Serum-separating tube (SST): Tube inversions promote clotting. Most chemistry, endocrine and serology tests, including hepatitis and HIV. Orange Clot activator and serum separating gel [5] Rapid serum-separating tube (RST). Dark green Sodium heparin (anticoagulant) Chromosome testing, HLA typing, ammonia, lactate: Light green Lithium heparin ...
A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper creating a vacuum seal inside of the tube, facilitating the drawing of a predetermined volume of liquid. Vacutainer tubes may contain additives designed to stabilize and preserve the specimen prior to analytical testing.
These tubes should be used with care when measuring drug or hormone levels because the drug or hormone may diffuse from the serum into the gel, causing a reduction in measured level. The gel in SST II tubes (which appears slightly less opaque) is supposed [weasel words] to have less effect on drug levels in serum. [citation needed]
These tubes are manufactured with a specific volume of gas removed from the sealed tube. When a needle from a hub or transfer device is inserted into the stopper, the tube's vacuum automatically pulls in the required volume of blood. [citation needed] The basic Evacuated Tube System (ETS) consists of a needle, a tube holder, and the evacuated ...
A venipuncture performed using a vacutainer. A venipuncture is useful as it is a minimally invasive way to obtain cells and extracellular fluid from the body for analysis. Blood flows throughout the body, acting as a medium that provides oxygen and nutrients to tissues and carries waste products back to the excretory systems for disposal ...

Whole blood is taken with either citrate or oxalate additive (if using the vacutainer system, this is a light blue top tube). As with other coagulation assays, the tube must not be over- or under-filled in order to ensure the correct anticoagulant-to-blood ratio: one part anticoagulant per nine parts blood.
Unprecedented evidence humans occupied ‘lava tubes’ could fill in gaps in the archaeological record, scientists say. Mindy Weisberger, CNN. May 8, 2024 at 6:17 AM.
