Smell Outcome and Seropositivity Titre in Post-COVID-19 Patients.

Introduction: The aims of the study were to perform an olfactory assessment on patients active and post-COVID-19 using the culturally adapted Malaysian version Sniffin' Sticks identification smell test (mSS-SIT), to evaluate the patient olfactory outcome using a Malay short version of the Questionnaire of Olfactory Disorders-Negative Statements (msQOD-NS), as well as to evaluate seropositive titre (IgG) response using automated serology method.

Methods: Score for mSS-SIT was performed during the hospitalization, when patients had tested positive for SARS-CoV-2 (during COVID-19), and repeated after they had tested negative (after COVID-19). Also, each patient completed msQOD-NS and serology SARS-CoV-2 antibodies blood test was evaluated.
