Heparin
The proper order of draw for a syringe method is: Blood culture tubes Coagulation tubes Serum tubes Heparin tubes EDTA tubes Glycolysis inhibitor tubes
Order of draw is Yellow addictive is SPS blood culture invert 8-10 times. Light blue addictive is Sodium Citrate invert 3-4 times. Red addictive No clotting invert 5-8 times. Serum addictive Silica invert 5-8 times. Green addictive heparin invert 8-10 times. Lavender addictive EDTA invert 8-10 times. Last is Gray addictive Potassium invert 8-10 times

The order of draw for blood collection tubes typically starts with tubes that do not contain additives, such as the red top tube for serum samples. This is followed by tubes with specific additives for various tests, such as anticoagulants like EDTA or citrate for plasma samples. The specific order may vary depending on the facility's protocol.

The correct order of draw according to the Clinical and Laboratory Standards Institute (CLSI) is blood culture tubes first, followed by coagulation tubes, then serum tubes, and finally tubes containing additives such as heparin or EDTA. This sequence helps minimize the risk of sample contamination and ensures accurate test results.
Syringe
The lavender top blood tube should be inverted gently and slowly 8-10 times to ensure proper mixing of the blood with the anticoagulant. Over-inverting may cause hemolysis.

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.
