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.
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.
- 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.
- 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).
- Green top tube with sodium or lithium heparin: used for plasma or whole blood determinations. EDTA tubes: includes Lavender top, Pink top (used for blood bank testing), Tan top (used for lead testing), and Royal Blue top with EDTA (used for trace metal whole blood or plasma determinations).
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.
- 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.
- 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.
- Purple or lavender: K2 EDTA. This is a strong anticoagulant and these tubes are usually used for complete blood counts (CBC). Lavender top tubes are generally used when whole blood is needed for analysis. Citrate is a reversible anticoagulant, and these tubes are used for coagulation assays.
- TUBE COLOR. TESTS.
- 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)
- RED/GOLD CENTER (SST)
- RED/BLACK CENTER.
- LIGHT GREEN.
- ROYAL BLUE.
- 0.5 mL.
Plasma collected in: Sodium heparin (green-top) tube, lithium heparin (green-top) tube, or EDTA (lavender-top) tube.
- 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.
- 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)
