Helping people avoid environmental hazards is an important part of Epidemiology. Finding innovative methods to measure and monitor health is a never-ending quest. Saliva sample collection devices offer an easy-to-use non-invasive tool that collects saliva for various health biomarker analysis. These biomarker measurements provide researchers invaluable data that can be used to monitor population health. Finding an appropriate saliva collection tool can be challenging. In response to this challenge, Elizabeth Sams invented the double-bottom test tube as a simple and low-cost collection tool that reduces processing time and cross-contamination. This test tube can be used for any wet specimen collection.
