What is the policy at your hospital for discarding blood from CVP lines prior to specimen collection.

How many mL's?

Some hospitals do 5mL, some do 10mL.

Does anyone have a reference?

Thanks

Most of our central line draws come from PICC lines. We have them stop all infusions (if muliple lumen), push 10mL saline, then waste 10mL in same syringe, then draw samples. We rarely have a problem.
