SHIELD FAQ - If a person is positive on covidSHIELD should they retest? Is there a possibility it could be a mistake?


No. Retesting is not required or recommended. The covidSHIELD saliva test has a specificity of 98.9% and sensitivity of 96.8%. The test targets three highly conserved regions of the viral genome for detection. High specificity offered by three-target detection, combined with frequent testing makes the SHIELD saliva-based test extremely accurate.
