The number of poor or altered specimens received by the USACIL (criminal investigation laboratory) each month reflect the need for changes in the Sexual Assault Determination Kit. The samples received are often moldy, making it difficult if not impossible to determine the secretor status. This occurs when the saliva sample is not properly dried. Also, condensation can develop when the saliva sample is placed in a plastic bag. Further, the kit does not contain a standard saliva sample to provide the forensic chemist something with which to compare the saliva sample. Also, the vaginal and cervical swabs are not being thoroughly dried and are often received moldy. These swabs are not specifically addressed in the kit's notes and instructions to the physician. Vaginal pool swabs are often obtained with too much saline on them, making it difficult for the forensic chemist to break down the specimen. Vaginal valences or washes are not mentioned in the instructions, although in some cases they are helpful to the forensic chemist. Hairs present another problem, as there are never enough sent to the lab. The physician directions on collecting hairs need revising. Instructions for obtaining fingernail scrappings also require revisions. Moreover, physicians are placing fixatives on vaginal, cervical, and spermatozoa motility smears as directed by kit instructions. This hinders the chemists in providing an accurate opinion about the smears. Improvement in the investigation process requires that investigators, physicians, and the laboratory have a common understanding of the nature and quality of evidence required and how this evidence is to be collected. Proper training should ensure that these procedures are implemented.
