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, collect samples in this order.

1. BLOOD CULTURES
2. BLUE
3. GOLD
4. RED (CLOT ACTIVATOR)
5. LIGHT GREEN
6. GREEN
7. PINK
8. PURPLE
9. GRAY
