the clients of private biotech companies do not order tests to find out whether they are human. It may not be the worst idea, because a recent experiment has shown that some tests don’t do it.

American channel NBC has conducted a comparison of several popular home DNA tests. Laughter for the sake of the journalists sent geneticists DNA black Labrador Retriever named Bailey. At that time, as most of the companies returned the sample as unreadable, one of them (Orig3n DNA) did not notice differences between man and dog. Instead, the reporter came to the 7-page report that evaluated the condition of the heart and muscle Bailey. The dog recommended to do with a personal trainer.

Occurred confusion seems funny, but it reveals a deeper and more nasty problem: many people perceive home genetic tests as a substitute for medical advice. So, instead of having to go to the profile doctor, a person can order a test and unquestioningly believe his results.

Edition Futurism writes that unscrupulous companies often credited with its tests of ability, which they can’t fulfill. For example, the BOTTOM will not tell you what wine you should drink, or who to meet. Also provided medical information difficult to interpret without the advice, and it can adversely affect a person’s attitude to their own health and life. Also there is a risk that some tests will give customers false information.

Trick dog, showed how questionable might be these tests.

“I don’t consider them particularly useful, and in some cases can even call them harmful, says Jessica Stoll, a geneticist from the University of Chicago. — The context of your medical history is very important to determine the genetic risk of diseases. We use a very specific clinical trials to determine whether there is a specific gene mutation that increases the risk for the individual. If we are going to conduct any testing, we should be based on personal and family history of the disease.”

In other words, if a person wants to use a DNA test to learn more about himself, his results should be evaluated with great care, in consultation with the professional no matter what the results were.
