Require serum- Since additives are not interchangeable, it is necessary to consult the sample requirements section of the individual test descriptions to determine the appropriate collection requirements for the ordered test. Blood collected with an anticoagulant suitable for the test described cannot be considered suitable for other tests. Attempts to push more blood into the tube by applying pressure, such as collecting with a syringe, resulting in red blood cell damage (hemolysis). A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper that creates a vacuum seal within the tube and makes it easier to draw a predetermined volume of fluid.
What materials are needed for blood sampling?
It’s over quickly and requires very little preparation. Therefore, anxiety and anxiety are reduced in patients, especially children and nervous adults. There are also risks associated with storage, transportation, and potential loss or contamination of blood samples after collection. Blood collection or blood collection usually involves taking blood and comes in many different forms. The sample is taken from a superficial vein in the upper extremity, generally the middle cubital vein. This vein is close to the skin and doesn’t have many large nerves nearby.
When blood flow stops, remove the tube by holding the hub firmly and pulling the tube away from the needle.
What is the Vacutainer system of blood collection?
These tubes are used for coagulation tests and must be completely filled to ensure the correct ratio of blood to anticoagulant. The needle actually has a second, smaller needle, and when a Vacutainer test tube is pushed down into the holder, its rubber cap is pierced. When the tube is centrifuged, the blood cells sink to the bottom of the tube and are covered by a layer of gel, and the plasma (or serum) stays on top. Hold the hub firmly and insert the first vacuum tube into the large end of the hub that penetrates the plug in the correct order of pulling.
Which Vacutainer would you use for a blood test that requires serum?
Most of these collection tubes, which contain an additive, either specifically prevent blood clotting, also known as an anticoagulant, or accelerate blood clotting. The collection process required phlebotomists to use a needle to puncture the vein and then maneuver the blood into the glass tube. For some routine biochemical laboratory tests, the results may be changed by choosing the blood collection tube and storage conditions (3,5, The latest trends in vacutainer development involve a stronger tubing material made from a plastic and polyethylene formulation.
This collection tube is generally used for glucose tolerance testing as well as for blood alcohol and lactic acid testing.
