[Paternity testing and civil affairs]

Paternity testing is based on the genetic analysis of human polymorphism markers. Recently, studies of short tandem repeats (STR) after DNA amplification have led to increased standardisation and performance of the tests and have become the reference method. Thus, the results expressed in terms of probability achieve a high level of certitude, for example the probability of paternity can exceed 99.999%. All these analyses, which are performed according to a specific quality assurance program, are a very useful tool for courts of justice.
