Sniffin' sticks smell identification test: exploring measurement properties in an adult Brazilian healthcare professionals sample.

ABSTRACT:

Introduction

Olfactory evaluation has gained significant attention in both neurological and otorhinolaryngological assessments, particularly following the COVID-19 pandemic where SARS-CoV-2 infection emerged as a frequent cause of chemosensory dysfunction.
