III. Storage Practices for Physical Evidence
A. Physiological fluids (i.e., blood, saliva, semen, etc.) must be preserved using the following methods.
1. Refrigerate liquid blood samples.
2. Air dry at room temperature and then freeze items such as:
a. Saliva samples,
b. Stained clothing/fabrics,
c. Stained swabs,
d. Stained gauze cuttings, and
e. Dried blood or semen crusts.
3. Without air-drying, place used condoms in a plastic container and then freeze ASAP.
4. Stained hard objects such as guns, rocks, metals, etc. should not be frozen or refrigerated. Subse-quent condensation may dilute or otherwise impact physiological fluid evidence. Store objects at room temperature and notify the lab ASAP.
5. If other types or forms of physiological fluid evidence are encountered, call the WSP Crime Lab Biochemistry Unit Forensic Scientist at 206-262-6020 for acceptable methods of preservation.
