What is 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 color tube is CRP?

RedCollection Instructions: Red-top tube should be centrifuged and the serum aliquoted within 2 hours of collection.

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.

How much serum is in a SST tube?

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

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.

How long can blood sit in tubes?

Whole blood can be stored at 4–8°C for up to 24 hours before the serum is separated, but it must not be frozen. Whole blood should be allowed to clot and then centrifuged at 1000 × gravitational units (g) for 10 minutes to separate the serum.

Do you spin lavender tubes?

What is the purpose of an Antiglycolytic agent?

There are a series of other agents used in conjunction with or without the anticoagulant. They are antiglycolytic agents, clot activators, and thixotropic gel separators. The antiglycolytic agent is a substance that inhibits glycolysis or metabolism of glucose by the cells of the blood.
