The Main Principles Of We Need Quicker Tests to Contain the Delta Variant

The sensitivity of existing FDA-authorized antigen tests differs, and hence negative diagnostic screening results must be handled depending on the situations. In the majority of scenarios, the manufacturers' guidelines for usage of antigen tests indicate that unfavorable test outcomes must be thought about "presumptive," meaning that they are initial outcomes. See FDA's In Vitro Diagnostics EUAsexternal icon.

For confirmatory testing, CDC suggests utilizing a laboratory-based NAAT that has actually been evaluated against the FDA recommendation panel for analytical level of sensitivity. See FDA's SARS-Co, V-2 Reference Panel Comparative Dataexternal icon. CDC has developed 2 general antigen screening algorithms to accommodate two broad categories of usage for antigen tests. CDC suggests following among these two antigen testing algorithms to figure out when confirmatory screening is suggested.
