What is the gel in the blood tube?
After centrifugation, the inert acrylic gel at the bottom of the tube normally occupies the middle position between the cells (clot) and the serum, as its density is intermediate between theirs. The gel then serves as a barrier to diffusion, preventing contamination of the serum with cellular components.
What is the yellow stuff in a vial of blood?
Blood plasma is a light amber liquid component of blood that is freed from blood cells, but holds proteins and other constituents of whole blood in suspension. It makes up about 55\% of the body’s total blood volume. It is the intravascular part of extracellular fluid (all body fluid outside cells).
What is the stuff in the bottom of blood vials?
Usually you will see a powder substance at the bottom of each vial. It is an anti-coagulant to prevent the blood clotting. Clotting will affect the results of blood tests, so this substance is added to prevent that from happening.
What is the white stuff at the bottom of a blood vial?
White blood cells and platelets may clump together to form a cellular aggregate. They may appear white or opaque and do not disperse when the container is rotated or shaken. Visible white particles composed of lipid or fat material may also appear in blood samples in patients with hypercholesterolemia.
What color is a gel tube?
Blood Collection Tubes
| Tube cap color | Additive |
|---|---|
| Red or gold (mottled or “tiger” top used with some tubes) | Serum tube with or without clot activator or gel |
| Green | Sodium or lithium heparin with or without gel |

What do the colored blood vials mean?
Each color relates to unique additives that are in the tube. Red: Contain NO anticoagulants, used for serum testing. Gold: Contains a clot activator and special gel to separate serum from the cells. Purple: Contains a clot blocker and are used for complete blood count(CBC). Green & Light Blue: Used for plasma testing.

What do the different colored blood tubes mean?
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.

Laboratory Test Tube Color Guide Common lab tests sorted alphabetically Laboratory Test Tube Color ABG Heparin Syringe – ON ICE ; send immediately to Lab Ammonia Lavender – ON ICE; invert 4-5 times to ensure proper mixing of additives Amylase Green – invert 4-5 times to ensure proper mixing of additives
How many different blood collection tubes are there?
In total, there are 8-12 different blood collection tubes for different tests. The tubes have different top color, additives and purposes. Before we discuss the proper order of draw, let’s discuss first what tubes are used for what blood tests:
What is the correct order for drawing tubes in the lab?
Correct order for drawing tubes: Blue, Gold or Red, Green, Lavender or Pink Note: One inversion is upending the tube 180 degrees, then returning it upright. For questions or for tests not listed, please call the Laboratory at 815-3334
What is the color of the aPTT test tube?
not present Laboratory Test Tube Color APTT Blue – invert 4-5 times to ensure proper BMP (Basic Metabolic Panel) Includes: N Green – invert 4-5 times to ensure prope Bilirubin Green – invert 4-5 times to ensure prope Blood Cultures Kit from Lab (call x3334)
