There is a need for the hospital laboratory to determine if processing of the samples is time-sensitive and critical to patient safety as we would prefer if the patient is confirmed negative or has recovered from the Covid-19 infection before the samples are sent to us. 

However if the case is urgent and blood has been approved for the patient, we would not hesitate to accept and process the sample. Do also inform us prior to sending the sample.

As for the requirements of packaging, you can follow the MOH guidelines (MOH Circular 17/2020) on the handling of these samples.
