Order of Draw

Note: When using a winged collection set for venipuncture and a blue top is the first tube to be drawn, a discard tube should be drawn first (do not completely fill). The discard tube should be a non-additive (plain red) or an extra blue top.

To ensure that the chance of carry-over of anticoagulants/additives has a minimal effect on sample integrity.
