| Gray additive? | Potassium oxalate and sodium fluoride, or lithium iodacetate and heparin |
| Black additive? | Buffered sodium citrate |

| Pink additive? | K3 EDTA |
| Which tubes must be completely filled with blood? | Light Blue and Black tubes. |
| When using a butterfly needle to collect a coagulation tube first, what special procedure must you follow? Why? | You must draw some blood into a "discard" tube first. If you do not, air from the tubing will cause the coagulation tube to fill incompletely. |
