How much blood do you waste when drawing from a central line?

A minimum discard sample of 5 ml is required when drawing blood samples from central venous lines due to longer lumen volume. Peripheral IVs should not be used for blood sampling due to the high risk for hemolysis. If IVs cannot be temporarily stopped, the patient should have an arterial line for lab sampling.
