What is the gel in SST tube?
SST tubes contain spray-coated silica and a polymer gel for serum separation. They use for serum determinations in chemistry, serology, immunology and HIV tests [1]. Serum separator gel that is located at end of the tube plays the role of a stable chemical and physical barrier between serum and blood clot [7].
How does thixotropic gel work?
thixotropy, reversible behaviour of certain gels that liquefy when they are shaken, stirred, or otherwise disturbed and reset after being allowed to stand. Thixotropy occurs in paint, such as lithopone in oil, which flows freely when stirred and reverts to a gel-like state on standing.
What is thixotropic separator gel?
A thixotropic gel-like composition comprising liquid polybutadiene and an inorganic inert filler dispersed therein is adapted for use as a sealing barrier between separated phases of differing densities of a fluid in which said composition has at rest a density intermediate said differing densities, said gel-like …
What is the additive in a gold top blood tube?
Blood Collection Tubes
| Tube cap color | Additive |
|---|---|
| Red or gold (mottled or “tiger” top used with some tubes) | Serum tube with or without clot activator or gel |
| Green | Sodium or lithium heparin with or without gel |
| Lavender or pink | Potassium EDTA |
| Gray | Sodium fluoride, and sodium or potassium oxalate |
What is the use of gel tube?
The main benefits of separator gel tubes are an easy use, short processing time through clot activation, higher yield in the isolation of serum or plasma, reduced aerosolization of hazardous substances and a single centrifugation step [17].
What does the gel do in a serum separator tube?
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 the purpose of thixotropic gel?
Thixotropic gel forms a barrier between blood cells and serum or plasma, thus preventing contamination and allowing easy separation. Glycolysis is a cellular reaction used to harvest energy from glucose. Blood specimens used for analysis are whole blood, serum, and plasma.
Which tube contains thixotropic gel?
PHLEBOTOMY: TUBES, TEST AND ORDER OF DRAW
| Question | Answer |
|---|---|
| tube containing a gel separator and silica to activate clotting. | SERUM SEPARATOR TUBE (SST) |
| an electrolyte STAT test is usually collected in a: | LITHIUM HEPARIN TUBE |
| color top that contains SPS | GRAY |
| color top that contains THIXOTROPIC GEL | GOLD OR MOTTLED RED AND GREY |
Why is there gel in blood tubes?
Blood sample tubes that contain a separating gel are often used to obtain blood serum for laboratory tests. The gel then serves as a barrier to diffusion, preventing contamination of the serum with cellular components.
How do you use a gel clot activator tube?
Usage condition: – Invert the tube for 5-10 times gently. – Wait to complete coagulation after 15-30 minutes. – Centrifuge at 3000-3500 rpm for 10 minutes.
What do you need to know about the SST tube?
The SST™ Tube. There are two kinds of SST™ tubes. One tube has a Gold stopper and the other has a Red-Gray Marble stopper. These tubes have a clot activator on the glass and a polymer gel as the separator. These tubes are used to separate the blood cells from the serum. The tube must be inverted five times following blood collection.
Is there gel in the SST II tube?
The gel in SST II tubes (which appears slightly less opaque) is supposed to have less effect on drug levels in serum. ^ “Blood sampling in sheep” (PDF).
What is SST in lab?
Serum-separating tubes, also known as serum separator tubes or SSTs, are used in medical clinical chemistry tests requiring blood serum. SSTs are sometimes called “marble-top tubes,” “tiger-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 does a gel separator on a blood collection tube do?
It has a mint green stopper. This tube is only used on patients who are in the hospital. This tube contains lithium heparin to keep the blood from clotting and has a gel plasma separator. This tube is used to obtain whole blood, plasma.
