Processing Instructions

Centrifuge tubes within 4 hours of collection. Re-mix the blood sample immediately prior to centrifugation by gently inverting the tube 8-10 times. Centrifuge the blood samples at room temp (18-25 C) in a horizontal rotor (swing-out head) for 30 minutes at 1800 RCF (Relative Centrifugal Force, x g). After centrifugation, mix the whitish layer of cells with yellowish plasma layer by inverting the unopened tube gently 5-10 times. Store the tubes on ice or at 2-8 C until ready to ship. The tubes must be kept cold (2-8 C with ice packs) and shipped with cold packs. Samples can NOT be frozen at any point. It is preferred that the blood samples reach Duke lab within 24 hours of blood draw. Please indicate the draw date/time and notify the lab before shipping.
