This convenient system eliminates the need for syringes in many cases and reduces risky blood exposers to phlebotomist and need to transfer blood to test tubes by Lab technicians and consists of disposable needles and tubes. Evacuated tubes are made of glass or plastic and come in various sizes ranging from 2 to 10 ml. Evacuated tubes may or may not contain additives. Blood collected in tubes without additives will clot and yield serum on centrifugation. Tubes that contain additives may or may not clot, depending upon the type of additive they contain and makes testing more rapid and accurate compared to open blood collection and testing.
An anticoagulant is a substance that prevents blood from coagulating or clotting. If an insufficient amount of blood is collected in a tube with anticoagulant, the laboratory test results may be erroneous because of an incorrect blood-to-anticoagulant ratio. The blood collection vacuum tubes have been designed for a certain amount of blood to be drawn into the tube by vacuum according to the amount of pre-filled anticoagulant in the tube.
1. One hand opening leaving other hand free.
2. Easy Recapping. No risk of tube breakage or non closure as inner stopper present does not tilt as present in BI CAP stoppers.
3. Never comes Apart! One Piece.
TYPES OF BLOOD COLLECTION TUBES
Serum Blood Collection Tube
Serum Blood Collection tube aims at providing high-quality serum specimen for medical laboratories. It includes 3 kinds of tubes: no additive tube with & without clot activator with brick red cap, haemo repellant coated tube (silicon) with cherry red cap and GEL + clot activator tube with gold cap.
1: NO ADDITIVE TUBE
No Additive Tube is used in blood collection and storage for biochemistry, immunology and serology tests. It can provide non contaminated serum specimen for clinical test, while keeping the serum stable over an extended inspection period.
Colour Code: Brick Red
2: HEMO REPELLENT COATED TUBE
Silicone is used in blood collection and storage for biochemistry and immunology tests. It’s suitable for a wide range of operation, fast in coagulation, and free from both secondary separation of fibrin protein and the damage of blood corpuscle. The blood cells don’t stick to side of tube walls and result in hemolysis.
Colour Code: Cherry Red
3: GEL + BCA TUBE
GEL + BCA Tube is used for clinical biochemistry and immunology. Inside the tube there is a barrier gel present at the bottom. After centrifugation, the gel barrier that can effectively separate the serum from fibrin and cells, while preventing substance exchange between blood ‘cell and serum. As a result, it can keep biochemical characteristic and chemical components of serum stable over a long period.
Colour Code: Gold
Whole Blood Collection Tube
Whole Blood Collection tube provides high-quality blood specimen for medical laboratories. It includes 2 kinds of tubes: EDTA tube with Lavender cap (EDTA.K2/K3) and ESR tube with black cap.
1: EDTA Tube is widely used in clinical haematology as well as various kinds of blood cell test instruments. It has EDTA K3 / K2 as anticoagulant.
Colour Code: Lavender
2: ESR Tube is used in blood collection and anticoagulation for sedimentation rate test. It contains a 3.8% buffered tri-sodium citrate solution (0.129 mol/l) with the mixing ratio of 1 part citrate solution to 4 parts blood. ESR measurement is done as per the Westergren method.
Colour Code: Black
Plasma Blood Collection Tube
Plasma Blood Collection Tube provides high-quality plasma specimen for medical laboratories. It includes 3 kinds of tubes: glucose tube (Oxalate Tube) with grey cap, PTtube with blue cap and heparin tube with green cap.
1: Glucose Tubes (Oxalate Tubes) Applicable blood samples test are:
Blood sugar, sugar tolerance, red blood cell electrophoresis, Alkali-Resistant Hb Determination and sugar dissolution. Anticoagulant used is lithium lodo Acetate.
Colour Code : Grey
2: PT / PTT Tubes are designed according to the 1:9 proportions of anti-coagulants and blood samples. Because of the low toxicity of the buffer sodium citrate, blood storage can be for extended period.
Colour Code: Blue
3: Heparin Tube is used in blood collection and anti-coagulation not only for routine clinical biochemistry tests and emergency biochemistry tests but also for some test items in blood rheology. It is coated with lithium heparin (or sodium heparin on request).
Colour Code : Green
PRIORITY OF DRAWING BLOOD IN VARIOUS TUBES
For collecting multiple blood samples from a single venipuncture – the suggested order given below should be followed:
- Sterile Specimens (Blood Culture Tubes or Bottles)
- Brick Red Stopper – No Additive/BCA
- Light blue Stopper – Sodium Citrate for coagulation studies
- Green Stopper – Heparin
- Lavender Stopper – EDTA
- Gold Stopper – Contain clot activators
- Grey Stopper – Oxalate/fluoride
