Primary Outcomes

Description: The subject's score on using the olfactory device will be compared to the PCR results (SARS-CoV-2 negative or positive) on COVID19 outpatients. As the smell test has a variable scale (0-5) the ideal cutoff will be determined to maximize these factors: Sensitivity Specificity Accuracy

Measure: sensitivity, specificity and accuracy

Time: 24 hours

---

Secondary Outcomes

Description: Repeatability will also be examined in a test-retest score conducted within 24 hours with a second device in which the sequence of the odorants is altered.

Measure: repeatability

Time: 48 hours

---

Description: The score with the olfactory device will also be compared to subjects' response to the question "Do you have a new loss of smell or taste?" (current standard).

Measure: validation

Time: 24 hours

---

Description: We will determine if 'asymptomatic' SARS-CoV-2 positive subjects experience a partial loss of smell (hyposmia) and if so determine the fraction of subjects in which this occurs. Sensitivity, specificity and accuracy will be measured.

Measure: asymptomatic sensitivity, specificity and accuracy

Time: 24 hours
