Saliva Participant Sampling Packs for Adults & Children 6+ Years Old
Salimetrics’ Passive Drool Participant Sampling Packs (PSPs) are customized for your study, assembled using the patented Saliva Collection Aid with analyte-validated 2mL polypropylene cryovials. These PSPs are based on best practices developed over 10,000 studies, allowing participants to collect up to 1.8 mL of saliva while reducing mess and improving compliance. Organizing your Sample Collection before you start increases the likelihood of participant compliance; obtaining, reliable high-quality samples; and creating a cleaner data set for your research study data. You don’t need to spend the time and energy sorting, labeling and organizing your individual collection devices. Each Participant Sampling Pack is pre-assembled for your protocol, making it simple for participants to collect samples correctly and your team to store them efficiently.
