If you draw above the IV site you are sampling blood with a higher fraction of IV fluid, which isn't useful for clinical decisions, right? Also, if you put a tourniquet above a running IV and then put a hole in the vein, you'll get an infiltration at the IV site and a big leak at the venipuncture site. This doesn't need study, it's anatomy. Draw a picture if you have to.

Does anyone know of a study about a phlebotomy draw causing infiltrate when performed above the IV? I need evidence based info to give to my boss.
