q-Powders: a quick test for screening retronasal olfactory disorders with tasteless powders

PURPOSE: To investigate the clinical utility of q-Powders—a retronasal identification screening test. METHODS: A total of 156 subjects (92 females, mean age: 54.5 years ± 17.3 years) completed a 3-item q-Powders retronasal identification test and a 16-items Sniffin’ Sticks orthonasal identification...

description PURPOSE: To investigate the clinical utility of q-Powders—a retronasal identification screening test. METHODS: A total of 156 subjects (92 females, mean age: 54.5 years ± 17.3 years) completed a 3-item q-Powders retronasal identification test and a 16-items Sniffin’ Sticks orthonasal identification test. We analyzed whether the q-Powders test could differentiate between subjects with normosmia and subjects with an olfactory disorder. RESULTS: Our data indicated that subjects with an olfactory disorder scored lower in the q-Powders test than subjects with normosmia. The analyses revealed q-Powders test sensitivity of 84% and a test specificity of 64.9% with a score of 2 points taken as a cutoff for olfactory disorders. CONCLUSION: The 3-item q-Powders retronasal test may be used for screening purposes in clinical research. LEVEL OF EVIDENCE: 4
