What information does a DNA test provide?2 min read
To simplify it, DNA contains all the information that defines a person’s characteristics. The height of the body, the way of speaking and even possible diseases are comprised in the DNA. With a DNA test, laboratories can find out whether two people are genetically connected and at what level, i.e. whether they are parent and child, grandparent and grandchild, siblings, among others. Thanks to technological advances, laboratories have made it possible for people to carry out such tests without leaving their homes. For example, a man can buy a fertility test, have it delivered to his home, take the test according to the instructions and get the results in a matter of minutes. It is no longer necessary to travel to a laboratory to obtain this type of information. Moreover, it is not the only type of test you can do remotely.
How do the tests you can buy online work?
Before doing any kind of DNA test, you should check the website of the laboratory you have chosen to see if they have the possibility of sending sample kits to your home. Not all laboratories offer this advantage. Once you have found a professional online laboratory, the next step is to understand how each kit works. In order to be able to analyse the DNA, the lab needs to receive the samples. Unlike the fertility test mentioned above, DNA requires professional equipment for analysis. What the lab does is send you a kit with everything you need to take the samples at home. Then you just send the kit back to the lab and wait for the results.
Is it legal to do a DNA test?
Because DNA contains each person’s information, laws prohibit its unauthorised use. However, if a person voluntarily chooses to take a test in which his or her DNA must be used, the law allows it. On the other hand, laboratories must ensure that neither the samples nor the personal information of their clients is leaked and becomes public. To avoid this, it is important that you choose a professional laboratory with a proven track record. You should also make sure that the laboratory has all the permits required by the legislation of the country in which it is located. The results of a DNA test can also be used in a legal case, but for this particular situation, the samples can only be taken by authorised personnel who will take custody of them until they reach the laboratory.
