[Deoxyribonucleic acid (DNA) in tests of filiation, paternity and forensic medicine]

A new precise method of personal identification with significant implications for civil and criminal paternity cases, as well as for other forensic purposes and genetic studies is presented. DNA multi-locus analysis offers a discrimination of 1 in 30 billions, constituting the most precise determination in paternity testing. If we consider that the world population is around 5 billion people, and that less than 2.5 billions are males, of the which approximately 1/3 are not adults, then we can see how the possibility of error is extremely low. It makes other paternity studies with HLA, blood groups, enzymes and proteins ineffective in paternity disputes. All courts and legal personnel should be aware of the scientific implications of this new available test in our media.
