Plasma must be separated from cells immediately after venipuncture and transferred to light-protected amber plastic tube. Separated plasma must be placed on dry ice for shipment within 4 hours of separation. To avoid delays in turnaround time when requesting multiple tests on frozen samples, PLEASE SUBMIT SEPARATE FROZEN SPECIMENS FOR EACH TEST REQUESTED.
