- When obtaining specimens from indwelling lines that may contain heparin, the line should be flushed with 5mL of saline; and the first 5mL of blood or 6-times the line volume (dead space volume of the catheter) be drawn off and discarded before the coagulation tube is filled.

- For those samples collected from a normal saline lock (capped off venous port) twice the dead space volume of the catheter and extension set should be discard.
