What technology does tellmeGen use? How is my DNA genotyped?

Once the DNA has been extracted from the saliva sample, it is amplified (multiplied exponentially) in order to work with it. After the amplification process, the genotyping process is carried out. To do this, we have a customised chip that collects a large number of positions of the genome. These positions have been selected, after years of research, for having solid scientific evidence. In other words, we work with DNA positions that have been validated by the scientific community and on which there are multiple publications. Some of the positions we work with have been named in more than 200 research papers.

At tellmeGen we use a customised version of the illuminaTM Global Screening Array v3.0 that is capable of interrogating over 800,000 genome positions. The customisation has over 10,000 genome positions that have been pre-selected for additional clinically relevant information.
The genetic analysis is carried out in certified laboratories that have all the corresponding regulations to offer the highest quality standards, which guarantee the accuracy and reliability of the results.
