Our supervisor came to the office the other day and said we can no longer draw any labs from any IV start that we do. She said this was a lab directive because it hemolyzes the blood. We were latter told that it is because the draw hurts the veins. Lab nor anyother department knows about this. We are the IV Team and we were never consulted about this (our supervisor has little understanding of IVs). We understand the possiblitiy of problems with vaccuntainers and aggressive withdrawl from the catheter on the vein and hemolyzation. Has anyone else heard anything new?? Thanks in advance.
