Impact of saliva collection methods on sIgA and cortisol assays and acceptability to participants
In community-based studies of stress and immunity, saliva samples offer a non-intrusive way of gathering biological data. Cotton-based devices are widely used in cortisol research, but some may affect assay results. We compared assay reliability and perceived acceptability of three saliva collection methods: passive, cotton 'salivettes' and cellulose-cotton tip 'eyespears'. Compared to passive collection, salivettes reduced the concentration of cortisol (p = .001) and sIgA (p = .002). Eyespears...[Show more]
