What color tube is serum collected in?
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 the container of choice for collection of serum?
Red-top tube, plastic It is used for collection of serum for selected laboratory tests as indicated. If the specimen requirement for a test is red-top tube(s), do not use gold-top/SST® tube(s), as the gel separator may interfere with analysis.
How is a serum sample collected?
Collection Procedure 1) Collect blood in appropriate serum separator tube. 2) Gently invert the tube 8-10 times, and let tube sit in an upright position for at least 15-30 minutes at room temperature to allow the blood to clot. 3) Label sample with appropriate study code.
What color tubes are used for which tests?
Blood Collection Tubes
| Tube cap color | Additive | Common laboratory tests |
|---|---|---|
| Lavender or pink | Potassium EDTA | Hematology and blood bank |
| Gray | Sodium fluoride, and sodium or potassium oxalate | Glucose (especially when testing will be delayed), blood alcohol, lactic acid |
Why are serum separator tubes used?
Serum separator tubes were introduced 35 years ago and were widely used in the clinical laboratory in China for routine collection of blood because of providing a closed system that allowed for collection, transport, processing, sampling, and storage of specimens.

What are specimen containers?
Specimen collection containers consist of any number, shape and size of container for collecting urine, stool, mucus or other type of bodily fluids. Fluids are typically collected for testing at in-house or outside facilities such as a third-party hospital test site or a sterile testing room.
What is a EDTA tube?
It’s a tube coated with spray-dried K2EDTA on its inner wall. EDTA acts as an anticoagulant, binding the calcium ions and interrupting the clotting of the blood sample. EDTA is used for most hematology procedures, assessing complete blood count, preparing EDTA plasma, whole blood collection and bone marrow specimens.
What is EDTA bottle used for?
Additive. Purple blood bottles contain EDTA (ethylenediaminetetraacetic acid), which acts as a potent anticoagulant by binding to calcium in the blood. EDTA also binds metal ions in the blood and is used in chelation therapy to treat iron, lead or mercury poisoning.
What are the different Colour bottles for blood tests?
There are two types of the green top bottles:
- Light green: contains lithium heparin additive (anticoagulant) and a gel separator.
- Dark green: contains sodium heparin additive (anticoagulant)
What is the gel in a serum separator tube?
Serum separator gel tubes contain an inert, thixotropic poly- mer gel which has a density between that of serum and clot. Hence, a barrier consists of between the liquid and the cellu- lar components after centrifugation that prevents the mixing of substances originated from cells to the serum [2].
