What tubes can be centrifuged immediately?
Which of the following can be centrifuged immediately after collection.
The Gold or red-gray topped tubes contains the clot activators and polymer gel.
The complete clotting of a blood sample in a SST (serum separator tube) at room temperature usually takes 30 minutes..
What is a lavender top tube used for?
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 correct order of blood draw tubes?
The correct order of draw follows:Blood culture tube or bottle.Sodium citrate tube (eg, blue closure)Serum tubes, including those with clot activator and gels (eg, red, red-speckled, gold closures)Heparin tube with or without gel (eg, dark green, light green, speckled green closures)More items…•
What is in a purple top blood tube?
Purple blood bottles contain EDTA (ethylenediaminetetraacetic acid), which acts as a potent anticoagulant by binding to calcium in the blood.
What additive is in a royal blue tube?

What additive is in the black tube?
Black Top Tube (Vac-Tec): This tube is used for sed rates (ESR). The tube contains sodium citrate as the anticoagulant.
What is the purpose of a clot activator in a blood collection tube?
Most blood collection tubes contain an additive that either accelerates clotting of the blood (clot activator) or prevents the blood from clotting (anticoagulant).
What is Tiger top tube used for?
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. This tube is used for collecting serum.
What causes EDTA tube clots?
A common cause of clotted EDTA samples is improper mixing of sample tubes after collection. This is often an avoidable event, overcome by inverting the tube 8-10 times immediately after collection to mix the blood thoroughly with the EDTA.
How long is blood good for in a tube?
Whole blood samples should not remain at room temperature longer than 8 hours. If assays are not completed within 8 hours, samples should be stored at +2°C to +8°C no longer than 7 days. If assays are not completed within 7 days, or the sample is to be stored beyond 7 days, samples should be frozen at -15°C to -20°C.
How do you use a clot activator tube?
Collect blood to 10.0 ml/ 6.0 ml red top tubes.Invert the filled tube gently at least 5 – 6 times to mix tube clot activator with specimen.Place the tubes in the upright position in the rack and allow the blood to clot at the room temperature for 30 minutes.Serum has to be obtained from the red cap tubes.More items…
Which tubes contain anticoagulants?
Pink-top tube (EDTA) This tube contains EDTA as an anticoagulant. These tubes are preferred for blood bank tests. NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.
What happens if the proper order of draw is not followed?
In the era of lyophilized anticoagulants, order of draw is no longer important. Contamination of serum samples with K EDTA will occur routinely if order of draw is not followed. During syringe collections, contamination with K EDTA may rarely occur if order of draw is not followed.
What is the clot activator in serum tubes?
VACUETTE® Serum Clot Activator Blood Collection Tubes are red top tubes with spray-dried microscopic silica particles coating the inner walls, which activate the coagulation process. VACUETTE® Serum Clot Activator Tubes are of the highest quality and made from virtually unbreakable plastic.
