qU-Sniff - the development of a short version of the Universal "Sniffin' Sticks" test.

Objectives: Extensive olfactory testing is sparsely applied in pediatric patients in clinical routine especially because of its time taking nature. Therefore a 5-item odor identification test (quick "U-Sniff", "qU-Sniff") from the 12-item "U-Sniff" test was developed.

Methods: A total of 724 normosmic children between 6 and 17 years of age, divided in four age groups, were included in this retrospective study.

Normative data for olfactory threshold and odor identification in children and adolescents.

Objective: Although previous studies have demonstrated the feasibility and validity of olfactory testing in children and adolescents using the "Sniffin' Sticks" odor threshold and "U-Sniff" odor identification test, normative data obtained in a large sample for these tests are missing. Aim of this study was therefore to obtain normative data of healthy children and adolescents for olfactory assessment.

Material And Methods: Olfactory testing was conducted using the "Sniffin' Sticks" olfactory threshold (THR) and the 12-item "U-Sniff" odor identification (ID) test.
