Many people who live in suburbs of cities want to check for genetic link however are unable to do it because of non availability of facility in the area. For people who are interested in checking for genetic links it is good news that they can send their samples for checking. However it is good to go to laboratory. In laboratory there is no chance of mixing up of samples and more over samples will be taken in an appropriate manner. After the samples are given in laboratory you can get the results by mail.
