What the proper order of draw?

The proper order of draw for venipuncture is crucial to avoid cross-contamination of additives between tubes. The recommended sequence is: 1) Blood culture tubes, 2) Citrate tubes (light blue), 3) Serum tubes (red or gold), 4) Heparin tubes (green), 5) EDTA tubes (lavender), and 6) Glycolytic inhibitor tubes (gray). This order helps ensure accurate test results by minimizing the risk of interference from tube additives.
