This paper presents the results of a Polish population study (n = 210) for the three STR loci vWA, D3S1358 and FGA analysed using the multiplex PCR system AmpflSTR Blue. The allele distributions were in accordance with Hardy-Weinberg expectations. The combined mean exclusion chance, mean paternity index and power of discrimination for the three loci were MEC = 0.96055, MPI = 127.1295 and PD = 0. 99986. This demonstrates that these systems are valuable tools for forensic identification and paternity testing.
