What does SST tube test for?
SST Gold – Tube contains Clot Activator / SST™ Gel separator, used for serum chemistry testing. Mix by inverting 5 – 10 times immediately after collection. 6. Red – Tube contains no additive, used for serum chemistry testing, serology, and blood bank testing.
When should a SST blood tube be mixed?
Mix. Immediately after collection, before clotting can occur, gently mix the blood collection tube by inverting 8-10 times.

What is yellow top blood test for?
The yellow blood bottle can be used to test for a wide variety of bacterial, viral, fungal and parasitic infections including HIV and viral hepatitis.
Is SST a gel barrier tube?
Clot activator and gel for serum separator Serum separator tube (SST) contains a gel at the bottom to separate blood cells from serum on centrifugation.
How do you process a SST tube?
To obtain serum, whole blood should be collected into either an SST or plain red top tube. After collection, allow the tube to sit in an upright position at room temperature for 30-45 minutes. After the clot has formed, centrifuge the tube for 10 minutes at 3400 rpm.
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].
What is the difference between a PST tube and a SST tube?
The Plasma Separator Tube, also referred to as PST™, contains lithium heparin and plasma separator gel; whereas, the Serum Separator Tube, also referred to as SST™, contains a clot activator and a serum separator gel.
What is the difference between a red serum tube and an SST tube?
Red Top: Does not contain an anticoagulant. This tube is used for collecting serum or clotted whole blood specimens. This tube should be used for all drug levels. Serum Separator Tube (SST) (Tiger Top): Does not contain an anticoagulant but contains a clot activator and serum separator gel.
