A Novel Application-Based Test for Rapid Screening of Olfactory Dysfunction

Can a 5-item, mobile application–based olfactory test reliably screen for olfactory dysfunction (OD)?In this diagnostic study including 484 adult participants, a novel, self-administered olfactory screening tool achieved an area under the curve of 0.87, a sensitivity of 74%, and a specificity of 86% for detecting OD.These findings suggest that the novel test has potential as a rapid and reliable OD screening tool in patient care.
