    Help with ER blood draw order and tube color!

    Regarding the order of lab draw, I found some relevant info: http://www.labtestsonline.org/understanding/analytes/potassium/test.html There can possibly be an incorrect result of elevated potassium by "drawing a tube that has an anticoagulant containing potassium prior to a non-anticoagulated tube. This results in specimen contamination of the non-anticoagulated tube with potassium."
