Here is the document with pre-procedural precautions and testing guidelines

Key updates:

• If the status of the current surveillance test is unknown (pending) and there is no clinical suspicion of COVID, use standard precautions based on the last negative test.

• If an urgent AGP is needed and COVID-19 clearance test results are unknown, then perform the procedure with temporary airborne isolation precautions.
  
  
• If a COVID recovered patient becomes symptomatic, treat as PUI and consult ID for testing guidance.
