Whole genome sequencing is one of the more detailed approaches to studying human DNA because it can examine a very large portion of the genetic sequence. A whole genome sequencing service may be considered for different research or healthcare purposes depending on the situation and the type of testing available. Unlike tests that focus on a small group of genes, whole genome sequencing can examine a much broader range of genetic information. That sounds impressive, but more information does not always mean that every result will have a clear medical meaning. Interpretation is an important part of the process. People comparing whole genome sequencing services should look at what is included, how results are interpreted, what type of professional review is available, and how genetic data is handled. It is also worth asking whether the service focuses on clinical testing, research, wellness information, or another purpose. Genetic information can be sensitive, so privacy should also be considered. What would you want to know before choosing a whole genome sequencing service?
