Offsite Collection Instructions

• Samples must be centrifuged at >1500 x g for 10 minutes at room temperature.
• Carefully remove plasma from the cells using a plastic transfer pipette avoiding the buffy coat.
• Aliquot the removed plasma into 2 plastic tubes containing a minimum of 1000 uL of specimen in each tube.
• The plasma samples must then be frozen at -20ºC.
• Once solidly frozen they must be shipped on dry ice. Samples that have thawed in transit will be rejected.

• Note: For clients who do not have access to dry ice do not freeze the specimen. Follow the centrifugation instructions or send the whole blood sample. It now becomes vital that the specimen arrives in the lab within three hours of collection.
