Before collecting and handling specimens for Coronavirus testing, determine whether the patient meets the current definition for a “patient under investigation”.
Since the pathogenic potential and transmission dynamics of Coronavirus is not fully understood we recommend collecting multiple specimens from different sites at different times after symptom onset, if possible.
As given by CDC:
Points to consider when determining which specimen types to collect from a patient under investigation for Coronavirus infection include:
- The number of days between specimen collection and symptom onset
- Symptoms at the time of specimen collection
Additional points to consider:
- Maintain proper infection control when collecting specimens
- Use approved collection methods and equipment when collecting specimens
- Handle, store, and ship specimens following appropriate protocols
- Clearly mention the travel history and possible contact history if available.
