Highlighted Topics Covered:
- The advantages of microscopic and presumptive screenings of physical evidence prior to expensive DNA analysis
- How these screening methods can save time, money and resources by potentially eliminating unnecessary further analysis
- The importance of proper packaging of evidence collected at the scene to ensure it is not compromised prior to analysis

Webinar Overview:
Presumptive tests for blood, seminal fluid, urine, and saliva are fast, relatively inexpensive, and can quickly eliminate a stain from further analysis if the results show the sample is not the fluid originally suspected. Likewise, microscopic analysis of hair is a nondestructive test involving minimal preparation and can confirm if hair is human in origin and determine if a particular hair is suitable for nuclear DNA analysis. Both time and money can be saved by efficiently eliminating samples from further analysis when it is deemed unnecessary by a presumptive method.

This webinar is designed for police and attorneys involved in cases with physical evidence. During this webinar, our presenters will discuss the advantages of microscopic and presumptive screenings of physical evidence, especially suspected bodily fluid stains and hair prior to advancing to more expensive DNA analysis. They will provide examples of such screenings and discuss how these screening methods can save valuable time, money and resources by eliminating samples from being forwarded onto unnecessary further analysis. They will also discuss proper packaging of evidence collected at the scene, especially stains, and why this is important to ensure that evidence is not lost or compromised prior to analysis in the laboratory.
