DNA paternity tests have proved, over many years, to be completely reliable and usable in even the most delicate judicial investigations provided that the quality standards are complied with. These are indicated in guidelines and directives issued by the national and international scientific communities.
The goal of maximum reliability, furthermore, is pursued both through dedicated training of those operating in the lab (laboratory managers, technicians, etc.), suitable structures and equipment, and the use of methodologies that have been approved by the international scientific community.
The genetic markers used must have proven to be robust, informative, transmittable according to Mendel's laws of segregation (father/mother to child) and be complemented with adequate statistics on frequency data within the population.
Finally, each laboratory must participate in periodic collaborative projects and quality controls.
When all these guarantees are provided, no doubts should remain as to the actual quality of the results obtained.
