What does a Rapid serum Tube contain?
BD Vacutainer® Rapid Serum Tubes (RST) contain thrombin-based clot activator and polymer gel for serum separation. Samples processed in these tubes are used for serum determinations in chemistry.
What tube is used to collect a serum specimen?
Serum is usually collected in mottled red/gray, gold, or cherry red-top tubes, and red-top tubes are occasionally used. Plasma is obtained from blood that has been mixed with an anticoagulant in the collection tube and has, therefore, not clotted.
What color top is serum separator tube?
PHLEBOTOMY SERVICES
| STOPPER COLOR | CONTENTS | VOL. |
|---|---|---|
| Red | No additive | 7.0 mL |
| Light Blue | 3.2% Sodium Citrate | 4.5 mL |
| Gold Top (Serum Separator, “SST”) | Contains separating gel and clot activator | 6.0 mL |
| Light Blue – Yellow Label on Tube | Thrombin | 2.0 mL |
What is the clot activator in serum tubes?
Serum (clot activator) tubes (color dependent on brand: BD is commonly gold but also red, Greiner is red). These tubes have silica particles, which activate clotting. Some also have a gel to separate the serum. Although the silica-coated tubes clot within about 30 minutes, the orange tubes clot within 5 minutes.
What does SST tube test for?
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 is the difference between serum and plasma?
Serum and plasma both come from the liquid portion of the blood that remains once the cells are removed, but that’s where the similarities end. Serum is the liquid that remains after the blood has clotted. Plasma is the liquid that remains when clotting is prevented with the addition of an anticoagulant.
How does serum separator tube work?
Serum separator collection tubes contain a gel that separates the clot from the serum in whole blood specimens. During centrifugation, the gel moves to create a barrier between cells and serum, providing access to the serum for various chemistry, serology and other procedures.
What is specimen type serum?
Serum. Serum is the liquid portion of the blood obtained after a serum sample tube has been allowed to clot and is centrifuged. The serum tube may or may not contain a separator gel. Use a tube with no anticoagulant (i.e. red-top tube, marbled-top tube or SST®).
What are citrate tubes used for?
The “citrate tube” is for collecting blood for performing coagulation studies. It contains 3.2% sodium citrate as its anticoagulant. [3] Mixing the blood inside the tube a few times is also recommended to form the plasma. There is no anticoagulant or additive inside the tube.
Why BDBD Vacutainer tubes?
BD Vacutainer plastic tubes BD Vacutainer plastic tubes offer a safe method of blood collection and reduce the potential for tube breakage and specimen spillage, thereby reducing the potential for exposure to bloodborne pathogens.
What types of blood collection tubes does BDBD offer?
BD provides a full offering of Vacutainer ® blood collection tubes in both glass and plastic. This table provides ordering information for EDTA tubes, in plastic and glass. This table provides ordering information for rapid serum, glucose, herparin, serum, BD SST ™ and BD PST ™ tubes.
What is the composition of the rapid serum tubes?
BD Vacutainer® Rapid Serum Tubes (RST) contain thrombin-based clot activator and polymer gel for serum separation.
