· Diagnostic accuracy of tests for SARS CoV-2 varies based on the type of test, target antigen, type of sample and time of testing.
· There is heterogeneity in clinical performance of rapid antigen tests; however, clinical sensitivity is lower than amplification-based assays.
· Information is limited about test strategies that combine multiple approaches (e.g. molecular and serological methods) but may add value by increasing sensitivity and specificity.
