Hello! I have a patron requesting laboratory guidelines on whether or not to have a patient pump their fist during a blood draw. I have a few articles that show that this technique raises potassium levels, but I don't have access to any phlebotomy or laboratory guidelines. I'd really like the excerpt on veinpuncture procedure from the 'Procedures for the Collection of Diagnostic Blood Specimens by Veinpuncture'- 2007, 6th ed. It is published by the Clinical and Laboratory Standards Institute. WorldCat had pretty sparse holdings on this title, so it's a slim hope that someone out there has this in their collection! THANK YOU!!!
