New Guidance from CDC on Discordant Test Results

​This week, the CDC released new information on testing in nursing homes through the frequently asked questions website. The new guidance addresses discordant test results (i.e. false positives and false negatives) and how nursing homes should handle these situations.  

Among other information, the CDC addresses: 

• ​Optimal frequency for testing residents and staff in response to an outbreak 
• How to determine a false positive test result on an antigen device  
• What action should be taken while waiting to confirm a false positive or negative 
• What action should be taken once a false positive is confirmed
