All subjects received both the Self-Administered WETT and the new B-WETT which are comprised of disposable plastic strips containing sucrose, citric acid, sodium chloride, caffeine, and monosodium glutamate tastants to evaluate taste function. The healthy volunteers were re-tested with the WETT and B-WETT after an inter-test interval of at least 7 days to measure retest reliability.  \nResults: The sum scores of five tastants of the first test were 25.7 for males and 29.5 for females in WETT, and 12.4 for males and 15.2 for females in B-WETT. There were significant differences in the sum scores between males and females whether in WETT or B-WETT. The sum scores strongly correlated between WETT and B-WETT, whether in healthy volunteers or in patients with gustatory dysfunction (r >0 .7) . There was also a strong correlation between the first and second tests of B-WETT for the sum scores. Conclusion: This study shows that B-WETT is a valid and reliable taste test, and is convenient for use in the era of COVID-19 to evaluate the taste function of patients.  \nKeywords: Brief Self-Administered Waterless Empirical Taste Test; COVID-19; Taste test; Validity; Waterless Empirical Taste Test  \n1. INTRODUCTION  \nTaste is an often overlooked sense.1 According to the National Health and Nutrition Examination Survey 2013–2014, approximately 26.3 million subjects aged 40 years and older in the US population experienced taste problems.2 These problems may cause anxiety, depression, or nutritional deficiencies in these patients.1 To provide adequate management for patients with taste dysfunction, a comprehensive assessment of a person’s taste function is necessary to make a correct diagnosis.3 Traditionally, taste function has been evaluated using solution-based taste tests.4,5 However, there are some drawbacks to these types of tests as they are usually time-consuming and commercially unavailable, and require assistance to be administered.6  \nSeveral taste tests using tablets, edible wafers, or taste strips have been developed to overcome the shortcomings of solution-based  \n* Address correspondence.
