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 tube has a clot activator?

Red-top tube: Tube does not contain an anticoagulant. 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 is a 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 is in an SST tube?

SST refers to the Serum Separator Tube containing clot activator and serum separator gel. PST refers to the Plasma Separator Tube containing lithium heparin and plasma separator gel.

What blood tube colors are for which test?

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 percentage of blood is serum?

It serves as the liquid base for whole blood. Whole blood minus erythrocytes(RBCs), leukocytes(WBCs) and thrombocytes(platelets) make up the plasma. Serum, sometimes mistakenly considered synonymous with plasma, consists of plasma without fibrinogen. Plasma contains 91% to 92% of water and 8% to 9% of solids.

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.

At what speed do you centrifuge blood?

Allow the blood to clot in an upright position for at least 30 minutes but not longer than 1 hour before centrifugation. Centrifuge for at least 15 minutes at 2200-2500 RPM within one hour of collection.

What does the 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.

How much serum is in a SST tube?

1.0 mL of serum is the minimum acceptable volume needed for testing.

How do you use SST tube?

When using a serum separator tube, collect the specimen using standard venipuncture technique. Gently invert the tube five (5) times to mix the clot activator with the blood. Avoid vigorous agitation of collected specimens. Allow the tube to clot for 20-30 minutes in a vertical position.

How long can an SST sit unspun?

Specimen stability: Unspun whole blood (room temperature): 2 hrs. Spun SST: Refrigerated: 3 days. Spun PST: Refrigerated: 12 hours.
