The tellmeGen genetic analysis is performed using a saliva sample due to several key advantages. First, saliva contains cells of different origins, which allows us to obtain a high amount of DNA with great efficiency for genotyping. Furthermore, sample collection is non-invasive, making it easier for users to perform it comfortably at home without the need to go to a hospital.
Only one saliva sample is needed to perform the complete analysis of your DNA, since all cells in the body contain complete genetic information, including cells from the oral cavity. It is important to ensure that the proper amount of saliva is collected by passing the swabs along the cheeks to obtain a sufficient sample.
In summary, saliva is the ideal sample for performing genetic analyses, including pharmacogenetic information, due to its ease of collection and because it contains all the DNA necessary for the studies.
