What is the additive in a red top tube?

The sequence of collection of evacuated tubes in a multi-draw should be in this order:

  • Red – Non-Additive.
  • Red Gel separator tube (speckled or “tiger” top)
  • Green (heparin)
  • Green/Gray mottled Plasma Separator Tube (PST) with heparin.
  • Lavender/purple top and/or pink (EDTA)
  • Gray top (Oxalate/fluoride tube)
  • What is the additive in the yellow top tube?

    What color tube is used for serology?

    RED. Plastic – clot activators to enhance the clotting of blood, tube inversions are necessary to ensure mixing of clot activator with blood. Blood clotting time 30 minutes. For serum determinations in chemistry, serology and Immunohematology (blood banking).

    What color tube is used for troponin?

    0.5 mL. Alternative Specimen(s) Plasma collected in: Sodium heparin (green-top) tube, lithium heparin (green-top) tube, or EDTA (lavender-top) tube. Collection Instructions.

    What is the difference between the serum and plasma?

    The difference between serum and plasma is that plasma is the liquid part of blood, that is, whole blood after the removal of red blood cells, white blood cells and platelets by centrifuging. It is prevented from clotting with an anticoagulant such as sodium citrate or EDTA.

    What is a EDTA blood test for?

    EDTA blood test. An EDTA test is used to assess the function of your kidneys through a series of blood tests. EDTA refers to the name of the substance that you will receive by injection. EDTA contains a small amount of radioactive material. This allows it to act as a tracer which will show the kidney function.

    What is in a tiger top blood collection tube?

    This tube is used for preparing EDTA plasma, whole blood, and bone marrow specimens. This tube is used for collecting serum or clotted whole blood specimens. Tiger-top tube (serum separator): Tube does not contain an anticoagulant but does contain a clot activator and serum separator gel.

    What is the additive in the yellow top tube?

    What is the red top tube used for?

    Red-Top Tube: This tube is a plain VACUTAINER® containing no anticoagulant and is used for collection of serum for selected chemistry tests as well as clotted blood for immunohematology.

    What is a clot activator tube?

    A special coating on the internal wall of the tubes containing microscopic silica particles activates clotting. VACUETTE® Z Serum Sep Clot Activator tubes contain an inert separator gel on the base of the tube which, after centrifugation, forms a stable barrier between the serum and the blood clot.

    What is the order of draw for blood collection tubes?

    The draw order for specimen tubes is as follows:

  • Blood culture.
  • Red, No Gel (Plain tube, no clot additive)
  • Blue tube for coagulation (Sodium Citrate)
  • Red or Yellow-Gold SST (Plain tube w/gel and clot activator additive)
  • Green and Dark Green (Heparin, with and without gel)
  • Lavender (EDTA)
  • Pink – Blood Bank (EDTA)

    What is SST tube for blood collection?

    Serum Separator Tube (SST®) for serum determinations in chemistry and serology. Contains separator gel and should not be used for toxicology or drug testing. Inversions ensure mixing of clot activator with blood. Blood clotting time 30 minutes.

    What kind of tube is used for a CBC?

    Lavender-Top Tube – EDTA: EDTA is the anticoagulant used for most hematology procedures. Its primary use is for the CBC and individual components of the CBC. The larger (6ml) tube is used for blood bank procedures.

    What is the additive in a gray top tube?

    Oxalate and EDTA are anticoagulants which will prevents the blood from clotting, sodium fluoride is a stabilizer. The resulting supernatant fluid is PLASMA. Sodium fluoride is an anti-glycolytic only, resulting fluid is SERUM.

    Which genetic disorder causes problems with blood clotting?

    Genetic Clotting Disorders

  • Genetic Clotting Disorders.
  • Factor V(5) Leiden.
  • The Prothrombin Mutation.
  • Protein C and Protein S Deficiency.
  • Antithrombin Deficiency.
  • Elevated Homocysteine.
  • Elevated Lipoprotein(a)
  • Elevated Factor VIII (8)
  • What is the tiger top tube used for?

    Gold or red/gray tube, also known as a tiger tube that contains a clot activator. It is used to separate blood from the serum. Tubes with a red stopper are used to collect serum to test for routine donor screening or infectious disease. It contains a clot activator.

    What color tube do you draw a BMP in?

    Draw blood in a gel-barrier tube and centrifuge. If red-top tube or green-top tube is used, centrifuge within 45 minutes of draw, remove the serum or plasma, and place in a transport tube and tightly stopper the tube.
