    We draw from the line, but get an appropriate waste and our levels seem to be for the most part in the desired range.

    I am interested in other hospitals’ policies on blood draws for methotrexate levels. Do you draw from the patient’s CVC or a peripheral venipuncture/finger poke? Our physicians require a peripheral venipuncture/finger poke. The only time we draw levels from the CVC is if the family absolutely refuses to allow us to poke the child. Even then there is the stipulation that CVC draws cannot start until hour 60. Does anyone have any evidence to back up the technique used to draw levels?

    Thank you,
