Evacuated Blood Tubes
Evacuated Blood Tubes
Capped sterile tubes with an internal vacuum that are commonly used to collect venous blood specimens; products are available in various materials, with various stopper types, and anticoagulants.
Evacuated blood tubes are sealed, single-use, capped tubes used with suitable collection needles and tubing for the safe and sterile collection of blood samples from human or animal subjects. They are partially evacuated to facilitate blood draw when the collection needle punctures the cap. The closure caps may be color-coded, depending on the tube additives or specific purpose.
Evacuated blood tubes are typically made of plastics such as polypropylene or PET to minimize the risk of breakage, although glass evacuated blood tubes are also available. Available as plain, empty tubes, many are pre-loaded with additives or preservatives that stabilize the blood sample or contain gel separators to facilitate the separation of blood cells from serum or plasma.
Evacuated blood tubes are widely employed in hospital blood collection (phlebotomy) departments and in other clinical, veterinary, and research settings. Once filled, evacuated blood tubes can be securely stored or transported for subsequent analysis of serum, plasma, or whole blood by clinical chemistry, blood counts, or other tests.
Types of Evacuated Blood Collection Tubes
• Red top: plain tubes without additives; for serum samples
• Purple top: contain EDTA anticoagulant; for clinical hematology procedures
• Green top: contain heparin; for plasma samples
• Gray top: with added fluoride or oxalate; for glucose determinations
• Blue top: with sodium citrate; for coagulation testing
• Other additives and colored closures
BD Vacutainer™ Hemogard™ Closure Plastic K2-Edta Tube
Used to obtain a whole blood or EDTA plasma sample. Vacutainer™ Hemogard™ Closure Plastic K2-Edta Tube contains K2EDTA which is a liquid solution that is spray coated onto the interior surface of the BD Vacutainer Plus Tubes.
BD Vacutainer™ EST™ Blood Collection Tubes
May be used as a discard tube, to remove the dead space from the tubing of blood collection sets. BD Vacutainer™ EST™ Blood Collection Tubes are plastic tubes with no additive in them, with a clear label and pearlescent white Hemogard™ closure.
BD Vacutainer™ Citrate Tube
Contains buffered trisodium citrate solution. BD™ Vacutainer™ Citrate Tube contains an anticoagulant additive equivalent to 3.2% trisodium citrate for coagulation investigations. It is also suitable for carrying out special test procedures, such as the platelet function test PFA-100.
BD Vacutainer™ Heparin Plasma Tubes
Achieves optimum anticoagulation by the use of pharmaceutical-grade Heparin. BD Vacutainer™ Heparin Plasma Tubes are made of durable PET plastic with a green Hemogard™ closure. Tubes in 2, 4, 6 and 10mL sizes are available with either Sodium heparin or Lithium heparin as an additive.
