How to test for SARS-CoV-2. 

• collect and test upper respiratory tract specimens (nasopharyngeal AND oropharyngeal swabs).  
• test lower respiratory tract specimens, if available. 
• For patients who develop a productive cough, sputum should be collected and tested for SARS-CoV-2. The induction of sputum is not recommended. 
• For patients for whom it is clinically indicated (e.g., those receiving invasive mechanical ventilation), a lower respiratory tract aspirate or bronchoalveolar lavage sample should be collected and tested as a lower respiratory tract specimen. 
• Specimens should be collected as soon as possible once a PUI is identified, regardless of the time of symptom onset.
