A.

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 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.
  • 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 plasma in phlebotomy?

    Blood outside the body with anticoagulant is referred to as whole blood. Whole blood can still be separated into liquid and cells. This liquid is called plasma. It is the liquid portion of blood when the tube contains anticoagulant.
B.

What is in a tiger top tube?

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 is used for SST?

    SSTs are sometimes called "marble-top tubes," "target-tops," or "gold-topped tubes", referring to the stoppers which are either gold, red with a gold ring on top, or marbled red and grey.
  • 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)
C.

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 does EDTA do to plasma?

    Plasma. This is the fluid that is removed after centrifugation of anticoagulated whole blood. The exact nature of the plasma. depends on which anticoagulant is used: EDTA plasma.
  • What color tube is used for plasma?

    Differ from light blue tops because they provide a blood to anticoagulation ratio of 4 to 1. Contains Heparin (anticoagulant) combined with lithium, sodium, or ammonium ion. Primarily used for chemistry tests performed on whole blood or plasma. Why are light green tubes used for potassium determinations?
  • What color tube is used for SST?

    SSTs are sometimes called "marble-top tubes," "target-tops," or "gold-topped tubes", referring to the stoppers which are either gold, red with a gold ring on top, or marbled red and grey.
