BD VACCU SODIUM HEPRIN GREEN

Vacutainer tubes have found wide recognition due to their functional ease. The venipuncture protocol employing a syringe requires elaborate preparations for blood sample analysis in terms of the addition of appropriate additives into the tubes that carry more risks of sampling and analytical errors.

The additives include anticoagulants like EDTA, Sodium citrate and Heparin. Some vacutainer tubes have a gel that has an intermediate density between blood cells and the serum. During centrifugation of these gel containing tubes, the blood cells sink to the bottom of the tube and are covered by a layer of the gel leaving the serum on top. When plasma containing blood platelets is required for analysis a vacutainer that does not contain gel or a clotting agent is used and centrifuged. The color code has a standard protocol and hence, finds universal application across the medical domain.
