What are the additives in a blood collection tube?
Black Most blood collection tubes contain an additive that either accelerates clotting of the blood (clot activator) or prevents the blood from clotting (anticoagulant). The list below lists the most commonly used blood collection tubes, their additives and uses in laboratory:

What is tested with lavender tube?
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. EDTA Sodium fluoride (serum tube) For glucose determinations. Oxalate and EDTA anticoagulants will give plasma samples.
Are pink and lavender tubes the same?
What are the differences between the lavender stopper and the pink stopper BD Vacutainer K2EDTA Tubes? A. The differences are the types of closures and the labelling. The lavender stopper can either be rubber or a Hemogard™ closure on a plastic tube.
Do you spin lavender tubes?
It is recommended that these tubes are centrifuged after the clot forms and the serum transferred to a separate container. This new container should be labeled with owner name, animal ID, and as serum.
How long is blood in a lavender tube good for?
Tubes of blood are to be kept closed at all times. 2. 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.
What is in a purple top blood tube?
What is a purple top K2 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.
What is clot activator?
Clot activators - glass, silica, kaolin, bentonite, and diatomaceous earth - work by surface dependent mechanism whereas extrinsic biomolecules - thrombin, snake venoms, ellagic acid, and thromboplastin - start in vitro coagulation when added to blood.
How does EDTA prevent clotting?
EDTA can chelate not only calcium but a variety of divalent metal ions to form a stable ring like structure. When calcium is removed from blood sample by adding EDTA in it, specific steps leading to blood clotting will not be completed: hence blood will not clot.
What tube is used for electrolytes?
Gel-barrier tube (send entire tube) preferred.

What happens when you insert a vacutainer tube into a tube?
When a Vacutainer tube is inserted into the holder, its rubber cap is punctured by the inner needle and the vacuum in the tube pulls blood through the needle into the tube.
Who invented vacutainer tubes?
Vacutainer tubes were invented by Joe Kleiner and BD (Becton, Dickinson & Co.) in 1949. These tubes are the registered trademark of Becton, Dickinson & Co. and today vacutainer tubes are manufactured and sold by them.
How does a vacutainer tube work?
Vacutainer tubes work on the pressure difference that is created between the blood vessel and the vacuum in the tubes which forces the blood through the needle into the tube. Vacutainer needle is double-ended, with one side being encased in a thin rubber coating for safety and the other side for the insertion into the vein.
What is a vacutainer tube?
A Vacutainer blood collection tube is a sterile glass or plastic tube with a closure that is evacuated to create a vacuum inside the tube facilitating the draw of a predetermined volume of liquid. Most commonly used to draw the blood samples directly from the vein. These tubes can also be used sometimes for the collection of urine samples.
Why is the exact volume that should be drawn in a specific vacutainer tube mentioned on the label of every?
Moreover, the exact volume that should be drawn in a specific vacutainer tube is mentioned on the label of every tube which is to minimizes the errors that may occur if more or less amount of blood is taken in the tube because every tube contains an anticoagulant or an additive or Clot activator in some and the ratio of the blood to the Additive must be maintained in order to get the accurate values of the tests.
