Plastic serum tubes- When frozen plasma is required, immediately place the plastic transport tubes in the freezer compartment of the refrigerator and tell your professional service agent that you have a frozen sample to collect. This mixed blood can then be centrifuged to produce a plasma that contains albumin, globulin and fibrinogen. The specified anticoagulant or preservative must be used for the ordered test. For some tests, e.g., B. chemical processes, fasting samples are often the sample of choice.
This is your basic hematology tube (which allows me to identify and count blood cells, blood type, etc..).
Which tubes do you use for blood tests?
Blood collected with an anticoagulant suitable for the test described cannot be considered suitable for other tests. Hemolysis can be caused by rough handling of a blood sample, by letting the tourniquet run too long (causing blood congestion), or by squeezing the fingertip too much during capillary collection, dilution, exposure to contaminants, extreme temperatures, or pathological conditions. To ensure specimen integrity in warm weather, follow these instructions for frozen gel packs and sample seal plasma to a plastic transport tube marked “Plasma, Sodium Heparin” or “Plasma, Lithium Heparin”.
What are the three types of blood tubes?
Only blood culture tubes, serum tubes without added glass or plastic serum tubes without clot activator may be removed from the coagulation tube. If you only need samples collected in citrate blood collection tubes for your project, you should remove a disposal tube first. It is worth noting that a citrate tube should not be the first type of tube to be filled after the venipuncture – the first few ml of the drawn blood are slightly activated. Whether you’re taking samples in-house or at a clinic, hospital, or pathology center, you need to have a good idea of what type of blood collection tube is right for you.
But what if your protocol isn’t specified, or you want to adopt a method from another system, or you simply want to make sure that you save the best sample type for future analyses that have not yet been defined? Hopefully, I can help you find your way around all these different colored tubes.
What is the EDTA tube used for?
EDTA is used for most hematological procedures to determine the complete blood count, prepare EDTA plasma, and collect whole blood and bone marrow samples. To transport swab samples or tissue, remove the cap, place the sample in the tube (break off the swab handle if necessary) and put the cap back on and pull off Plasma stored from EDTA-treated blood can also be used to measure most proteins. Genetic material can easily be used from EDTA Buffy Coats (the interface between red blood cells and plasma after centrifugation, which contains white blood cells and platelets). Tips for a good blood smear Illustration for making a peripheral blood smear (wedge smear).
Which tube should be used first when drawing blood?
Plasma is obtained from blood that has been mixed with an anticoagulant in a collection tube and is, therefore, not coagulated. In general, blood should not be drawn from an arm with a fistula or cannula without consulting the treating physician. This standard recommends that EDTA tubes be drawn first to ensure good sample quality, followed by other additive tubes and, finally, serum sample tubes. It can be assumed that airborne precautions provide a certain level of safety against infectious diseases such as tuberculosis, influenza and COVID-19.

Transfer the collected blood to the appropriate tubes as soon as possible using a blood transfer device, as a delay will cause incorrect coagulation Can lead.
