A casework study comparing success rates and expectations of detecting male DNA using two different Y-STR multiplexes on vaginal swabs in sexual assault investigations where no semen has been detected

17% of the cases in this study generated Y-STR profiles suitable for subjective or statistical evaluation following analysis with Yfiler® compared with 34% of the cases analysed with Powerplex® Y23, demonstrating the value of using more recently developed Y-STR multiplexes compared with older kits.
