In this exploratory study we examine the practices surrounding with respect to standardization the administration and processing of the Sexual Assault Evidence Kit (SAEK). Despite the presumed scientific objectivity of this protocol, our survey of sexual assault nurses, physicians, police, and forensic scientists found that discretionary practices pervaded the evidentiary process. We argue that there must be greater awareness of the shaping of medicolegal evidence. Given the diverse characteristics of sexual assaults and of the health care needs of sexually assaulted women, we also suggest that it may be unreasonable to apply a single standard model of a rape kit.
