Yellow
These blood culture tubes are filled first because they are sterile. Light blue top: These tubes, which contain sodium citrate, are next because other anticoagulants might contaminate the sample collected for coagulation studies. Red top: Glass serum tubes without clot activator, or plastic tubes with clot activator, are filled next. Green top: These tubes are drawn next because the plasma in their anticoagulated specimen is used for testing when STAT results are needed. Lavender top: These tubes are now drawn. They contain an EDTA anticoagulant that binds the calcium to prevent clotting and preserves the blood cells. Blood for this tube is drawn near the end because the EDTA additive interferes with the chemistry and coagulation specimens. Gray top: This tube is drawn last, and the blood is used to test glucose. Its additives may elevate electrolyte levels and damage cells if passed into the other tubes.
