Pink-top tube (EDTA) This tube contains EDTA as an anticoagulant. These tubes are preferred for blood bank tests. NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.
What does EDTA tube test for?
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 are additives used for in phlebotomy?
Most blood collection tubes contain an additive that either accelerates clotting of the blood (clot activator) or prevents the blood from clotting (anticoagulant).
What are the most common additives in tubes?
- Sodium Citrate tubes: Blue stopper:
- SST tubes: Yellow stopper:
- Heparin tubes: Green stopper:
- EDTA tubes: Purple stopper:
What tubes contain no additives?
6. Red – Tube contains no additive, used for serum chemistry testing, serology, and blood bank testing.
What is heparin tube?
VACUETTE® heparin tubes are used in determinations for clinical chemistry and immunology, hormones, TDM and microbiological serology. Heparin tubes from Greiner Bio-One are available in three different versions: LH Lithium Heparin, LH Lithium Heparin Sep and NH Sodium Heparin.
What is the additive in a red top tube?
Tube cap colorAdditiveRed or gold (mottled or “tiger” top used with some tubes)Serum tube with or without clot activator or gelGreenSodium or lithium heparin with or without gelLavender or pinkPotassium EDTAGraySodium fluoride, and sodium or potassium oxalate
Is EDTA plasma or serum?
“Plasma”is the fluid component of blood. It is obtained when a clotting-prevention agent is added to whole blood and then placed in a centrifuge to separate the cellular material from the lighter liquid layer. Common anti-coagulant agents are EDTA (ethylenediaminetetraacetic acid), heparin, and citrate.
What additive is in the sterile tube yellow?
YELLOW TOP – To be used for leukocyte typings only. Contains Acid Citrate Dextrose Solution A or B (Interchangeable) as a preservative and an anticoagulant. Sterile glass tube. Invert 8-10 times to facilitate mixing and prevent coagulation.
What additive is present in PST tubes?
BD Vacutainer® PST™ Tubes contain spray-coated lithium heparin and a gel for plasma separation. They are used for plasma determinations in chemistry.

What are the additives in blood collection tubes?
The additives may include anticoagulants (EDTA, sodium citrate, heparin) or a gel with density between those of blood cells and blood plasma. Additionally, some tubes contain additives that preserve certain components of or substances within the blood, such as glucose.
Which tube has silica as its additive?
Serum (clot activator) tubes (color dependent on brand: BD is commonly gold but also red, Greiner is red). These tubes have silica particles, which activate clotting. Some also have a gel to separate the serum. Those without the separating gel are potentially more useful in sensitive diagnostic testing.
How do you remember additives in phlebotomy tubes?
Some phlebotomist use a mnemonic to help them remember. Blog Market Lab shared some very humorous mnemonics, such as “Studious Boy’s Rarely Get Low Grades” referring to Sterile, Blue, Green, Lavender and Grey.
How does EDTA work as an anticoagulant?
Ethylenediaminetetraacetic acid (EDTA) strongly and irreversibly chelates (binds) calcium ions, preventing blood from clotting. Citrate is in liquid form in the tube and is used for coagulation tests, as well as in blood transfusion bags. It binds the calcium, but not as strongly as EDTA.
Why is sodium citrate used in blood tubes?
The “citrate tube” is for collecting blood for performing coagulation studies. It contains 3.2% sodium citrate as its anticoagulant. [3] Mixing the blood inside the tube a few times is also recommended to form the plasma. There is no anticoagulant or additive inside the tube.
Which additive promotes clot formation?
Anticoagulants are substances that prevent blood from clotting. Clot activators are substances (eg, glass, silica, thrombin) that promote clot formation. There are many different kinds of anticoagulants used in evacuated tubes.
What is heparin sodium?
About Heparin Sodium HEPARIN is an anticoagulant. It is used to treat or prevent clots in the veins, arteries, lungs, or heart. It stops clots from forming or getting bigger. This medicine prevents clotting during open-heart surgery, dialysis, or in patients who are confined to bed.
What is the difference between EDTA and heparin?
EDTA and citrate remove calcium, which most coagulation factors need. Heparin activates antithrombin thereby inhibiting coagulation by inhibiting thrombin. … Heparin is used for clinical chemistry tests such as cholesterol, CRP, hormones etc. It interferes with PCR, so if you want to do that use EDTA.
What is the additive in the gray top tube?
Gray-top tube: Contains sodium fluoride (a preservative) and potassium oxalate (an anticoagulant). Use: Sodium fluoride whole blood or plasma.
Which tube has thixotropic gel?
ABLight Greenanticoagulant (heparin) & thixotropic gelGreen/Grayanticoagulant (heparin) & thixotropic gelOrangeclot activator (thrombin)Yellow/Grayclot activator (thrombin)
What color tube is used for ESR?
Whole Blood (EDTA) 5 mL whole blood in a lavender-top (EDTA) tube (1.5 mL min). Gently invert tube 8-10 times immediately after drawing to prevent clotting. Store and transport refrigerated. Specimen must be received in the laboratory within 24 hours of collection.
What is EDTA plasma?
EDTA plasma This is the supernatant that is removed after centrifugation of blood collected in a lavender (purple) top tube. This sample should be labeled with the owner name, animal ID, and the words “EDTA plasma”. This is the sample needed for ACTH endogenous and ACTH & insulin.
How do you get plasma from EDTA tubes?
Plasma is produced when whole blood is collected in tubes that are treated with an anticoagulant. The blood does not clot in the plasma tube. The cells are removed by centrifugation. The supernatant, designated plasma is carefully removed from the cell pellet using a Pasteur pipette.
What tube is used for CBC?
The following tests may be drawn in the same LAVENDER (PURPLE) top tube: CBC, SED RATE (ESR), RETICULOCYTE Draw an extra LAVENDER for each (GLYCOHEMOGLOBIN and BNP). 9. GLUCOSE is always drawn in a GRAY top tube. No additional test may be drawn with this tube.
What is SST in phlebotomy?
Serum separator tube (SST) contains a. gel at the bottom to separate blood cells. from serum on centrifugation.
Which additive prevents coagulation by chelating calcium quizlet?
*Citrate– prevents clotting by chelating(binding) calcium, phosphate stabilized pH.
What does EDTA mean in phlebotomy?
EDTA stands for Ethylenediaminetetraacetic acid. EDTA functions by binding calcium in the blood and keeping the blood from clotting.
Which tubes to draw for labs?
- Blood Culture Tubes or Vials.
- Coagulation Tubes (Blue-Top Tubes)
- Serum Tubes without Clot Activator or Gel (Red-Top tubes)
- Serum Tubes with Clot Activator or Gel (Gold or Tiger Top Tubes)
- Heparin Tubes (Green-Top Tubes)
- EDTA Tubes (Lavender-Top Tubes)
What is a tiger top tube used for?
Serum Separator Tube (SST) (Tiger Top): Does not contain an anticoagulant but contains a clot activator and serum separator gel. This tube is used for collecting serum.
