Though we collect most hemostasis specimens using evacuated tubes, we often resort to syringes when patient veins are small or fragile. Many of us specify syringe collection for global whole blood assays and platelet function tests.

On June 28, hemostasis researcher Dave McGlasson asked George, "what temperatures do most of us use to store centrifuged, platelet-poor plasma when testing is delayed?" We assumed most of us use –70ºC freezers, but it may be that many lab practitioners use alternative specimen storage protocols.

Here are the 6-7-17 results of our latest Quick Question survey. The topic of specimen hemolysis came up in a lengthy December 6, 2016 entry featuring comments from Dennis Ernst, Center for Phlebotomy Education.

Here is a question forwarded by friend and colleague Dennis Ernst, Center for Phlebotomy Education. When we must draw from the arm with fluids infusing, our policy has always been that the RN must pause the IV. If the IV is in the other arm, we do not ask the nurses to pause the infusion no matter what is being infused or what is being drawn. This past week, we had a nurse get upset with us because the phlebotomist did not ask her to stop the heparin infusing so an anti-factor Xa could be drawn from the opposite arm. Should our policy be changed?
