The specialty of forensic nursing is a diverse domain within the field of nursing science. These forensic nurses receive extensive training on a wide range of forensic health-care issues. Sexual assault nurse examiners (SANEs) are a subspecialty within forensic nursing science that cares specifically for patients who were sexually assaulted, or who were suspected of being sexually assaulted. This detailed training allows SANEs to identify, collect and appropriately preserve biological evidence from patients' bodies and their clothing.
