What is the SST tube used for?
Serum Separator Tube (SST®) This tube contains a clot activator and serum gel separator. It has no anticoagulant and is used for many chemistry tests. It cannot be used for certain drug levels or any blood bank procedures.
What is the gel at the bottom of the SST 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.
What color is serum tube?
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 is a gold SST blood test for?
Specimen required: 5ml serum SST (Gold top) Tests are performed by the immunology department at St Richards Hospital. This combined test will detect auto antibodies to gastric parietal cells; mitochondria; smooth muscle and liver-kidney microsomes.
What blood test goes in what color tube?
The tests each bottle is used for are the same: the purple one is for cell count, the yellow one is for electrolytes, albumin and LDH, the grey one is for glucose, and blood culture bottles can be used for fluid cultures.
What color tube is used for a PT INR?
light-blue
A light-blue top tube (containing 3.2% sodium citrate) that will be used for coagulation testing must be filled to completion.
How does an SST tube work?
Trademarked versions of the SST include Covidien “Corvac” tubes. They contain a special gel that separates blood cells from serum, as well as particles to cause blood to clot quickly. The blood sample can then be centrifuged, allowing the clear serum to be removed for testing.
How many times do you invert a SST tube?
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 is a yellow top tube used for?
Yellow-top tube (ACD) This tube contains ACD, which is used for the collection of whole blood for special 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.
