George, I would like to get your thoughts and references if possible about the "proper" amount of blood to discard before drawing samples for coagulation testing. In the current environment of minimizing blood waste and limiting volume of blood draws, we are reviewing our current policy. Our current SOP states to draw and discard 20 cc of blood before coagulation tube draws. We cannot find documentation to support that amount and would like to reduce that amount with some justification. If you have any insights, we would greatly appreciate it. Thanks much. Bruce King, M.D. Director of Hematology laboratory
