Collection devices are inexpensive, easy to use, and yield testable samples. Survey responses were reported from strongly disagree to strongly agree. a The four collection devices tested are inexpensive and provide users with a range of features to choose from. Prices at time of publication are shown in US dollars. b Participants reported being self-sufficient and confident in their ability to correctly collect saliva samples (from Additional file 2: Fig. S2).
