Validation of the local applicability of the 'TIB' Olfactory Test Device in the era of COVID-19.

ABSTRACT:

Objective

To evaluate the validity and test-retest reliability of the novel 'TIB' Olfactory Test Device (TIB) and to determine its normative values.

Methods

The study stratified the study subjects into normosmic, hyposmic and anosmic groups according to their olfactory function. The olfactory function of the subjects was evaluated using both the traditional Chinese version of the University of Pennsylvania of Smell Identification Test (UPSIT-TC) and the TIB. The normosmic group was used to retest with the UPSIT-TC and TIB at an inter-test interval of at least 7 days. The cut-off scores of TIB among the three different groups were determined by receiver operating characteristic curve analysis.

Results
