    Order of Draw

    Uploaded by

    Vincent Reyes
    This document provides information on blood tube additives and their order of draw for blood collection. It lists 10 different colored blood collection tubes, the additive in each tube to prevent clotting, and their intended use in laboratory testing. The yellow top tube contains sodium polyanetholsulfonate and is drawn first for cultures. The light blue top tube contains sodium citrate and is second for coagulation tests. The red top tube is third without additive for serum tests. Each tube's additive and intended laboratory use is described to provide guidance on proper blood collection and handling.
