Cora Lydell learned phlebotomy as part of her medical assistant training a few years ago. She has not worked in the laboratory environment since that time, but today her office manager asked her to work in the lab because of some staffing issues. Cora's morning is uneventful until a few hours after she starts her shift. A patient comes in with orders for coagulation studies, iron levels, a CBC, and electrolytes. Cora remembers that there is a certain order of draw that should be performed, but she cannot remember which tube should be drawn in what order. She decides to draw the tiger-top tube required for the iron studies first, then the lavender-top tube for the CBC, followed by the green-top tube for the electrolytes.Did Cora follow the correct order of draw?
