Paternity test

The DNA analysis to verify paternity is a method, which is nowadays worldwide recognized by the legal medicine society. The analysis, also called DNA fingerprint, is based on the length of a series of DNA fragments. These fragments have a repetitive sequence (STR, short tandem repeat): an out-and-out genetic and individual identity card.


The test allows to exclude for certain a supposed father, but also to attribute the fatherhood with an high probability level (99.99%).
