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 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 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.
  • What does the light blue tube test for?

    LIGHT BLUE. Citrate is an anticoagulant which binds calcium in the blood. Since it is bound up the blood cannot clot resulting in a whole blood sample, red blood cells and PLASMA. Coagulation tubes are filled with buffered tri-sodium citrate solution.
  • What color tubes are used for which tests in phlebotomy?

    Phlebotomy Order of Draw-Tube Color and Dept.
    • Yellow. Microbiology - SPS - Blood Cultures - Invert 8-10 times.
    • Light Blue. Coagulation - NaC - Platelet Function, Routine Coagulation - Invert 3-4 times.
    • Red.
    • Gold, Tiger Top, Red/Yellow/Black.
    • Green, Light Green, Green/Gray.
    • Purple/Lavender.
    • Pink.
    • Gray.

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 is in a EDTA tube?

    Erythrocytes, leukocytes (white blood cells) and thrombocytes (platelets) are stable in EDTA anticoagulated blood for up to 24 hours. Preparation of blood smears should be done within 3 hours after blood collection. EDTA tubes are used for testing whole blood in the clinical laboratory.

What blood tube colors are for which test?

  • LAVENDER. CBC, ESR, HgbA1C, Blood Bank (must have within 24 hrs),
  • LIGHT BLUE. PT/INR, COAG FACTOR, FIBRiNOGEN, D-DIMER, APTT(must reach lab within 4 hrs or freeze)
  • What color tube used for glucose?

    GRAY. Sterile blood collection tubes for laboratory procedures requiring plasma or whole blood chemistry procedures where glycolytic inhibition of specimen is required. The anti-glycolytic properties prevent the blood cells from using the glucose in the sample.
  • What order to fill blood tubes?

    Last draw - additive tubes in this order:
    • SST (red-gray or gold top). Contains a gel separator and clot activator.
    • Sodium heparin (dark green top)
    • PST (light green top). Contains lithium heparin anticoagulant and a gel separator.
    • EDTA (lavender top)
    • ACDA or ACDB (pale yellow top).
    • Oxalate/fluoride (light gray top)
  • What color tube is used for hematology testing?

    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.
